Abstract
Apparatus and methods are described including measuring hematocrit within a blood sample, by performing a first measurement on a first portion of the blood sample. Mean corpuscular volume in the blood sample is measured, by performing a second measurement on a second portion of the blood sample, the second portion being diluted with respect to the first portion. A red blood cell count per unit volume within the blood sample is determined by dividing the hematocrit measured within the first portion by the mean corpuscular volume measured within the second portion. Other applications are also described.
