Given Hct 0.400 L/L, Hgb 150 g/L, RBC 4.00 x 10^12/L, what is the MCH?

MCH is the average amount of hemoglobin per red blood cell. To calculate it, use compatible units for hemoglobin concentration and red cell count. Convert the given values: 150 g/L is 15 g/dL, and 4.00 x 10^12/L is 4.00 x 10^6/µL (millions per microliter). Then apply MCH = (Hgb in g/dL) × 10 ÷ (RBC in 10^6/µL). So MCH = 15 × 10 ÷ 4 = 150 ÷ 4 = 37.5 pg. The resulting MCH is 37.5 picograms.
