Since when diabetes mellitus It is important to monitor blood glucose levels every day, patients most often do biochemical analysis blood at home. For this purpose, special devices are purchased that allow you to carry out measurements independently, without visiting a clinic.

Among diabetics, the EasyTouch universal device for measuring sugar, cholesterol and uric acid from Bioptik is in great demand. There are several types of devices in this series, which are distinguished by the accuracy of their indicators and the ability to measure several parameters at once.

This is a high-quality, convenient and compact meter with minimal error. Patients can carry it with them in their purse and conduct testing at any convenient time. The device uses an electrochemical diagnostic method, which is a big plus.

Using the EasyTouch GCHb

This is an excellent option for people diagnosed with diabetes who carefully monitor their health and monitor any changes in blood composition. The EasyTouch analyzer tests for glucose, cholesterol and hemoglobin levels. This model has a liquid crystal display with large symbols, so the device is convenient for the elderly and patients with poor vision.

The glucometer can independently adapt to the right type measurements after a special test strip is installed in the socket. At first it may seem that the device is difficult to operate, but after studying the instructions it will become clear that it has simple functions and is easy to configure.

To test blood for sugar, use capillary blood from a finger in an amount of no more than 0.8 μl. To measure the concentration of cholesterol, take a double dosage, and to test for hemoglobin - a triple dosage.

The advantages of this device include the following features:

• You can get results for diagnosing hemoglobin and sugar in 6 seconds, and determining cholesterol levels takes 2.5 minutes, which is quite fast.
• The analyzer's memory stores the last 200 measurements, indicating the date and time of the study.
• The measurement range for sugar is 1.1-33.3 mmol/l, cholesterol – 2.6-10.4 mmol/l, hemoglobin – 4.3-16.1 mmol/l.
• The dimensions of the device are 88x64x22 mm and the weight is only 59 g.

The kit includes an instruction manual, a test strip to check the accuracy of the device, two AAA batteries, a set of 25 lancets, a pen, a case for storing and carrying the device, an observation diary, 10 test strips for sugar analysis, 5 for hemoglobin and 2 for cholesterol. The cost of such an analyzer is 5,000 rubles.

Thanks to a unique meter, diabetics can conduct a test without leaving home in a matter of minutes. It is especially important to monitor cholesterol levels in order to promptly notice lipid metabolism disorders and take action. In case of undesirable changes, the doctor will prescribe a therapeutic diet, and it will also be necessary to healthy image life.

Before testing, the patient must be calm for at least 15 minutes.

Diagnostic results can be affected by stress, physical strain and overeating, so these factors must be excluded.

Using the EasyTouch GCU and GC

Sugar level

The EasyTouch GCU analyzer analyzes the levels of glucose, cholesterol and uric acid using an electrochemical diagnostic method. For testing, capillary blood taken from a finger is used.

To obtain reliable results, it is necessary to extract 0.8 μl of biological material when studying glucose and 15 μl to study cholesterol indicators.

The results of the study of sugar and uric acid can be found out in 6 seconds, the level of lipids is displayed on the device display after 150 seconds.

This device is also capable of storing latest results diagnostics, which is very convenient for patients who prefer to track statistics of changes. The cost of such a device is 4,500 rubles, which is not expensive.

Easy Touch GCU blood analyzer for glucose, cholesterol, uric acid includes:

1. Operating instructions for the analyzer in Russian;
2. Two AAA batteries;
3. A set of lancets in the amount of 25 pieces;
4. Piercing pen;
5. Observation diary;
6. Test strips for measuring sugar and uric acid, 10 pieces each;
7. Two test strips for cholesterol analysis.

Unlike the two above models, EasyTouch GC is considered a budget and lightweight option; it can only measure cholesterol and sugar levels.

Otherwise, the parameters and functions are no different from previous devices; its research range is similar.

You can buy such a device at a pharmacy or specialty store for 3000-4000 rubles.

Instructions for use of the device

Before performing diagnostics at home, you should read the included operating instructions for the meter. Only if you follow all the specified recommendations and rules will you be able to determine the most accurate blood glucose level without errors.

When you turn on the device for the first time, you need to enter the date and time and set the necessary units of measurement. To test your blood, you will need to purchase an additional set of test strips.

When purchasing consumables, you need to pay attention to the name of the model, since the blood analyzer for glucose, cholesterol, uric acid requires the use of individual test strips; they will not work with any other meter.

To obtain the most accurate data and avoid errors, you must adhere to following rules specified in the instructions:

• Hands are washed with soap and thoroughly dried with a towel.
• The measuring apparatus is placed on the table. The lancet is installed in the lancing pen, after which the test strip is placed in a special socket.
• The finger is treated with alcohol solution, after which it is lightly massaged and pierced.
• It is recommended to remove the first drop of blood with a cotton swab or sterile bandage; the second drop of biological material is used for testing.
• After receiving the required volume of blood, the finger is brought to the surface so that the liquid can be independently absorbed into the surface intended for this.

When the alert sounds, you can see the diagnostic results on the meter display. The cholesterol reading will appear later because this testing takes longer. The obtained data is automatically saved in the device indicating the date and time of measurement.

Batteries are used as a power source, so you should take care of buying a spare pair and carrying them with you in your purse. In order for the research results to be accurate, you need to use only high-quality and suitable consumables.

Under no circumstances should you use expired test strips; such materials can be stored for no more than three months, after which they are disposed of. The exact date of manufacture and expiration date can be seen on the case.

According to reviews from doctors and patients, the clear advantages of EasyTouch include the following features:

1. This is a fairly accurate device with a maximum error of 20 percent, which is the standard for such home portable devices.
2. The device is compact in size and weighs very little, making it ideal for carrying and traveling.
3. The special GCU model is the first and only portable device on Russian market, which can test your blood for uric acid levels.
4. During the analysis, a modern electrochemical diagnostic method is used, so the glucometer does not contain fragile or high-maintenance optical elements, and the accuracy indicator does not depend on lighting.

The kit includes everything necessary for a diabetic, so a blood test can be performed immediately after purchasing the meter. The first test can be carried out right in the store to check the operation of the device and learn how to use it.

To prevent the development of atherosclerosis, a diabetic must monitor his blood condition every day. In the event of a sharp increase in indicators, you must immediately contact medical care. A special product will help you get rid of harmful lipids therapeutic diet no fatty or high carbohydrate foods.

The rules for choosing a glucometer are described in the video in this article.

question:
You don’t have to rush to the hospital for blood tests. And with gout and diabetes, and even with diet you have to. Now, if only there was some indicator of urea and blood sugar at home, huh?

Home device for determining the amount of uric acid in the blood

Medical equipment: home laboratory

It would be more correct to say:
home device for determining the CONCENTRATION of uric acid in the blood.

Why determine the concentration of uric acid?

The effectiveness of diet and drug treatment against gout is ultimately determined by the conversion of purine proteins into uric acid salts - determined on a specific organism, on a specific patient in real time.
Contrary to strict diet ate a kebab - you get tophi, an attack of gout (remember in some material - “a leg in a trap”?) and... data on the content of uric acid. Agree, the latter is the most painless or non-unpleasant.

Express data allows you to monitor your diet and adjust it, and make an individual selection of products (of almost unknown composition - see).
Thus, a portable express uric acid analyzer helps treat gout with diet (not completely, but dietary nutrition is an essential part of the treatment of gout).

Two interesting questions regarding non-laboratory measurement of uric acid concentration in a person (living!)

• What kind of blood: from a vein - venous - or from a capillary ("finger") - capillary? Outside the laboratory, numerous organizations that protect humans do not allow taking blood from a vein from a living person, or even picking at the veins. Setting up “systems” (infusion system, drip) is a separate issue. Therefore, the rapid test device uses capillary blood, although its composition is somewhat different from laboratory venous blood.
• Determining the concentration of uric acid in urine (urine) or blood? There are no words in urine; determining uric acid is simpler and more technologically advanced. But waste is discharged into the urine - that which is not deposited in the gouty joints (including :-), and in the arterial (capillary) blood - that which can be absorbed by the body.

Home device for determining uric acid, glucose, cholesterol in the blood

Taking into account these functions of uric acid in a living person, in the complex “salt + protein metabolism"(substances - NNN's note), and if for diseases, then "gout + diabetes" a "medical tester" was created - EasyTouch ® GCU system. By the way, the only multi-tester - combines measurements for glucose and uric acid and cholesterol .

Self-testing EasyTouch ® GCU blood sugar (more correctly - glucose) - cholesterol - uric acid, that is, it is a multifunctional monitoring system (in vitro). EasyTouch ® GCU can be used by both the patient and medical staff. Known difficulties (purely “technological”) are presented by the correct collection of blood “from a finger,” but a spring “gun” greatly simplifies this task. The main thing is that EasyTouch ® GCU users have the opportunity to quickly and cheaply control blood sugar, cholesterol and uric acid.

Company prices for devices measuring the concentration of uric acid, cholesterol, blood sugar

The price of a uric acid level detector (I saw it on the national official website of the company - its representative office) July 7, 2015 (no discounts were offered) - easytouch.bg/?page_id=126:

EasyTouch GU kit
measurement of uric acid, blood sugar - price 46.15 euros (currency calculator, who opened the current page)

EasyTouch GCU Kit
measurement of uric acid, blood sugar AND CHOLESTEROL - price 76.92 euros (currency calculator, who opened the current page).

Prices for consumables for GU-GCU indicators - cost of branded test tapes

The device is powered by a standard AAA (small finger) battery.

In fact, the price for one measurement of blood parameters:

Price of "branded" test tapes (additional):
Price for uric acid test tape: 25 tests - 15.38 euros.
Blood sugar test tape price: 25 tests - 12.82 euros.
Cholesterol test tape price: 10 tests - 20.51 euros.

Cost of blood tests and efficiency - price

At the same time, in a medical laboratory at a clinic or hospital, a blood test from a vein for one parameter costs (low cost) 2-3 leva. Through the compulsory medical system. insurance (permanent insurance policy), the blood test is done virtually free of charge. But at the same time there is a lot of bureaucracy, time and transportation costs that cannot be estimated.

Thus, the only consumables used in the device (gadget) are a special test strip, and medical alcohol can be replaced with vodka or diluted acetic acid to disinfect capillary sampling of blood drops from a finger.

Uric acid is one of the most important nitrogen-containing components of urine. When eating meat, the amount of uric acid in the urine increases and decreases when eating plant foods. The daily normal amount of uric acid excreted in urine is 0.3-1.4 g (on average 0.8 g). An increased amount of uric acid secreted in the urine is observed in pneumonia, leukemia, gout attacks, and after the use of salicylic sodium.
At diabetes, and also after taking certain medications (quinine, antipyrine, methenamine, etc.), uric acid is excreted in the urine in smaller quantities.

Qualitative method. Murexide test. 2-3 drops of test urine are dipped into a porcelain cup, mixed with 2-3 drops of nitric acid and dried in a water bath, after which a small reddish coating remains. 1-2 drops of ammonia are applied to this plaque, which causes a purple-red color (murexide - ammonium purpurate), which turns purple with the addition of one drop of caustic alkali.

Quantitative method. This method is based on the precipitation of uric acid in the form of ammonium urate, the amount of which is then calculated by titrating it with a solution of potassium permanganate.

Necessary reagents : 1) 1/500 g of ammonium sulfate poured into a liter flask, dissolved in 600 ml of distilled water, add a mixture of 5 g of uranium acetate dissolved in 100 ml of distilled water and 6 ml of strong acetic acid, after which it is poured into the flask to the mark one liter of distilled water.
2) strong sulfuric acid(H2S04).
3) 25% ammonia and
4) 1/50 normal solution of potassium permanganate. Method of determination: add 2 ml of reagent No. 1 (a solution of ammonium sulfate with uranium) to a test tube with 8 ml of urine, leave until a precipitate forms (72 hours), then filter and 7.5 ml of the filtrate, which is equal to 6 ml of urine, is poured into centrifuge tube, add 10-15 drops of ammonia (reagent No. 3), cover with a stopper and leave for 10-15 hours. The result is a precipitate of uric acid in the form of ammonium urate.

Uric acid ammonium centrifuge, drain the liquid, add again 6-8 ml of reagent No. 1, mix and centrifuge again, then drain the liquid. 3-5 ml of distilled water, 1 ml of sulfuric acid (reagent No. 2) are added to the resulting precipitate, stirred with a glass rod and the resulting hot liquid is titrated with a 1/50 solution of potassium permanganate (reagent No. 4) until a pink color appears that does not disappear within 10 seconds. . Calculation: the number of milliliters of potassium permanganate solution used during titration is multiplied by 1.5, since 1 ml is 1/50 N. potassium permanganate solution corresponds to 0.00150 g or 1.5 mg of uric acid.

Receive quantity milligram uric acid in 8 ml of test urine. To calculate the amount of uric acid in the daily amount of test urine (1500 ml), you need to multiply the number of milliliters of potassium permanganate solution by 1.5, divide by the amount of tested urine (8 ml) and multiply by the daily amount of test urine (1500 ml).

Uric acid is a substance that is formed in the human body at the end of the breakdown of purine nucleotides. The metabolite contains nitrogen, and with the help of uric acid the body can get rid of excess nitrogen.

The breakdown of purine nucleotides in men and women occurs in the intestines, liver and kidneys. Uric acid then enters the blood and is excreted by the excretory system. The normal value of the parameter is determined by the age and gender of the patient.

Disorders of purine metabolism lead to the accumulation of metabolic products in the human body and tissue damage, which provokes symptoms of pathologies. Treatment should be as correct as possible.

Normal uric acid concentration values

For children, women and men, the norm of metabolite concentration in blood serum during analysis is different. The table will help you figure this out:

Factors influencing the result of uric acid determination

The following factors may influence the value of this indicator when analyzing it:

Foods that the diet includes. The content of the purine metabolic product in both blood serum and urine can be increased by some foods of animal origin. The diet for both men and women should be rational and complete.

Age. As age increases, the number of cells that complete life cycle, as a result of which the intensity of the breakdown of purine nucleotides increases and, accordingly, uric acid is formed in larger quantities.

Gender differences. In men, the norm of the parameter in the blood is slightly higher than in the fair sex, which is associated with a large volume of muscles and the effect of testosterone.

Physical activity. Intense loads increase the breakdown of purine nucleotides, and uric acid is formed in a larger volume. The concentration norm is not violated.

Smoking due to hypoxia can provoke an increase in the concentration of the metabolite in the blood.

Sunlight, drinking alcohol.

Pregnancy. When carrying a child in the first and second trimester, the concentration of the purine metabolic product decreases, and in the third it increases.

Treatment with agents that can cause uric acid to either increase or decrease.

Effect of drugs on uric acid concentration

Some medications used to treat diseases can change the content of the purine metabolic product in the blood serum in men and women, which can be detected by analysis. Treatment with their help can provoke symptoms of pathologies. Drugs that increase the concentration of a substance include:

• aspirin;
• beta blockers;
• diuretics;
• epinephrine;
• antiviral agents;
• antibiotic drugs;
• immunosuppressants;
• hematopoietic stimulants;
• antitumor drugs;
• glucocorticosteroid drugs.

Drugs that reduce the concentration of the metabolite during analysis include:

• allopurinol;
• some antibiotics that are used to treat infections;
• probenecid;
• antipsychotics;
• drugs that reduce lipid concentrations;
• oral contraception;
• substances that are used for contrast during x-rays.

Reasons for the increase in uric acid concentration

Hyperuricemia, that is, a condition when the analysis is increased, can be caused by a number of reasons.

Excess intake of purines into the body in foods that the diet includes. If a person consumes animal products in excess, the level of the metabolite increases due to the fact that such products contain more purine nucleotides. The solution in this situation is a rational diet.

Increasing the activity of substance formation in the body. This can be caused by cell death due to pneumonia, anemia, rhabdomyolysis, psoriasis, polycythemia, leukemia, chemotherapy, ammonia or lead poisoning. Also, the formation of the metabolite increases with a decrease in blood pH during lactic acidosis, ketoacidosis, and fasting.

Difficulty in excreting the metabolite by the excretory system. This can occur with kidney failure, gestosis, polycystic disease, and poisoning.

Reasons for decreased uric acid concentration

The list of reasons that can lead to a decrease in the level of purine metabolism product in the body during analysis includes treatment with certain medications, the list of which is presented above. Also, the concentration of this substance in men and women can be reduced as a result of certain pathologies, namely Fanconi syndrome, Wilson-Konovalov disease, celiac disease, Hodgkin's disease and some others, each of which has its own symptoms. Following a vegetarian diet may also reduce uric acid levels, as plant products contains less purines, and such a diet is not complete.

The value of determining uric acid

The determination of this substance in blood serum, which is included in the biochemical analysis, is required to assess purine metabolism in the body. The calculation formula for studying a parameter may differ in different laboratories. Fluctuations in the parameter value during analysis make it possible to confirm or refute a preliminary diagnosis and prescribe treatment that will help get rid of the pathology. Uric acid can provide information about the functioning of the liver, organs of the excretory and hematopoietic systems, and muscles in the body.

To correct the metabolite content, you should follow the correct diet. The diet should include products of both animal and plant origin. Compliance with the regime that the diet creates will allow you to maintain the level of the substance in the range that the norm suggests, and healthy foods have a beneficial effect on the body as a whole. Diet is one of the best measures to prevent fluctuations in uric acid levels in both men and women.

A chemical examination of urine is performed to qualitatively and semi-quantitatively identify components that have the ability to dissolve in water and, under normal conditions, are absent from the biofluid.

The presence of such elements in urine indicates the presence of pathological abnormalities of the paired organ or indicates a violation of the metabolic process. For the study, preference is given to morning urine because it is considered to be the most concentrated. Checking allows you to almost completely eliminate negative indicators.

What is a urine dipstick test?

For urine analysis are represented by one or more chemical reagents used for research in stationary laboratories. They are applied to a plastic or thick paper base, the dimensions are six by thirteen centimeters with a five-millimeter thickness.

The reagent is an indicator for testing, capable of changing its own shade when in contact with sediment components found in biological fluid.

The reagent indicator is selected taking into account the type of pathology to be detected. There are strips with only one applied reagent. They are called single-indicator; you can check the content level of only one element.

There are test strips with a whole range of different reagents designed to perform comprehensive examination. Such tests are called multi-indicator tests.

The test kit includes:

Purpose

The strips are intended for quick analysis of urine not only at home, but also with the use of analyzers that help determine the characteristics of biological material.

Determining a qualitative indicator involves identifying a certain component that confirms the presence of a particular pathology. Changes in the shade of the indicator element clearly indicate the presence of a metabolite and relate to the reaction positive character. A semi-quantitative indicator involves determining the volume of identified inclusions by visualizing the color level of the reactive element.

Test strips are used to monitor the status of a previously identified disease and to detect new pathological abnormalities. These include:

• diabetes;
• glucose deficiency in women during pregnancy;
• infectious diseases in the ureteral canals;
• non-infectious lesions of urine excretion pathways;
• education .

An express method of self-diagnosis using visualization of indicator elements cannot replace a normal urine test conducted in a stationary laboratory.

Types of test strips

Today, many countries are engaged in the production of test strips. Well-known companies include:

• Russian – “Bioscan” and “Biosenor”;
• Korean – Uriscan;
• Canadian - Multicheck;
• Swiss - Mcral-Test;
• American – UrineRS.

Any manufacturer provides an extensive list of diagnostic kits that help check a variety of parameters:

• glucose;
• red blood cells, protein, density indicator;
• , nitrites, bilirubin.

The combination of an indicator from several reagent elements in one test makes it possible to optimize diagnostic performance, taking into account the goals being pursued. For example, to monitor sugar levels in diabetes, an indicator element that reacts to glucose and ketones is applied to the test strip. In cases with symptoms, it is recommended to use strips that combine the following indicators:

• blood;
• squirrel;
• nitrites;
• glucose;
• ketones.

It is believed that any manufacturer produces test strips that are used not only for visual examinations, but also with instrumental ones, when analyzers are used.

Terms of use

1. Do not touch the indicator part of the strip.
2. Carry out the procedure at a temperature of fifteen to twenty-five degrees Celsius. Under colder conditions, the reaction rate is significantly reduced, which leads to false results.
3. If the urine was in the refrigerator, it must be heated to the desired temperature.
4. Storing biological fluid selected for testing for more than two hours is prohibited. Otherwise, the physicochemical parameters of urine change.
5. Do not reuse the same strip.
6. It is not recommended to immerse the indicator in urine for for a long time– there is a possibility of leaching of the reagent element from the surface of the strip.
7. After opening the package, all tests must be used within the period specified by the manufacturer - no later than six months.
8. Do not expose the scale to ultraviolet light for long periods of time to prevent the colors from fading.

Diagnostic test procedure

The entire process of performing express analysis is divided into several stages:

Analysis transcript

Let's try to consider the most well-known components of urine that can be checked using test strips, and study their characteristics.

Leukocytes

The leukocyte indicator is used to detect inflammation in the ureteral canals - cystitis, pyelonephritis, glomerulonephritis. As soon as the reagent applied to the test reacts, the shade of the scale changes. The reaction is considered positive if yellow will turn purple.

Glucose

Its presence in urine is called. The indicator confirms the excess of the amount of glucose in blood cells in relation to the renal threshold. This situation is possible in diabetes or renal glycosuria, when the tubular type reabsorption mechanism is impaired.

Test strips are convenient for checking glucose levels because they contain the enzyme glucose oxidase and peroxidase in the indicator, which react with glucose and produce a color change from green to brown.

Excess sugar in the urine of a pregnant woman does not always confirm the appearance of diabetes. Sometimes this is caused by temporary deviations in the performance of the paired organ.

Ketone bodies

This is the result obtained after the oxidation of fatty acids. An increase in concentration occurs due to a lack of carbohydrates or the inability of tissues to process glucose. This condition, when ketone levels increase, is called ketoacidosis. Its occurrence is confirmed by changes in the shade of the strip from light pink to burgundy.

Squirrels

Test strips for identifying this component are used mainly when there is a suspicion of failure of a paired organ. The reaction process is based on the ability of tetrabromophenol, which is part of the reagent, to interact with proteins, resulting in a colored complex.

A positive reaction is accompanied by a change in the shade of the pale yellow indicator to a bright green color. The minimum sensitivity to protein concentration in urine is 0.06 g/l.

Blood

If detected, a scale with an indicator has one or two sectors that react exclusively to hemoglobin. The lowest level to be determined can vary, ranging from five to ten red blood cells in 1 μl and ten milligrams of hemoglobin in 1 μl.

If the reaction ends positively and the shade of the reagent changes, dots are observed in the first part of the sector, and the second half is painted with a uniform shade of dark green or blue.

Taking into account the fact that with hematuria protein often appears in urine, it is recommended to use strips that combine hematuria and reagents.

The presence of blood in urine quite often causes infection or injury to the ureteral canal, bleeding in the paired organ.

Acidity

Clarification of urine acidity level in home environment considered a simple matter. The acidity index of a biological material determines which type of salts predominates, which is considered very important in research and subsequent treatment. When measuring the acidity level, the shade of the indicator line varies with orange color to green-blue.

The acidity level of urine can vary depending on food, medicines, renal pathologies.

Density

Urine testing for this indicator is carried out when examining drug addicts or athletes who are suspected of taking doping drugs.

Under normal conditions, the specific gravity of urine is considered to be 1.010 – 1.025. An increase in density may be observed during inflammatory processes in the kidneys, diabetes, paired organ failure.

Urobilinogen and bilirubin

An increase in their content confirms abnormalities in the functioning of the liver and bile ducts. The measurement scale has a minimum level of 2 mg/l, and a maximum level of 80. An increase in the content of these elements will cause an increase in the color saturation of the indicator line. A positive test for bilirubin confirms the presence or development of hepatitis.

Creatinine

Tests for this element are used in cases where there are symptoms of abnormalities in kidney function, hormonal imbalances, and diabetes. Creatinine is actively involved in energy metabolism tissue cells, its level depends on muscle mass.

Based on the fact that the muscle indicator remains practically unchanged, the creatine level will also be constant. Its increase in urine is caused by kidney failure, dehydration, a diet with a predominance of meat, and physical stress.

Nitrites
