Final answer:
Glycosolated hemoglobin, or HbA1c, is a measurement of the amount of glucose that has entered red blood cells over their lifespan. It is used to monitor the long-term control of diabetes mellitus.
Step-by-step explanation:
Glycosolated hemoglobin, also known as glycosylated or glucosylated hemoglobin (HbA1c), is a measurement of the amount of glucose that has entered the red blood cells (RBC) over the lifespan of the cell. HbA1c is formed when glucose attaches to the hemoglobin molecule in the RBC. This measurement is important for monitoring the long-term control of diabetes mellitus.
