HB. Electrophoresis

Specimen Required

3cc EDTA BLOOD (CBC VIAL)

Fasting Required

Purpose of the Test

HB (hemoglobin) electrophoresis is a test used to detect and identify different types of hemoglobin in the blood. This test is primarily used to diagnose or screen for certain blood disorders, such as sickle cell disease and thalassemia.

When this test is required

A healthcare provider may request an HB electrophoresis test if they suspect a patient has a blood disorder or if the patient has a family history of certain blood disorders. The test may also be performed as part of routine newborn screening or during pregnancy to assess the risk of a baby having a blood disorder.

What the Test Detects

HB electrophoresis is a laboratory test that separates the different types of hemoglobin in the blood based on their electrical charge and size. The test can identify abnormal hemoglobin types, such as hemoglobin S (found in sickle cell disease) or hemoglobin E (found in certain types of thalassemia).

Preparation for the Test

No specific test preparation is typically required for an HB electrophoresis test. However, a healthcare provider may advise a patient to fast or avoid certain medications before the test.

Sample Requirements

The sample required for an HB electrophoresis test is a blood sample. The blood is typically drawn from a vein in the arm.

Additional Notes

HB electrophoresis is a commonly used laboratory test that can provide valuable diagnostic information for certain blood disorders. It is a non-invasive test that typically does not require any specific preparation. However, it is important to discuss any concerns with a healthcare provider before undergoing the test.
