When the average amount of hemoglobin per red blood cell is decreased, then the concentration is decreased. So, when the MCV is decreased, the MCHC is decreased. Increases in the MCHC are limited by the amount of hemoglobin that can fit inside a red blood cell.Severe burns or a disorder called hereditary spherocytosis can cause high MCHC values.hen MCV values are normal, the red blood cells are normal in size. They are called normocytic. However, a person with normocytic red blood cells can still be anemic when there are too few red blood cells or when other RBC indices are abnormal. This is called normocytic anemia.
severe form of hypothyroidism, can cause high MCV levels as well. Another condition that can cause an increased MCV level is myelofibrosis, in which the normal bone. marrow (a type of tissue inside of the bones) is replaced by fibrous tissue (the connective tissue of the. body).
