What is the hba1c and what does it measure?

Glucose metabolism. The hgba1c stands for glycosylated hemoglobin and measures the regulation of blood sugar over that past 90 days. It does not have to be drawn while fasting. It basically measures how Insulin resistant you are. Increased Insulin resistance results in an increase in blood sugar which raises glycosylated hemoglobin level. S your goal for hgba1c should be about 5.5.
