Hi,

I was wondering if anyone could elaborate on my situation.

I bought a few of the One Step THC test dip strips, and tested my first morning void twice without any fluid beforehand and passed the tests with a faint negative line. I also tested in the day and as the days went on the lines in the day got darker.

My lab test came out positive for thc at the level of 25 ng/ml GC/MS.

I was aware that the 50 ng/ml immunoassay test is equivalent to the 15 ng/ml GC/MS confirmation test.

Can anyone please explain to me why my level wasn't at least close to the 15ng/ml GC/MS level. Is it possible I got a bad batch of test strips ?

Thank You
