Using PCV 46% and Total RBC count 8 x 10^6/µL, what is the MCV?

Explanation:
Mean corpuscular volume shows the average size of red blood cells and is calculated from hematocrit and RBC count using MCV = (Hct × 10) / RBC (in millions/µL). With a PCV (Hct) of 46% and an RBC count of 8 x 10^6/µL, MCV = (46 × 10) / 8 = 460 / 8 = 57.5 fL. So the MCV is 57.5 femtoliters. This value is well below the normal range, indicating microcytosis.
