Yes, there are HbA1a, HbA1b, as well as HbA1c. The coding breakdown is given below.

When hemoglobin is exposed to higher than normal levels of glucose over time (blood sugar) it binds with it, this is called glycation. And since the normal life span of red blood cells is about 120 days, glycated hemoglobin can be used to assess the average level of blood sugar during the preceding three months of the test.

Hb - Hemoglobin

HbA - Adult hemogolbin (as contrasted to fetal hemoglobin, HbF)

HbA0 - non-glycated hemoglobin.

HbA1 - glycated hemoglobin

HbA1a1 - Glycation with Fructose 1, 6 diphosphate

HbA1a2 - Glycation with Glucose 6 phosphate

HbA1b - Glycation with an unknown reaction partner

HbA1c - Glycation with D glucose

L HbA1c - denotes the labile HbA1c, or the aldimine fraction

S HbA1c - denotes the stable HbA1c, or the ketoamine fraction.

There is no separate HbA1a or HbA1b; HbA1c refers to glycated hemoglobin. HbA1c is a measure of the average blood glucose levels over the past 2-3 months and is used to monitor long-term blood sugar control in people with Diabetes. High levels of HbA1c indicate poor blood sugar control and an increased risk of diabetes complications.

What does the HBA1C test find?

The HbA1C test finds how much HbA1C is in your blood. A normal non-diabetic has about 3.5-5.5% HbA1C, but 6.5% is good for a diabetic. This is one of the best ways to check whether someone's diabetes is under control.


What colour blood tube for hba1c?

The color of the blood tube for HbA1c testing is typically lavender. Lavender-top tubes are used for collecting blood samples for hematology testing, including HbA1c.

What is a hba1cbloodtest?

HbA1c is commonly used in relation to diabetes. Act as indicator of diabetes control. People with diabetes this is important as the higher the HbA1c. By measuring glycated haemoglobin (HbA1c) you have an overall picture of what your average blood sugar levels have been over a period of time.


What does the medical abbreviation HbA1C mean?

HbA1c, or glycated hemoglobin, is a measure of blood sugar over time, during the last two or three months.


What color test tube is HbA1C?

HbA1C test tubes are typically light purple in color, signifying that the blood sample is for a chemistry test.

What is a H6A1C blood test?

The HbA1c blood test measures average blood glucose levels over the past 2-3 months. It is used to diagnose and monitor diabetes. A higher HbA1c level indicates poorer blood sugar control.


What is the cost of a HBA1C blood test?

The cost of an HbA1c blood test can vary depending on where it is done and if insurance is involved. Typically, the cost ranges from $20 to $50 without insurance. It is best to check with the specific lab or healthcare provider for an accurate cost.


What does the medical abbreviation A1c mean?

A1c is an abbreviation of another abbreviation, HbA1c, or hemoglobin A1c. It's a blood test that evaluates how your blood sugar levels have been over the last three months.HbA1c is a common measurement used when assessing diabetes. It stands for Hemoglobin A1-c. The A1c is simply a specific subtype of hemoglobin A. Hemoglobin is a molecule located in your red blood cells that is responsible for holding oxygen. HbA1c is formed when glucose (a blood sugar) binds to the hemoglobin. Ordinarily, it occurs slowly. Doctors check HbA1c levels as a way to assess the average blood sugar in a person for the past 2 months. If the HbA1c is above 6.5-7%, then the blood sugar is not adequately being controlled.


What does a fasting blood sugar level of 122 mean?

Yes. You can be diagnosed as diabetic. However, if this is a one off test, do not jump on to insulin straight away. First under go GTT (Glucose Tolerance Test) and HbA1C Test. HbA1C is considered to be more reliable test in determining whether a person is diabetic or not. When you consume more sugars on the previous day, the fasting test can not be taken as reliable. Therefore, before jumping onto insulin bandwagon, better consult a good diabetician with GTT and HbA1C Results.
