The principle that relies on detecting resistance as cells pass through a photo-detector and is used by most of the major hematology analyzers is:
A) Spectrophotometry
B) Impedance
C) Radio frequency
D) MAPSS technology

Question

Quizplus · Accepted Answer

The principle that relies on detecting resistance as cells pass through a photo-detector is called impedance, and it is the most commonly used technology in modern hematology analyzers. Spectrophotometry involves analyzing the absorption or transmission of light by a substance, and it is not typically used for cell counting or differentiation. Radio frequency and MAPSS technology are not commonly used in hematology analyzers.
