Distinguishing large deletional hereditary persistence of fetal hemoglobin from other conditions with increased percentage of fetal hemoglobin

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

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.
