A member asked:

Wat time of the menstrual cycle is it best to take the 24 hour urine cortisol test? would taking it on the 2nd day of bleeding pose any problems?

Yes: Any 24 hr urine collection should be done when you are not having menstrual bleeding, otherwise the blood in the urine will give incorrect results.
