Reflex testing protocols add additional tests automatically based on initial findings, ensuring complete evaluation while avoiding unnecessary testing when initial results are normal. For urinalysis, microscopic examination is typically added when dipstick results show abnormal findings such as positive leukocyte esterase, nitrites, blood, or significant protein.
This protocol streamlines diagnostic workflow and ensures appropriate follow-up testing when initial findings warrant. Sample type depends on the original test (typically a clean-catch midstream urine for urinalysis).
