depends what you mean by fresh. If you mean no bug growth then it also depends on the preservatives. No preservatives, less than 24 hours. with boric acid preservative, maybe a weekend.
If you mean the substances tested in the urine. e.g. glucose, bence Jones protein etc, then it depends on what the test is for.
The fresher the sample, the more accurate the result

∙ 14y agoWhen you submit a urine sample at the drug testing laboratory, the temperature of the urine is tested and you cannot bring a sample of urine which has been in the fridge. Once the urine is delivered, it is tested before it is refrigerated. There are changes in urine which can be detected by a microscope to see if it has been in the fridge even if you do manage to warm it to body temperature at delivery to the lab. Reputable labs will test for any kind of alteration in the composition of the urine. It is not advisable to attempt to cheat on a drug test.
