Description of Cell Volume

Mean Cell Volume (MCV) describes the total amount of red blood cells you have in your body. Doctors generally do a blood work test to observe your MCV in order to check for various types of anemia.

  1. Functions of MCV

    • The purpose of the MCV is to determine the size of a person's red blood cells. Red blood cells transport hemoglobin which transports oxygen; the amount of oxygen carried is dependent on the hemoglobin and the red blood cells. Abnormally high or low levels of MCV are signs of anemia. The median range for MCV is 86 to 98 femtoliters.

    MCV Calculation

    • MCV was traditionally a calculated parameter MCV = [Hematocrit (volume of packed red cells) X 10]/RBC in millions/cu.mm. In modern day, machines such as the Advia offer a more precise way to calculate MCV.

    MCV Abnormalities

    • When your MCV number is slightly higher than the optimal range, you are considered to have macrocytic anemia. This is caused by a vitamin B12 or B6 deficiency, alcoholism, folic acid deficiency or absorption problems. A lower than preferred MCV level is called microcytic anemia. This type of anemia may cause bleeding ulcers or other bleeding issues. Microcytic anemia is caused by an iron deficiency, vitamin B6 deficiency or gastrointestinal malabsorption problems.
