Note
This assay measures percentage of hemoglobin F only. If abnormal peaks suggestive of a hemoglobin variant are detected, then Capillary Electrophoresis will be added to aid in confirmation and identification of the variant. Additional charges apply. For complete hemoglobin evaluation, order Hemoglobin Evaluation with Reflex to Electrophoresis and/or RBC Solubility (0050610).
