The h/h blood group, also known as Oh or the Bombay blood group, is a rare blood type.This blood phenotype was first discovered in Bombay, now known as Mumbai, in India, by Dr. Y. M. Bhende in 1952.iosynthesis of the H and A and B antigens involves a series of enzymes (glycosyl transferases) that transfer monosaccharides. The resulting antigens are oligosaccharide chains, which are attached to lipids and proteins that are anchored in the red blood cell membrane.
Synonyms: Mean Cell Hemoglobin. Use: The MCH test measures the amount of hemoglobin in red blood cells and is another measure of cell size. The MCH test is used to determine the presence and cause of anemias, such as normochromic anemia or hyperchromic anemia. Limitations: An extremely elevated white blood cell count may cause an increased MCH value.
