Question

Quizplus · Accepted Answer

A midstream clean-catch specimen is a method used to minimize contamination from the external genitalia. Squamous epithelial cells, which are common contaminants from the skin and external urethra, are significantly reduced in number with this technique. The other options (renal tubular epithelial cells, RBCs, and transitional epithelial cells) are not specifically targeted by the clean-catch method for reduction, as they can originate from within the urinary tract itself.
