Hemoglobin electrophoresis is a test that measures the different types of hemoglobin in the blood. It also looks for abnormal types of hemoglobin. Normal types of hemoglobin include: Hemoglobin (Hgb) A, the most common type of hemoglobin in healthy adults.
A hemoglobin electrophoresis test applies an electric current to a blood sample. This separates normal and abnormal types of hemoglobin. Each type of hemoglobin can then be measured individually.
