Why This Biomarker Matters

Elevated hemoglobin F in adults indicates genetic blood disorders or bone marrow disease that may require specialized treatment and genetic counseling.

Overview

Hemoglobin F (fetal hemoglobin) is normally present in high amounts before birth but decreases after birth as adult hemoglobin takes over. In adults, elevated hemoglobin F can indicate inherited blood disorders like sickle cell disease, thalassemia, or hereditary persistence of fetal hemoglobin. It can also be elevated in conditions causing bone marrow stress or hemolytic anemia. This qualitative test detects the presence of hemoglobin F and helps diagnose genetic blood disorders.
