Mean Corpuscular Hemoglobin Concentration (MCHC) Measure

A Mean Corpuscular Hemoglobin Concentration (MCHC) Measure is a measure of concentration for haemoglobin in a given volume of packed red blood cell.

• Context:
  • It can produce a MCHC Value (it ranges from being macrocytic (high), to being microcytic (low).
  • …
• Example(s):
  • 31.9 (2020-09)
  • 33.1 (2019-11).

  • The mean corpuscular hemoglobin concentration (MCHC) is a measure of the concentration of haemoglobin in a given volume of packed red blood cell.

    It is calculated by dividing the haemoglobin by the haematocrit. Reference ranges for blood tests are 32 to 36 g/dL (320 to 360g/L), or between 4.81 and 5.58 mmol/L. It is thus a mass or molar concentration. Still, many instances measure MCHC in percentage (%), as if it were a mass fraction (m_Hb / m_RBC). Numerically, however, the MCHC in g/dL and the mass fraction of haemoglobin in red blood cells in % are identical, assuming an RBC density of 1g/mL and negligible haemoglobin in plasma.
