Fetal Hemoglobin (Definition)

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

Is hemoglobin test significant to determine iron deficiency in a patient?

Is hemoglobin test significant to determine iron deficiency in a patient?

No: Hemoglobin level determines if u r anemic. However, simplified, the size of red blood cells (rbc) can be small and mean iron deficiency, or large and mean Folic Acid or B12 deficiency. Causes of iron deficiency is loss of blood (iron molecule is in the rbc), without there being a store of iron in the body for the bone marrow to make more of them. Must be treated.

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?

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

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 worried should I be about an abnormal hemoglobin test resul that has to be retested?

How worried should I be about an abnormal hemoglobin test resul that has to be retested?

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

Why might I need a glycosylated hemoglobin test?

Why might I need a glycosylated hemoglobin test?

Sweetness : Aka hemoglobin a1c, is the most specific and sensitive test widely available to detect not only diabetes, but also how well or not controlled it is. There are other research level labs being looked at, a we are trying to figure out as early as possible who is pre diabetic, so we can aggressively go after your risks. Diet, exercise, are still the mainstay of treatment. Fda has not approved meds. ...Read more
