Product Reviews of Hair Confirm Hair Follicle Multi-Drug Test Kit, Express, 1 kitProduct Review: Misleading Information!
I was amazed to learn that there are cut off levels with drug tests. I naively thought that you get tested for a drug and if the result is over zero it's positive, if the result is less than zero then it's negative. To my surprise there are cut off levels. How are you to know this if this is your first experience with a drug test? If you spend an additional $69.99 then they will check at a lower cut off level - but it's still not zero! So what good is the test?
