Question

MCV (in fl) = [(actual hematocrit % x 10⁷) / RBC count per mm³ blood)

The normal human adult MCV ranges from 82-92 fl

MCHC = [(Hb in g/dL x 100) / Hematocrit %)

The average normal adult human MCHC is 32-36

A female patient has a RBC count of 5 x 106/mm3 blood, 37% Hct, and Hb concentration of 13 g/dl blood. Does she person exhibit anemia? (be sure to show any calculations)

Answer 1

Hematocrit (Hct) = 37%.

RBC count per mm³ blood = 5 ×10⁶

Hb concentration = 13 g/dl

So, MCV = actual hematocrit ×10⁷/ RBC count per mm³ blood =(37×10⁷)/(5× 10⁶) = (37× 10)/5 = 37×2 = 74 fl.

MCHC =Hb in g/dl × 100/ hematocrit =(13×100)/ 37 = 35.13

Now the results showing, MCV has reduced & MCHC is in normal range.

As MCHC has reduced it gives idea about microcytic anemia which seen in iron deficiency anemia , thalassemia.

So, the patient is exhibiting anemia.
