Did my 24 urine on Sunday. The lady at the lab decided to show me the little vial they actually test after my gallon of collection, but I understand they need the concentration from an entire day. Good luck with your results, I'm crossing my fingers on mine because my dipstick protein went from +1 to +4 in one week. The cranberry juice comment does make me think if that was what was causing headaches for me too? I never can tell what causes my headaches but if I start getting them frequently I usually go back to a basic diet and stress relief routine.
