Thank you so much for the reply. I worked out a bit -ran 2 miles on the treadmill a few days a week. I eat a high fruit & veggie diet but didnt drink any cranberry juice due to mixed reviews about it working -have family high up in the military who told me cranberry juice/water = flushing with liquids is the best bet. I dont have much confidence in my own urine and can't risk it. Do you know anything about my other two inquires as to home test accuracy and microwaving the QF a few hours before my test (start work at 8am, test is at 10.30 am). Again - many thanks for the reply !
