Questions and Answers

What is the formula for Mean Cell Volume (MCV)?

MCV = Hct (%) × 10 / RBC (correct)

MCV = RBC × 10 / Hct (%)

MCV = Hgb (g/dL) × 100 / Hct (%)

MCV = Hgb (g/dL) × 10 / RBC

Mean Cell Hemolysis

Mean Cell Hematocrit

Mean Cell Hematoma

Study Notes

Mean Cell Volume (MCV)

Formula: MCV = (Hematocrit x 1000) / Red Blood Cell Count
Reference range: 80-100 fL
Increase in MCV can be due to: • Macrocytic anemia • Vitamin deficiency (B12 or folate) • Liver disease

Mean Cell Hemoglobin (MCH)

Unit of expression: Picograms (pg)
Associated with: Macrocytic anemia
MCH stands for Mean Cell Hemoglobin

Mean Cell Hemoglobin Concentration (MCHC)

Unit of expression: Grams per deciliter (g/dL)
Formula: MCHC = (Hemoglobin x 100) / Hematocrit
Corrective action if MCHC is: • Above 38 g/dL: Evaluate for polycythemia or dehydration • Below 32 g/dL: Evaluate for anemia or iron deficiency
