Ordinarily performed on patients over one year old.

This assay quantitates Hemoglobin A, A2, C, F, and S levels using capillary electrophoresis. If a rapid screen for the presence of sickle hemoglobin is clinically indicated, then "Sickle Cell Screen" [LAB339] would be the appropriate order. For fetal erythrocyte quantitation in maternal blood (e.g., workup of possible feto-maternal hemorrhage), "Fetal Erythrocyte Quantitation" (LAB292) would be the appropriate order.

Methodology:

Capillary Electrophoresis
