The test code on the form indicates that the test youre taking is a 10 panel (10 types of drugs, including THC) Immunoassay screen with a 50 ng/ml cutoff limit for THC - which is the same cutoff limit as most home assays.

If all of your home tests consistently show a negative with the first urination of the day (regardless of line intensity), youre good to go. :thumbsup:
So I shouldn't really have to do the dilution method? (Just don't use first urine of the day, and use midstream when I am testing)
(I figure if its getting sent to the lab, they are either doing a GC/MS test or they will test for S/G or Creatine levels)

Also i would like to add, when i am doing my home test , the negative line for other drugs come within less than 10 seconds, while the THC negative line comes 15-20 second after...is that ... normal?

Thanks again!
