User avatar Hello,In an adult persisting foetal haemoglobin is seen in certain communities like greeks and black.This is supposed to be due to a genetic mutation.This condition known as Hereditary persistence of foetal haemoglobin HPFH is asymptomatic and would not cause any problems.In foetal life up to 6months 75% and in adults up to 2% of foetal Hb is seen.Thalasemias,anaemias,Hemoglobinopathies,and certain malignancies also show increase in foetal Hb.You may have a false abnormal if you have received transfusions in 12weeks.Do consult a haematologist for further evaluation.Best wishes.
