If there is evidence of the sickle cell gene the tests will be repeated to confirm diagnosis (NIH). It is also possible to test the fetus for sickle cell anemia prior to birth through amniocentesis although this is not normally performed unless there is reason to believe the child will have sickle cell anemia due to the risk which this procedure presents to the fetus. Electrophoresis is performed on the blood to test for presence of the sickle cell gene as there are different patterns observed in those with sickle cell anemia than normal blood, as the hemoglobin present is Hb S. rather than the Hb a or Hb A2 which is usually present in normal adult erythrocytes or Hb F. which is usually present in fetal hemoglobin.

This would include analgesia for pain such as NSAIDs and iron replacement for the effects of the anemia, and in severe cases of the condition blood transfusions may be necessary (NIH). Folate supplements are also given to meet the increased needs for blood cell production. Many sufferers are also advised to undertake occupational therapy and physical therapy to help with pain management. Hydroxyurea is the first drug which has been shown to significantly prevent sickle cell crises, and is therefore indicated daily in treatment (SCIC)......
