The test of a person’s glycated hemoglobin (A1C), which reflects the average glucose concentration over the past 3 months, remains the best way to diagnose whether someone has diabetes or, after ...

What is hemoglobin A1c? This question came up in discussion with someone who had just had that blood test. It is the average of your daily blood sugar or glucose over the past 3 months or 8-12 ...

To shorten the name to just A1c is commonly done. It can go by other monikers like HbA1c, glycated (GLY-kated) or glycosylated hemoglobin, or glycohemoglobin. The prefix glyco- means sugar.

Excessive glucose molecules in the bloodstream can bind to hemoglobin and form what’s called glycated hemoglobin, or HbA1c. A hemoglobin A1c test measures the percentage of HbA1c present ...

After a diabetes diagnosis, A1C is also used for gauging how well treatment controls blood sugar levels. In the U.S., A1C results are given as a percentage of hemoglobin that is glycated.

Because A1C is done with a blood test, he said, it’s a “readily accessible marker that is inexpensive, and you can do it on a single blood draw any time of the day or night.” ...

The A1C test measures how much of the hemoglobin in a person's blood is "glycated" -- has glucose attached to it -- and it reflects the level of glucose circulating over the long term.

"A1C, or glycated hemoglobin, is a simple blood test that measures how much glucose binds to a red blood cell in three months, [which is] the life span of a red blood cell," says Dr. Peminda ...

The test can be used for the quantitative determination of percent glycated hemoglobin A1c (DCCT/NGSP) and mmol/mol hemoglobin A1c (IFCC) in human whole blood.
