I am aware that they do look at your creatine levels as well as other things (thanks to the information on these threads) but I did not think I had enough time to ingest creatine monohydrate and wait for my body to process it. I read that they are checking your Creatinine level (which is a byproduct of creatine) and I just figured that it would take some time for it to pass through your system and create that waste.

Thats an interesting bit of information (about the THC test line being faint).

The first home test kit I used actually says very clearly "The presence of ANY line indicates a negative"...

The second one makes no mention of that circumstance. It only states "No line indicates a preliminary" and "A pink/red line indicates a negative".

I know my younger brother had to take one for my parents before and his showed up faint as well. My parents noticed that the test kit they were using said the same "Any line (even faint) indicates a negative".

Has anyone else heard about the THC line coming up faint on a home test kit?
