Hemoglobin (Hb), Fetal, Quantitative
Also known as: Fetal Hemoglobin, Hb F, Hemoglobin F Quantitation
Use
Evaluate hemoglobinopathies, hemolytic anemia; diagnose hereditary persistence of fetal hemoglobin; diagnose thalassemia; evaluate sickling hemoglobins
Special Instructions
Not provided.
Limitations
The test may not detect all forms of hemoglobinopathies and is primarily a quantitative assessment of fetal hemoglobin levels. It is not suitable for screening or diagnosing every possible abnormality. Conditions like erythroblastosis fetalis and anoxic states might alter the interpretation of Hb F levels. Variability in Hb F levels and its associated conditions may also pose interpretive challenges in some cases.
