No its not an issue being from a woman or else I wouldn't have told you to use it. There is a search feature and the substitution sticky you really should use. For instance, the blood test only has a detection window of about 72 hours and has been answered many times before as well as gender of the urine donor.

Nothing out of the ordinary should show up if they run bloodwork and the urine from someone else. The bloodwork might also be for other than drug testing.
