Please Help! Faint Line on First Check Home Drug Test. Will I pass Quest Diagnostic Lab Test? I posted this a couple days before but have not received any feedback! Pleaseeeeeeee Help !!! I have a concern "Can anyone definitively say if the first check home test kit is truly accurate about the presence of faint lines vs. what a true lab test may identify?" My concern is for now 2011 since a lot of post I found are from 2006-2009. Has anything changed or upgraded at the labs to detect THC since ? Are test in labs in 2011 now more accurate or more sensitive than 2008 and 2009? My Lab test was at 3pm. I smoked 7-8 blunts within 17 days before my lab test. But the very last time was 7 days before the lab test yesterday. I drank massive water and cranberry juice 2 days before my Lab Test. On the day of lab test, I flushed starting 3 hours before the Lab Test (at 12pm) with Ultimate Blend 24 (which can be found at most smokeshops). I did the First Check Home kit test at 2:35pm and showed negative with very very faint lines. Since it was faint lines and the box stated that faint lines falls under "negative", I went ahead and Took the Lab Test at Quest Diagnostic at around 3:05pm. I then rushed home to do another Home Kit Test which then appeared completely negative at 3:45pm. So if it was faintly negative half hour before The Lab and then completely negative with solid lines 40 minutes later after the Lab test, is that safe to say that the Lab will detect a "Negative"? I haven't been called yet from the job after 2 days and I am worried sick. I do not want to lose out on the job opportunity. Please help me and let me know. Note: the urine left at Lab had enough color. It was not clear like water, therefore, urine color should not be an issue. Also, since urine did come from me, the urine was at right temperature, therefore, urine temperature should not be an issue either. Thank you Steve for your input. Can you believe that I have called tons of "online" drug test helpline services...and each and everyone of them has advised me that if it was faintly negative half hour before and solid negative half hour after, than that I have absolutely nothing to worry about. Why would these helpline say all this? beats me. I am not a chronic smoker. Actually, I am not even a smoker. What it was that x-mas, and new years came by. Needless to say, then in January, had a bachelorette, 3 birthdays and superbowl party. So I like stupid, fell into the temptation. So even though i am not a smoker per say, by smoking between december and january and last being feb 3rd, this is now my consequences, not expecting at all to be called for the job, let alone, not knowing I would be drug tested, I am now a nervous wreck... I've learned my lesson!
