Can drug testing labs detect the difference between male and female urine samples?

Technically a drug testing lab could run a DNA test to determine the gender from which the sample came, but this kind of check is not done in a standard drug test. Procedures used by drug testing labs are tuned to prevent many ways of cheating, and if samples are falsified, the resulting sanctions would generally be the same as if the test returned a positive result.
