Hemoglobin Barts (γ 4) – A variant form of hemoglobin, formed by a tetramer of γ chains, which may be present in variants of α thalassemia. Hemoglobin S (α 2 β S 2) – A variant form of hemoglobin found in people with sickle cell disease. There is a variation in the β-chain gene, causing a change in the properties of hemoglobin, which ...
The normal hemoglobin types are Hemoglobin A (HbA), which makes up 95–98% of total hemoglobin in adults, Hemoglobin A2 (HbA2), which constitutes 2–3% of total hemoglobin in adults, and Hemoglobin F (HbF), which is the predominant hemoglobin in the fetus during pregnancy, and may persist in small amounts in adults.

[2] Abnormal value of hemoglobin does not necessarily indicate a medical problem needing treatment. [3] Diet, activity level, medications, a women's menstrual cycle, and other considerations can affect the results. [3] Additionally to these, one may have higher than normal hemoglobin if they live in a high altitude area. [3]
MCH=(Hb*10)/RBC (in millions) [3] A normal MCH value in humans is 27 to 33 picograms (pg)/cell. The amount of hemoglobin per RBC depends on hemoglobin synthesis and the size of the RBC. [4] The mass of the red cell is determined by the iron (as part of the hemoglobin molecule), thus MCH in picograms is roughly the mass of one red cell.

A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
