Hemoglobin A2/Hemoglobin total

Hemoglobin electrophoresis is a test that measures the different types of hemoglobin in the blood. It also checks for hemoglobinopathy, disorders involving abnormal types of hemoglobin. Hemoglobin is a protein in your red blood cells. It carries oxygen from your lungs to the rest of your body. There are a few different types of normal and abnormal hemoglobin.

Hemoglobin electrophoresis measures hemoglobin levels and looks for abnormal types of hemoglobin. If your hemoglobin type levels are too high or low, it could be a sign of a hemoglobin disorder. It's most often used to help diagnose anemia, sickle cell disease, and other hemoglobin disorders.
