What is a blood test for controlling diabetes, or the A1C test?

The A1C test examines the average glucose and glucose levels in the past 3 months. This test is also performed to evaluate diabetes. This test is different from the usual blood glucose tests performed by diabetics. Glucose has the potential for binding to blood hemoglobin and, on the other hand, hemoglobin in blood cells has the ability to transport oxygen to the blood. So doing this test is based on this. In people with diabetes, due to high blood glucose levels, this connection between blood sugar and blood is more likely to show a higher percentage as a result of the A1C test.

What conditions make it necessary to carry out this experiment in people?
The result of the A1C test can help physicians to:

Detection of people in the pre-diabetic stage, in which case physicians will give advice on lifestyle and how to control their blood glucose, so that the pre-diabetic status of these people does not become type 2 diabetes.
Find People With Type 2 Diabetes.
Helping to control and evaluate diabetes and prevent complicated conditions.
Is A1C Testing In Pregnancy?
Most doctors make this test early in pregnancy for women to ensure that they do not have pre-diabetic status or uncontrolled type 2 diabetes in women. Since the test values ​​show a person's glucose level over the past 3 months, doing so early in pregnancy and the result will be indicative of the level of blood sugar before pregnancy. Oral Glucose Tolerance Test (OGTT) for gestational diabetes is usually performed between weeks 24 to 28 of gestation.

Can the A1C test differ in the diagnosis of common blood glucose?
Yes, in some people, the result of routine diabetes tests may be diabetes, while the A1C test is different. There is, of course, the possibility of a reverse state. In this case, the result of the A1C test indicates diabetes, while the usual glucose test is in contrast. This proves the necessity of repeating tests in individuals.

Individuals with different test results may be at an early stage of the disease. In such cases, repeat testing and testing for appropriate diagnosis will be helpful.

Reviewing the results of the A1C test:
A1C levels below 5.7% represent normal values
Our A1C levels range from 5.7 to 6.4 to indicate pre-diabetic status
A1C levels of 6.5 and above represent diabetes
The A1C test should not be used to diagnose type 1 diabetes, gestational diabetes, or fibrosis-related diabetes. Having pre-diabetes will increase the risk of type 2 diabetes. Therefore control of these conditions is very important.

What conditions can affect the A1C test results?
The probability of misleading and unreliable results is in people with special circumstances. Conditions that change the life span of red blood cells include:

Loss of blood
Anemia or anemia of sickle cells
Anemia caused by vitamin B12 deficiency
Thalassemia
Treatment with erythropoietin hormone
Hemodialysis or receiving blood
The result of the A1C test can be incorrectly highlighted by the following factors
People with iron deficiency found in people with anemia due to iron deficiency
Kidney failure
Liver disease
When will the doctor prescribe this test to you?
This test may be part of a medical check-up, or your doctor may prescribe it if you have certain symptoms or if you are suspected of having diabetes. In addition to the above, this test is recommended for adults with high overweight and family history of diabetes, high blood pressure, cardiovascular disease, and those with high blood cholesterol, women with polycystic ovary syndrome and insulin resistance. .
