Am I setting myself up for failure? I assume these home kits only test to 50ngs. Does anyone know what Quest tests to (15ngs?) and are there home kits that test to THAT level so I can get a better idea on if I really will piss clean come next week or if I need to be looking at more drastic measures?
Quest Diagnostics uses an assay screen for the initial analysis (usually at a 50 ng/ml cutoff limit). If the sample fails the initial screen, then the sample undergoes the confirmation GC/MS, which has a cutoff threshold of 15 ng/ml.

But dont let the differing cutoff levels worry you. By doing an Advanced Search with the terms "functionally equivalent metabolites", you'll discover that even though their cutoffs numerically differ, a 50 ng assay screen is functionally equivalent to the 15 ng GC/MS.

Search, read, and learn :thumbsup:
