Looked up the instructions and information about the test online.

It is highly unlikely that my parents will send the results into a lab for further testing, and the instruction book said that bleach and all that diluting shit will not be detected by the test, that i could actually do all of that and still come up negative on the test, considering he never sends it in to a lab.

Think I'm good if the test picks up on 50ng minimum cannaboids in the sample? Thanks again!
