Cellular Hemoglobin Unit Converter

Cellular hemoglobin (CH) measures the average amount of hemoglobin contained in each red blood cell, expressed in picograms. It reflects how well your red blood cells are loaded with the oxygen-carrying protein they need to function.

Unlike the traditional MCH (mean corpuscular hemoglobin), which is calculated by dividing total hemoglobin by the red blood cell count, CH is directly measured on individual intact red blood cells using optical light scattering. This makes it less susceptible to certain laboratory interferences.

A normal CH typically falls between 24 and 35 picograms per cell.

Hemoglobin is synthesized in developing red blood cell precursors in the bone marrow, where iron is incorporated into heme and combined with globin protein chains. The final hemoglobin content of each mature red blood cell depends on adequate iron supply, functional heme synthesis enzymes, and normal globin gene expression.
