3.2.2. HGB Measurement
During the analysis cycle, lysing reagent is released into the Dilution chamber. This reagent
breaks down the RBC cell membrane and releases the Hemoglobin within the cell. The hemo-
globin, released by the lysing reagent, combines with the Potassium cyanide from the lysing
reagent to form a chromogenous cyanmethemoglobin compound. This compound is then mea-
sured through the optical part of the first dilution chamber by way of spectrophotometry at
a wavelength of 550nm.
