Specimen(s):
Blood
Collection Medium:
 |
| Lavender top tube 3 mL (EDTA) |
Minimum:
Full draw; 3.0 mL lavender top; (or fingerstick-purple top
microtainer®)
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:
This assay quantitates hemoglobin A, A2, C, F, and S levels using
capillary electrophoresis and includes pathologist interpretation of
hemoglobin electrophoresis pattern. This would be appropriate order
for initial workup of patient hemoglobin phenotype. If quantitative
Hb
A, A2, C, F, and S levels alone are sufficient, "Hemoglobin
Evaluation,
Quantitation Only" (LAB7798) would be appropriate order and would have
lower charges. For quantitation of fetal erythrocytes in maternal
blood (e.g., workup of possible feto-maternal hemorrhage), "Fetal
Erythrocyte Quantitation" (LAB292) would be appropriate order.
This test is appropriate for routine screening. Pertinent clinical information should accompany the request and there should be a recent hematology profile. Path resident will interact with clinician on all quantitative hemoglobin orders. Peripheral smear morphology, RBC indicies, and electrophoretic results are correlated by the pathologist and a written narrative is reported by computer. Analysis cannot be done on patients transfused within the preceding three months since the presence of transfused cells may render the interpretation ambiguous.
