To increase the probability of detecting urine sediment constituents that have a low refractive index,clinical laboratories often use:
A) Phase-contrast microscopy
B) Polarizing microscopy
C) Interference-contrast microscopy
D) Bright-field microscopy

Question

Quizplus · Accepted Answer

Phase-contrast microscopy is the best choice for increasing the probability of detecting urine sediment constituents that have a low refractive index. It enhances the contrast between light and dark parts of the sample, making it easier to identify low-contrast particles. The other microscopy techniques listed (polarizing, interference-contrast, and bright-field) are not optimized for this purpose and may not provide optimal results.
