Specific gravity and creatinine is checked to determine dilution, while pH is checked to determine adulteration.
There are some instant-type test kits available that feature additional panels for SG, creatinine, and pH. With these type of kits now becoming more widely available, the sample not necessarily has to go to the lab to have those checks performed.

In the US, any form of genetic testing cannot be performed on urine samples collected for a drug test unless authorization was granted by the donor. Such authorizations are made on an entirely seperate and detailed consent form.
