HbA1c
HbA1c (pronounced as H-B-A-one-C), also known as glycated hemoglobin, is a form of hemoglobin that is chemically linked to a sugar. The abbreviation HbA1c is derived from Hemoglobin, type A, subtype 1c.
Etymology
The term "HbA1c" is an abbreviation where 'Hb' stands for Hemoglobin, 'A' refers to the type of hemoglobin, and '1c' is the subtype. The 'A1c' part of the term refers to the glycated form of hemoglobin, indicating that the hemoglobin molecule has a sugar attached to it.
