11White Blood Cell Method
Coulter Principle
12Red Blood Cell Method
Coulter Principle
13Hemoglobin (HGB) Method
Photometric Measurement
14It is measured directly, multiplied by a calibration factor
White Blood Cell and Red Blood Cell (Coulter Method)
15It transmittance of light at 545 nm through lysed WBC bath, compared to the transmittance of the same light through a reagent blank. The system converts this ratio to the HGB value using a calibration factor
Hemoglobin (Photometric Measurement)
16Hematocrit Method
Calculated
17Hematocrit Calculation
HCT (%) = (RBC x MCV)/ 10
18Mean Corpuscular Volume (MCV) Method
Derived from RBC Histogram
19The average volume of individual RBC's derived from the RBC histogram, multiplied by a calibration factor
Mean Corpuscular Volume (MCV)
20Mean Corpuscular HGB (MCH) Method
Calculated
21Mean Corpuscular HGB (MXH) Calculation
MCH (pg) = (HGB/RBC) x 10
22Mean Corpuscular HGB Conc. (MCHC) Method
Calculated
23Mean Corpuscular HGB Conc. (MCHC) Calculation
MCHC (g/dL) = (HGB/HCT) x 100
