Distinguishing large deletional hereditary persistence of fetal hemoglobin from other conditions with increased percentage of fetal hemoglobin
|Test ID||Reporting Name||Available Separately||Always Performed|
|HBF||Hemoglobin F, B||Yes||No|
The percent of the patient’s hemoglobin F is very important to the clinical utility of this test. HBF / Hemoglobin F, Blood will be performed at an additional charge to determine if Hemoglobin F, Red Cell Distribution testing is warranted. If the hemoglobin F value from HBF / Hemoglobin F, Blood are normal for age or if value is <5% the HPFH / Hemoglobin F, Red Cell Distribution, Blood will not be performed. Samples with hemoglobin F (Hb F) levels >35% will be accepted but are discouraged due to decreased test specificity. For these markedly elevated Hb F levels, a hemoglobin electrophoresis profile with request for beta globin gene molecular testing for elevated Hb F levels is recommended.
