With mixed reviews I didn’t know if these would actually work reliably. So I ended up buying a drug test from the drugstore as well, come to find out tho the results were correct. Test was easy to use and instructions easy to understand.

Follow instructions perfectly, held test in sample till control line appeared, put the cap back on and set on flat surface. 5 minutes later, all tests came back negative. However with 3 different brands on the same sample, 50 mg cut off came out positive. Don’t know how these are allowed to be sold

I would pass on it false negative , both test taken from same sample . All were negative other one was positive .

I tested negative with these, but FAILED my drug test for work!

It tests all the way down to 15 mg/ml. I liked seeing where I was at, and then seeing them all be negative!
