The technique that should be performed to differentiate starch particles from pathogenic crystals in fluids is:
A) Examination with polarized light
B) Examination with fluorescent light
C) Examination with Wright stain
D) Calculation of RBC to WBC ratio

Question

Quizplus · Accepted Answer

Examination with polarized light is the best technique to differentiate starch particles from pathogenic crystals in fluids. Starch particles rotate polarized light in a circular pattern, while pathogenic crystals do not have this effect. Therefore, starch particles will exhibit characteristic cross-polarization under a microscope, making it easy to differentiate them from pathogenic crystals.
