We have talked a lot about how to prepare and pass a drug test, how to make things right and get the results you wish to achieve. But how do you comply with an invalid test result? How would you know that the test worked accurately?

-         Good morning, can you answer a question for me?

-         Of course, would be happy to help you.

-         All right, I was just subjected to a random test and I do not really understand what happened. I used to be a daily Mary Jane smoker, but then I stopped, and a couple months ago I used your permanent detox product for the whole body and haven’t smoked since. I still take my meds every day, but I have prescription for them, and I mentioned it in the paperwork and everything, I just don’t get it – they said invalid test is just as bad as positive.

-         No, that is not true. A positive test rarely has as many second chances, as an invalid test would have. Did they give you any reasons why your sample tested invalid?

-         They said it was something to do with the creatine level, but I’m thinking it must be my meds – I heard that sometimes over-the-counter NSAID could cause an interference with the drug test outcome. Do you know anything about that?

-         Yes, but that will not cause creatine levels to change. Did you drink a lot of water before your test?

-         Sure I did! They pulled me out all of a sudden and I had to urinate right away! I chugged like two bottles down!

-         More than likely that what has altered creatine level, not your medication, and they should know it. Were you told to come back for a re-test?

-         Yes, I think I’m supposed to do it within an hour. So just not drink a lot of water before the test?

-         Exactly. And I’m sure if you inquire with the lab technicians, they will guide you though the procedure and the amount of fluids that will be acceptable to drink before the test.

-         Sweet! Thanks a lot!
