What is Aha hemoglobin A1c test?​

A hemoglobin A1c (HbA1c) test measures the amount of blood sugar (glucose) attached to hemoglobin. Hemoglobin is the part of your red blood cells that carries oxygen from your lungs to the rest of your body. An HbA1c test shows what the average amount of glucose attached to hemoglobin has been over the past three months.

What does an A1C of 5 0 mean?​

An A1c of 5.0 means that 5.0% of the hemoglobin in your blood are saturated with sugar. A1c 5.0 conversion rates Blood sugar can be measured in a variety of ways, which often leads to confusion. An A1c of 5.0 is equal to blood sugar of 97 mg/dl or 5.4 mmol/l.
What is A1c conversion to mmol/L?
Blood sugar can be measured in a variety of ways, which often leads to confusion. An A1c of 5.0 is equal to blood sugar of 97 mg/dl or 5.4 mmol/l. View the full A1c conversion chart to better understand these tests and numbers.

What is the relationship between glucose and hemoglobin A1c?​

The sugar in your blood is called glucose. When glucose builds up in your blood, it binds to the hemoglobin in your red blood cells. The A1c test measures how much glucose is bound.

What does it mean when your A1c level is high?​

The more glucose in your blood, and the longer it stays elevated, the more it will attach to the hemoglobin. The A1C test result is reported as a percentage. The higher the percentage, the higher your blood glucose levels. A normal A1C level is below 5.7 percent.
Can hemoglobin variants give false A1c readings?
In the second post of our Interpreting A1C blog series, Randie R. Little, PhD, discusses how hemoglobin variants can give falsely high or low readings with A1C testing methods, and how this can lead to the over-treatment or under-treatment of diabetes.

How long do hemoglobin and hemoglobin A1c last?​

However, it is limited to three months of time as the lifespan of red blood cell is around 120 days. Hemoglobin and hemoglobin A1c are two types of globular hemoproteins. Both contain the tightly bound prosthetic group known as heme. Also, both occur in red blood cells.
