It is normal: Hemoglobin is the molecule in red blood cells that carries oxygen, and it exists in several different forms. Hemogloobin f, or fetal hemoglobin, is what we have before birth, and gradually it is replaced with hemoglobin a. Usually 98% of our hemoglobin is hemoglobin a1, and a small percentage is hemoglobin a2. In some blood diseases, these percentages change.Your test shows no hemoglobinopathy.
