Hemoglobin S Evaluation with Reflex to RBC Solubility
Also known as: SCKLHB
Use
This test is used to determine the presence of hemoglobin S, and is recommended for detecting sickle cell trait in athletes. The test uses High Performance Liquid Chromatography (HPLC) to identify the presence of hemoglobin S, and if detected, it is confirmed with RBC solubility testing. The test helps differentiate hemoglobin S from other abnormal hemoglobin variants.
Special Instructions
Not provided.
Limitations
This test does not differentiate hemoglobin S trait from homozygous sickle cell disease or other combinations such as S/C, S/D, S/G, S/E, S/thalassemia, S/O-Arab, S/New York, and C-Georgetown trait (Hb C-Harlem). For a more detailed evaluation, additional testing methods like electrophoresis might be necessary.
