I will be taking a Pre-Employment 35105n SAP 5-50 W/NIT test at Quest Diagnostics this coming Monday, and am not sure if I should buy something to help me pass. I stopped smoking four weeks ago, but prior to that I smoked more or less every day for two years, so I guess I was a chronic smoker. I am 5'2'', 115 pounds, never work out, and am unsure about my metabolism. I am fairly thin, but have gained weight the passed six months, since I stopped regularly excercising and continued to eat a lot (diet consists strictly of carbs: pasta, rice, potatoes). I am not sure if four weeks is enough time, and several years ago, I used QCarbo from GNC and passed (although I had quit smoking for over 6 weeks). I don't mind spending the extra money to buy it, as long as I pass, but am reading a lot of posts that recommend not using QCarbo or any other cleansing product. Please let me know what you think I should do, and if you think I have a good chance passing naturally. If not, which products do you suggest? The following is the standard five drug panel, which I got off the Quest site: Drug Group EIA Screen Cutoff Level* (ng/mL**) GC/MS Confirmation Cutoff Level* (ng/mL**) Amphetamines (amphetamine and methamphetamine) 1,000 500 Cocaine metabolite 300 150 Marijuana metabolites 50 15 Opiates (codeine and morphine) 2,000 2,000 Phencyclidine 25 25 * These are standard cutoff levels; alternate cutoff levels may be available. ** Nanograms per milliliter; the above cutoff levels, list of analytes and test methodologies are subject to change when required by applicable government regulations or guidelines. It may be hard to read, so here is the link: Standard Urine Testing for Drug and Alcohol Abuse: Employer Solutions: Quest Diagnostics Thanks!!
