clear urine test,...................

Hi,

Been suffering from severe fatigue, dizziness, anyway MS nurse recommended i had a urine sample done, so took one in yesterday, it was clear (dip stick), but GP ha asked for another one to send off to hospital lab, does anyone know why if this one was clear??

Any help would be gratefully received.

Love cxxxx

Just guessing that there are more sensitive tests that maybe rely on something microbial being successfully cultured over a period of time e.g. a couple of days.
