Glycated hemoglobin is present in the composition of red blood cells. A blood test for HbA1 should be done regularly; any deviations from the norm in women require an immediate visit to the doctor. You need to properly prepare for the delivery of the biomaterial in order to eliminate errors in the results.

What is glycated hemoglobin and what is it responsible for in the body?

insta story viewer

Glycated hemoglobin (the norm in women is determined depending on a number of factors) is divided into several fractions. This substance helps to determine the concentration of sugar in the blood over a long time period (90-120 days). Glycohemoglobin is formed when glucose combines with blood protein. The process initiates the Mayer reaction.

If the concentration of glucose in the blood is increased (usually this happens in diabetes mellitus), then the level of hemoglobin also rises. On average, red blood cells (erythrocytes) "live" for several months, so the analysis for glycated hemoglobin helps to reveal the degree of glycemia in 100-120 days.

Glycohemoglobin can be considered an indicator of blood glucose. Any deviation from the norm, especially an increase in values, may indicate the development of diabetes.

Norms in women

The norms of glycohemoglobin do not vary greatly depending on gender. Indicators are assessed as a percentage. If a woman is not pregnant and does not suffer from diabetes mellitus, then the optimal value varies in the range of 4.2-5.6%. An increased rate may indicate the development of diabetes mellitus. In this case, the patient needs to visit a doctor who will correct the diet and, if necessary, prescribe medications.

According to the age

Glycated hemoglobin (the norm in women is an average indicator) in the blood is present in different concentrations. The values ​​may vary depending on the age of the patients. This is due to the slowing down of natural processes.

Indicators of glycated hemoglobin, depending on the age of the woman:Glycated hemoglobin. The norm in women by age. table

Age The values
25-35 years old 5,8-6%
35-45 years old 6-6,3%
45-55 years old 6,5-7%
55-65 years old 6,8-7%
65-75 years old 7-7,2%
80 years and more Not more than 7.5%

A sudden increase in indicators may indicate the development of diabetes mellitus.

During pregnancy

During pregnancy, the norm is considered to be indicators of 6.5-6.8%. An increase in glycohemoglobin in a woman with diabetes may indicate a high risk of miscarriage in the first or second trimester. It is also extremely dangerous for the fetus - the process of its formation in the womb slows down, so the child can be born with a congenital defect. High scores indicate gestational diabetes. With gestosis and diabetes mellitus in a pregnant woman, according to studies, a child may be born with obesity or prediabetes.

With diabetes

For patients with diabetes, experts recommend regularly donating blood for glycated hemoglobin. The analysis allows you to control the concentration of sugar, monitor the effectiveness of drug therapy and, if necessary, adjust the diet.

Normal rates for diabetics should not exceed 7.8-8%. An increase, however small, may indicate the development of various life-threatening conditions. It is impossible to urgently reduce the concentration of glycated hemoglobin - the body is already accustomed to such a level of glucose in the blood. A sharp decrease in indicators can negatively affect the patient's well-being.

What analysis determines the level of glycated hemoglobin, where to do it and how much it costs

Glycated hemoglobin (the norm in women is determined by a laboratory method) is formed when blood protein and glucose combine. You can take the analysis in any private and public laboratory. The cost of the procedure varies between 350-550 rubles. Some institutions undertake to provide the patient with a result after 14-24 hours. after analysis. The client may have to pay extra for the urgency.

Indications for analysis for the level of HbA1

Glycated hemoglobin rises for a number of reasons. Deviations from the norm in women may indicate the development of life-threatening pathologies. A blood test should be taken not only for diabetics, but also for completely healthy people. Glycated hemoglobin values ​​may rise or fall suddenly. If the indicator increased from 5.6% to 6%, then the patient is more likely to develop prediabetes.

According to statistics, people with high glycohemoglobin die from myocardial infarction and stroke. A prolonged period of hypoglycemia can provoke macroangiopathy, polyneuropathy, nephropathy, retinopathy. The study is necessarily assigned to women with diabetes during pregnancy planning (approximately 2-6 months before the expected conception).

Blood for glycated hemoglobin must be donated when characteristic symptoms of diabetes appear.Glycated hemoglobin. The norm in women by age. table

These include:

  • partial loss of visual acuity;
  • polyuria;
  • intense thirst;
  • dry mouth.

Also, the analysis is prescribed to patients suffering from diseases of the skin of an inflammatory-purulent nature (pyoderma, furunculosis).

Women over 40 should regularly donate blood for hemoglobin. This will allow timely identification of predisposition to diabetes and diabetes.

If glycated hemoglobin is monitored regularly, then the likelihood of timely diagnosis of pathologies such as encephalopathy and microangiopathy increases.

Preparation and delivery of analysis

The analysis for glycated hemoglobin does not require special preparation. It is enough to visit the laboratory in the morning and donate blood on an empty stomach. The biomaterial is taken from the index finger or vein. During the blood collection process, the laboratory technician can use a vacuum container or a sterile disposable syringe.

High-speed, compact analyzers suitable for home use are available from pharmacies. Due to their high cost, analyzers are not popular among the population.

In the laboratory, several basic methods of studying biomaterial for glycated hemoglobin are used in practice:

  • colorimetric method;
  • liquid high performance chromatography;
  • immunoturbidimetric method;
  • capillary electrophoresis;
  • cathine exchange chromatography.Glycated hemoglobin. The norm in women by age. table

Capillary electrophoresis is the most informative and cheapest method for the determination of glycated hemoglobin. The standard form hba1c contains fructose. Phosphoric acid must be added to the test tube with biomaterial. The mixture is thoroughly stirred and placed under a spectrophotometer. Through simple mathematical calculations, the laboratory assistant identifies the indicator of glycated hemoglobin. The results are given to patients on time.

What can affect the results

Glycated hemoglobin (the norm in women is determined individually) is a blood component. Nothing can influence the results of the analysis. If the laboratory assistant conducted the study correctly, then the indicators will be as accurate as possible regardless of what the patient ate, whether he used alcohol and tobacco products. Despite this, experts advise to refrain from drinking alcoholic beverages at least 24 hours in advance. prior to the proposed study.

Interpretation of research results

Optimal indicators are not less than 4.2% and not more than 6%. In this case, the patient has no predisposition to diabetes. If the laboratory form contains 5.6-6.4%, then there is a high risk of developing disorders of the body's tolerance to glucose. In this case, the Patient is tentatively diagnosed with prediabetes. At 6.5%, the diagnosis of diabetes is 90% likely to be confirmed.

Causes of high glycated hemoglobin

Overestimated levels of glycated hemoglobin will be in people with diabetes. An increase in values ​​is possible with iron deficiency anemia. In people who donated blood during the rehabilitation period after splenectomy, the results may be false. In this case, it is necessary to re-pass the analysis after 1-2 months.

Low level reasons

The main reasons for the decrease in the values ​​of glycated hemoglobin are considered hemolytic anemia and hypoglycemia. Indicators may change after blood transfusion. If a patient suffering from diabetes mellitus receives effective medication during the period of blood donation for hemoglobin, then his indicators will be underestimated.

How to lower your glycated hemoglobin count

Increased glycated hemoglobin is often found in overweight people. Experts recommend first of all to get rid of those extra pounds. To do this, you must lead a healthy lifestyle and exercise regularly. Doctors also recommend that you completely stop drinking alcohol and tobacco.

Preventive measures for prediabetes include diet. This is one of the most effective ways to bring glycated hemoglobin indicators back to normal. Patients with diabetes mellitus may be prescribed special medications.

Diet

In case of violation of the body's tolerance to glucose, patients are shown a diet. In the absence of excess weight per day, it is recommended to consume no more than 300 g of carbohydrates, which should enter the stomach along with vegetables and cereals. If a person is overweight, then the amount of complex carbohydrates is reduced to 110-120 g. It is necessary to regularly arrange fasting days (at least 2 times a week).

Diet food implies a complete rejection of foods containing the so-called "quickly digestible" carbohydrates.

These include:

  • pasta;
  • sweet syrups;
  • white wheat bread;
  • ice cream;

Wheat bread must be replaced with whole grain or rye bread. The daily norm is no more than 250 g. The basis of the diet is made up of fruits, vegetables, lean meat and fish. They can be boiled, baked, stewed and sautéed with the addition of a small amount of vegetable oil.

Soups, borscht, cabbage soup and other first courses must be cooked in vegetable or mushroom broth. To satisfy the body's need for protein, fermented milk products are included in the diet. Natural honey is used as a dessert (no more than 2 tsp. l. in a day). Products for diabetics (waffles, sweets, crackers) can be consumed no more than 2 times a week.

Fresh herbs and natural spices are used to improve the taste of the first and second courses. Small amounts of butter can be added to soups, borscht, hodgepodge.

To lower glycated hemoglobin levels, you must completely abandon sweet desserts, drinks, pastries, sausages, ready-made sauces, smoked meats, fatty fish and meat, canned food, spicy, salty food.

Should be excluded from the diet:

  • seafood and fish - cod liver, sardines in oil, smoked fish, river bass, halibut, salmon, flounder, squid, caviar, carp, bream;

  • fruits and vegetables - mango, melon, banana, pomegranate, feijoa, snake fruit, pineapple, plum, peach, cherry plum, beetroot, potatoes, carrots, tomatoes, horseradish.

One of the main principles of a diet aimed at reducing glycated hemoglobin is adherence to the drinking regime.

During the day, the following drinks are allowed:

  • freshly squeezed apple, pumpkin, tomato, plum juice (diluted with water in a ratio of 1: 1);
  • black tea without sugar;
  • coffee;
  • chicory drink;
  • pure boiled or mineral water.

Alcoholic, energy, sweet carbonated drinks are prohibited during the diet.

Drugs

People with diabetes can take drugs to lower hemoglobin with the permission of their doctor.

After a complete examination, the specialist can include the following drugs in the drug therapy:

  • Gliclazide. The drug is marketed in pill form. The active ingredient is gliclazide (no more than 5 mg). The drug belongs to a group of potential glycemic regulators. The tablets are taken 2 times a day. The daily dose is not more than 20 mg, which is equivalent to 4 tablets. The drug initiates the process of insulin synthesis.Glycated hemoglobin. The norm in women by age. table
  • Glickvidone. The drug belongs to the group of synthetic sulfonylurea derivatives. The drug is prescribed for diabetics suffering from renal failure. Gliquidone is able to control glycemia, minimizing the risk of developing prolonged hypoglycemia.
  • Diabetone. The active ingredient is gliclazide (no more than 80 mg). The drug reduces the level of glycated hemoglobin, having a positive effect on the hemostatic system. According to reviews, the drug improves the rheological properties of blood. The drug is highly bioavailable. The drug form is tablets. You need to take them 1 time (preferably in the morning before breakfast).

The therapy is selected individually. The course and regimen of taking a particular drug directly depends on the patient's well-being, his age and diagnosis.

How often should blood be donated for glycated hemoglobin

For people with diabetes, experts recommend donating blood for glycated hemoglobin at least 3-4 times a year. The analysis is able to reveal the dynamics of the increase in indicators depending on certain factors (nutrition, stressful situations).

Healthy women need to donate blood for glycated hemoglobin 1-2 times a year. 3 months before the intended conception, the obstetrician-gynecologist must send the patient to the laboratory.

Why test glycated hemoglobin when you can simply measure blood sugar?

The concentration of sugar in the blood is a variable quantity. Indicators can change several times per day. Glycated hemoglobin allows early detection of diabetes mellitus. The blood test also helps to identify possible fluctuations in glucose over the past 3 months. Based on the results, the specialist selects an adequate diabetes treatment regimen.

Glycated hemoglobin is a protein that correlates glucose levels in the body. Deviations from the norm in women indicate either the development of diabetes mellitus or pregnancy. To confirm diabetes, you must undergo a complete medical examination.
