how does the people doing the urine drug test know many loratabs that you are suppose to be taking.a year ago i had a urine test for loratabs i was taking 2 a day and it came back negative. so how can they say a urine test is a hundred percent accurate?

well, who says any test is 100% accurate? i would think that there always has to be some room for error seeing as it's humans setting up and performing the tests.

Thank you for your answer,the dr i had claimed they were.but i knowed i was taking my meds.he claimed i wasnt.
