What is Corpuscular Hemoglobin Concentration Mean (CHCM)?

CHCM (Corpuscular Hemoglobin Concentration Mean) measures the average concentration of hemoglobin within your red blood cells. It tells you how densely packed each cell is with hemoglobin, the protein responsible for carrying oxygen.

Unlike the traditional MCHC (which is calculated from total hemoglobin divided by hematocrit), CHCM is directly measured by shining a laser through intact red blood cells. This optical measurement makes it more accurate, especially when samples contain interfering substances like lipids or free hemoglobin from broken cells.

CHCM is reported as part of a complete blood count (CBC) on analyzers that support direct optical measurement. A normal range is typically 32–36 g/dL.

Where Does Corpuscular Hemoglobin Concentration Mean (CHCM) Come From?

Hemoglobin is produced inside developing red blood cells in the bone marrow. The concentration of hemoglobin per cell depends on adequate iron supply, functional hemoglobin genes, and normal red cell membrane structure.
