What finding in a urinalysis suggests that a clean-catch midstream specimen should be repeated?

In a urinalysis, detecting 10 or more organisms/mL indicates a potential contamination issue or the presence of a urinary tract infection. A clean-catch midstream specimen is specifically collected to minimize contamination from the urinary tract's external environment and provide a more accurate analysis of the urine's composition. If the organism count is too high, it suggests that the integrity of the specimen may have been compromised during collection, necessitating a repeat test to ensure accurate results. Repeating the specimen under correct conditions ensures that the test results reflect the actual presence and quantity of bacteria, aiding in accurate diagnosis and treatment.

While a high white blood cell count could suggest infection, it could also be an indication of inflammation, and its implications would require a comprehensive view of other factors. The presence of blood in urine can indicate various conditions but does not necessitate a repeat collection on its own. High pH levels can be influenced by dietary factors or medications but also do not directly indicate a need for a repeat collection in the way bacterial counts do.
