This test is used to detect a defective form of hemoglobin called hemoglobin Hb. It is responsible for sickle cell anemia.

Individuals with one sickle cell gene have a relatively small percentage of hemoglobin Hb. Individuals with two sickle cell genes have sickle cell anemia identified by a much larger concentration of defective hemoglobin. This test will determine the hemoglobin Hb levels in your body.
