Description
The Sickle Cell Screen is a qualitative screening test for the detection of hemoglobin S in blood samples. The test is used for the diagnosis of Sickle cell disease in conjunction with other criteria. A hematocrit is run concurrently. Hemoglobin electrophoresis is automatically ordered to confirm positive sickle results.
False negatives may occur due to fetal hemoglobin; this test should not be performed on children under the age of 6 months. Suggest hemoglobin electrophoresis instead. This test is not for patients known to have Sickle cell disease.
