Testing
Schedule:
This test is batched and run routinely on Fridays. If you need results
STAT, call Hematology resident (8-1630, M-F) at 356-8628. All other
times page the Pathology resident on-call at 3404.
Reference Range:
Hemoglobin A2 0-3.5% Hemoglobin C 0% Hemoglobin F Birth-3 months: 50-80% 3 months-1 Year: 6% After 1 year: 2% or less Hemoglobin S 0%
Comments:
Refer to BD Microtainer® Tubes product sheet for detailed sample collection
instructions.
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.
