A hemoglobin electrophoresis test is a
blood test done to check the different types of
hemoglobin in the blood. Results are ready in several
The normal values listed here—called a reference range—are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.
96.5%–98.5% of total
hemoglobin or 0.96–0.985 mass fraction
1.5%–3.5% of total
hemoglobin or 0.015–0.035 mass fraction
0%–1% of total
hemoglobin or 0–0.01 mass fraction
High and low values
Higher-than-normal amounts of both hemoglobin
hemoglobin F may mean a mild form of
thalassemia is present. A very low level of hemoglobin
A and a high level of hemoglobin F may mean a more severe form of thalassemia.
High levels of hemoglobin F may be seen in a rare condition called hereditary
persistence of fetal hemoglobin.
