HbA1C

Description

A hemoglobin A1C (HbA1C) test is a blood test that shows what your average blood sugar (glucose) level was over the past two to three months.

Glucose is a type of sugar in your blood that comes from the foods you eat. Your cells use glucose for energy. A hormone called insulin helps glucose get into your cells. If you have diabetes your body doesn’t make enough insulin, or your cells don’t use it well. As a result, glucose can’t get into your cells, so your blood sugar levels increase.
