Indices
The red cell indices MCH and MCHC are derived from the mathematical
calculation of the RBC count, the total hemoglobin, and the MCV determination.
The HCT value is calculated from the RBC count and the MCV.
The RDW and HDW values are calculated from the cell-by-cell measurement of
cell volume and hemoglobin concentration.
The CH represents the mean of the cell hemoglobin content histogram.
The CHCM is calculated as the mean of the RBC hemoglobin concentration
histogram.
