More on the test...
The MCV Lab Test is a kind of Hemotology Test. The results are derived from Hct, Hgb, and RBC count from a blood sample. The test is an indicator for the size of the RBC's or red blood cells. It helps to determine if there is risk for certain anemia's.
Mean corpuscular volume (MCV) is a measurement of the average size of your RBCs (red blood cells). The MCV is elevated when your RBCs are larger than normal (macrocytic), for example in anemia caused by vitamin B12 deficiency. When the MCV is decreased, your RBCs are smaller than normal (microcytic), such as is seen in iron deficiency anemia or thalassemias.
Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average concentration of hemoglobin inside a red cell. Decreased MCHC values (hypochromia) are seen in conditions where the hemoglobin is abnormally diluted inside the red cells, such as in iron deficiency anemia and in thalassemia. Increased MCHC values (hyperchromia) are seen in conditions where the hemoglobin is abnormally concentrated inside the red cells, such as in burn patients and hereditary spherocytosis, a relatively rare congenital disorder.
