Hi

 

Best is to submit fresh urine sample.

If no preservative is added, then urine can be used for labortary test in less than 24 hours after collection in tube.

If boric acid is added as preservative, then it can be tested in less than 48 hours.

But it depends upon what test is requested as proteins get denatured sooner.

 

Please ask more if not clear.
