Explanation:
Detailed explanation-1: -MCV defines the size of the red blood cells and is expressed as femtoliters (10−15; fl) or as cubic microns (m3). The normal values for MCV are 87 ± 7 fl. MCH quantifies the amount of hemoglobin per red blood cell. The normal values for MCH are 29 ± 2 picograms (pg) per cell.
Detailed explanation-2: -Decreased MCV, MCH, and MCHC—microcytic, hypochromic anemia—most often caused by iron deficiency.
Detailed explanation-3: -For example, the MCV is low in iron deficiency anemia. In that case, you may need additional tests for iron deficiency. The MCV may also change in conditions such as liver disease or deficiency of vitamin B12 or folate.
