Fetal Hemoglobin (Overview)

Is the main hemoglobin that transport oxygen in the fetus during the last seven months of development in the uterus and in the newborn until roughly 6 months old., fetal hemoglobin is able to bind oxygen with greater affinity than the adult hemoglobin, giving the developing fetus better access to oxygen from the mother's bloodstream.

Some adults with sickle cell anemia have high levels of fetal hemoglobin. Any reason for this?

Some adults with sickle cell anemia have high levels of fetal hemoglobin. Any reason for this?

Epigenetics and drug: We know that sickle cell patients that have increased Hemoglobin F typically have less sickle cell complications. This is the basis for using Hydroxyurea in sickle cell patients. Some individuals have elevated Hemoglobin F levels due to differences in the genetic region of the beta and gamma globin genes that prevent the normal shutting-off of the gamma globin gene. This leads to increased HGB f. ...Read more

How common is the inherited persistence of fetal hemoglobin?

Difficult to measure: This is difficult to measure because in most people with inherited persistence of fetal hemoglobin are entirely asymptomatic. However, population studies have shown that about 10% of the population has been seen to have some persistence of fetal hemoglobin but in varying levels (from 0.8% of cells containing the fetal hemoglobin up to about 10% fetal hemoglobin levels). ...Read more

I have elevated levels of fetal hemoglobin. What can cause this? I am not pregnant. Does it point to a disorder?

Not necessarily: Elevated fetal hemoglobin may represent what is known as persistence of fetal hemoglobin. It would be helpful to know what the percentages of various hemoglobins are in your electrophoresis, This may be normal for YOU or it could represent a topic which needs investigation. Please speak to your doctor. Good luck! ...Read more

Also check for sources of bleeding such as from the gut. Stop iron once corrected. ...Read more
