If the person has one Hb S gene and one other abnormal gene, such as a Hb C gene, then the person will experience some of the same symptoms associated with sickle cell disease.

Hb S can form crystals that change the shape of the RBC from a round disc to a characteristic sickle shape.

No test preparation is needed; however, testing for diagnosis should not be performed after a recent blood transfusion.

Particularly in people with sickle cell disease, the relative amount of Hb S will be measured and followed over the course of treatment, for example, after a blood transfusion to ensure that the hemoglobin S level has been reduced.

The content on the site, which has been reviewed by laboratory scientists and other medical professionals, provides general explanations of what results might mean for each test listed on the site, such as what a high or low value might suggest to your healthcare practitioner about your health or medical condition. Typically, hemoglobin A (Hb A, hemoglobin) makes up most of the hemoglobin found in normal RBCs in adults, with small amounts of hemoglobin A2 and hemoglobin F. Before babies are born, they normally produce large amounts of hemoglobin F (Hb F, hemoglobin), which is then replaced by Hb A as the predominant hemoglobin shortly after birth. Sickle cell tests determine the presence and relative amount of hemoglobin S in a blood sample. Hemoglobin is a protein found in red blood cells (RBCs) that binds to oxygen in the lungs and carries it to tissues throughout the body.
