The test youve described is a screen (SAP) of 10 types of drugs with a 50 ng cutoff limit for THC. 2000 ng for a certain off-topic drug that will not be discussed here. NIT is the validity test consisting of the Nitrites check, as well as creatinine, pH, & specific gravity.

If you have an unexpired, unrecalled, untampered batch that has been kept away from direct sunlight, then you have nothing to worry about.
