How long can a urine sample stay good before being analized?
== == That depends on what you're testing for. Urine drug levels are good at room temp or in the fridge for several days. Microalbumin testing is also good for several days in the fridge. However, if the urine is being collected for a routine urinalysis or a microscopic, the urine needs to be tested as soon as possible. Cellular components, bilirubin, and urobilinogen break down quickly after specimen collection, and bacterial growth causes glucose to decrease and protein and pH to increase. In my laboratory we only accept urines for urinalysis within 2 hours of collection if held at room temp, or within 4 hours if kept refrigerated.
What is a good result for PH testing?
