They don't test for male or female...You can loosen or remove the cap and nuke it for 5 to 10 seconds and You will be good for hours. Check out this thread for some info, I told all I know in it.....

jeffman Reviewed by jeffman on . QF question plz :) I was wondering about QF 4.0, the bottle I just got says that it is unisex...now, I know there is obviously a difference between male and female urine, so how could unisex work for both without anyone knowing? Sorry, Im just a little paranoid...Also, the hand warmer that comes with the bottle says that it will heat it up to 98-100 degress within an hour, and will last for six hours...is this temperature accurate enough to count on? If so, I plan on rubber-banding the warmer to the bottle, Rating: 5
