Hemoglobin Variants by Electrophoresis (Serum/Plasma)

Why This Test Is Done

Doctors may order this test if you have symptoms like fatigue, pain in bones or joints, or if family members have a history of blood disorders. It’s also used to screen for conditions like sickle cell trait or disease, especially in people of certain ethnic backgrounds.

How the Test Works

A small blood sample is taken and analyzed using electrophoresis, a method that separates hemoglobin variants based on their electrical charge. Different bands on the result indicate the presence of various hemoglobin types.

Sample Collection

Blood is drawn from a vein, usually in your arm, by a healthcare professional. You may feel a slight pinch, but it’s generally quick and not painful. You can eat or drink normally before the test.

What to Expect After the Test

After the blood draw, you’ll likely return to your regular activities immediately. There may be a small bruise or slight discomfort at the site, but it should resolve quickly. Results are typically available within a few days to a week, depending on lab processing times.
