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 ...Read more
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 moreSee 1 more doctor answer
Hb F: 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. ...Read more
I have elevated levels of fetal hemoglobin. What can cause this? I am not pregnant. Does it point to a disorder?

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
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
Varies: There are in excess of several hundred recorded mutations in the hemoglobin molecules & some are little more than a curiosity and some (sickle cell) could have significant implications.The screening process just selects those who need to be looked at more closely. I would not spend a lot of emotional energy at this point. Get more facts first. ...Read more
