Which formula calculates MCHC?

Which formula calculates MCHC?

• A. Hb (g/dl) x 10 / PCV%
• B. Hb (g/dl) x 50 / PCV%
• C. Hb (g/dl) x 100 / PCV%
• D. PCV% x Hb

Answer: (C)

Mean corpuscular hemoglobin concentration shows how much hemoglobin is packed into each red blood cell. It’s calculated using the hemoglobin concentration and the packed cell volume, with the standard formula being Hb (g/dL) × 100 ÷ PCV (%). This yields a concentration in g/dL, reflecting how densely hemoglobin fills the cells. For example, if Hb is 15 g/dL and PCV is 45%, MCHC = 15 × 100 ÷ 45 = 33.3 g/dL. The other ways of calculating mix in different multipliers or multiply Hb by PCV%, which don’t produce a true concentration per cell volume and thus aren’t correct.
