Which haemoglobin type is found in healthy adults?

Explanation:
Haemoglobin A (HbA) is the type found in healthy adults. After birth, HbA becomes the predominant form, making up about 95–98% of circulating hemoglobin, with smaller amounts of HbA2 and only trace HbF. HbF is the fetal form and remains very low in adults. The other variants, HbS and HbC, are abnormal mutations associated with sickle cell disease or related traits, not with normal adult hemoglobin.
