How long can a urine specimen sit on the counter before it needs to be refrigerated?

Explanation:
Preserving urine sample integrity hinges on limiting how long it sits at room temperature before refrigeration. Bacteria in urine can multiply at ambient temperature, and chemical properties of the specimen (such as glucose, ketones, pH, and other analytes) can change over time. Refrigerating within about 60 minutes slows bacterial growth and helps stabilize the components, leading to more accurate urinalysis and culture results. That’s why the recommended window is one hour. Leaving it out longer increases the risk of altered results, so the best practice is to refrigerate within 60 minutes.
