Use

Urinalysis with Reflex to Microscopic evaluates urine for chemical abnormalities via dipstick or macroscopic analysis and, if indicated by abnormal findings, proceeds to perform a microscopic examination to detect formed elements such as cells, casts, crystals, bacteria, and yeast — supporting diagnosis of urinary tract infections, metabolic or renal disorders.

Special Instructions

This test is a true reflex assay: microscopic examination is performed only when initial (macroscopic or dipstick) findings warrant it; additional charges (e.g., CPT 81015) may apply for the reflex component ([intellitestmanager.questdiagnostics.com](https://intellitestmanager.questdiagnostics.com/home/output/238707?utm_source=openai)).

Limitations

Limitations not explicitly detailed on the site; however reflex depends on initial screen results and insufficient volume or compromised specimen integrity (e.g., bloody or mucoid) may alter reflex logic or result in manual reflex variants ([intellitestmanager.questdiagnostics.com](https://intellitestmanager.questdiagnostics.com/home/output/238707?utm_source=openai)).
