Well, I hope you're right. One other source I was reading.. STERLING Reference Laboratories

"Much of our understanding of detection times is based on research that was done on older, less specific methods and on non-clinical studies. New reagent systems have improved the specificity of commonly employed immunoassays to the THCCOOH metabolite, thus reducing the rate of false positives. This increased specificity has also apparently narrowed the window of detection, particularly for the casual user."

"The metabolite 11-nor-?9-THC-9-carboxylic acid (THCCOOH) is the primary urinary marker of THC use. While immunoassays will react to THCCOOH and other THC metabolites to varying degrees, the confirmation assays are designed to detect only this metabolite."

These are quotes from the article I posted a link to. Maybe i'm not understanding them correctly, but the first one says that Immunoassays are specified to THC-COOH. But the second one does say it will react to other metabolites. Would the "confirmation assays" be the GC/MS? What do they mean by confirmation assays?
Used2Toke Reviewed by Used2Toke on . passed test yesterday, but not today. Thoughts? Hi all, So alittle background on me. I'm 27 yrs old 6' and about 170lbs. I've been a daily smoker for the last 5 years. About 2 weeks ago I was called in for an interview and I knew they would drug test me so I stopped smoking. The interview process took a week and they're just waiting on my background before they send me in to do my drug test (UA at Concentra Urgent Care). I started the Stinger 7 day Detox and finished the regiment last friday. I wanted to check the results so I bought an Rating: 5
