How does fetal hemoglobin help sickle cell
WebFetal hemoglobin protects newborns from the effects of sickle hemoglobin. As people age, the amount of fetal hemoglobin decreases and complications begin. Increasing fetal hemoglobin levels reduces clumping of sickle hemoglobin and helps keep your red blood cells round and flexible. 2,3 WebHemoglobin (Hgb) F, fetal hemoglobin. This type of hemoglobin is found in unborn babies and newborns. HgbF is replaced by HgbA shortly after birth. If levels of HgbA or HgbF are too high or too low, it can indicate certain types of anemia. Abnormal types of hemoglobin include: Hemoglobin (Hgb) S.
