What Does Mean Corpuscular Volume (MCV) Mean?
Mean Corpuscular Volume (MCV) is the measure of the
average size of a patient's red blood cells. This evaluation forms part of the
Complete Blood Count test and is used as a differential to diagnose the cause of anemia in a
patient. Anemia is the result of a decrease in hemoglobin or blood cell count
and produces high or low Mean Corpuscular Volume measurements depending on the cause of the anemia.
WorkplaceTesting Explains Mean Corpuscular Volume (MCV)
In adults, Mean Corpuscular Volume measurements of
between 80 to 96 femtoliters are normal or normocytic. High, or large, average measurements
denote macrocytic red blood cells and are found in patients with liver disease,
folic acid and vitamin B12 deficiencies, as well as patients who are suffer from
alcoholism or are undergoing chemotherapy. Low, or small, average measurements
are deemed to be microcytic. Patients with microcytic red blood cells may
suffer from renal failure, iron deficiencies, or tumors in the gastrointestinal
tract or colon.
