Clinical Medical Assistant Certification Exam Practice Question
Which of the following Is the portion of a centrifuged urine sample used for microscoplc examination?
Correct Answer: D
Rationale: In a centrifuged urine sample, the sediment is the portion that settles at the bottom and contains various elements, making it essential for microscopic examination. This sediment includes cells, casts, and crystals that provide valuable diagnostic information.
Artifacts (A) are remnants that do not originate from the urine itself and are not useful for analysis. Casts (B) and crystals (C) are specific components found within the sediment but do not represent the entire portion needed for examination. The supernatant (E) is the liquid layer above the sediment, which contains dissolved substances but lacks the solid elements necessary for a comprehensive microscopic evaluation.
