Question

Diagnosis of sickle cell anemia is confirmed by which test?

1) Hemoglobin electrophoresis test
2) Complete blood count test
3) Liver function test
4) Kidney function test

Answer 1

Hemoglobin electrophoresis test is used to confirm the diagnosis of sickle cell anemia by identifying the presence of hemoglobin S in the blood.

Step-by-step explanation:

The diagnosis of sickle cell anemia is confirmed by a hemoglobin electrophoresis test. Sickle cell anemia is a genetic disorder characterized by the production of an abnormal type of hemoglobin called hemoglobin S.

This abnormal hemoglobin causes red blood cells to become sickle or crescent-shaped, especially in low oxygen environments.

These misshaped cells can block blood flow, leading to a host of complications. Hemoglobin electrophoresis is effective because it separates different types of hemoglobin based on their electrical charge differences. By running this test, medical professionals can identify the presence of hemoglobin S, which is indicative of sickle cell anemia.
