Clinical significance:
Used to detect fetal hemoglobin (hemoglobin F) and dose Rh immunoglobulin in Rh negative women with a positive fetal hemoglobin screen. Elevated hemoglobin F levels occur from fetomaternal hemorrhage, hemoglobinopathies (sickle cell disease, hereditary persistence of hemoglobin F, etc.) or in patients taking medications that increase hemoglobin F production (hydroxyurea, etc.).
