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
