| I had a UA today. I have taken them before and know what a 35105N SAP 5-50 W/NIT is. My question is; on the Quest control form the only thing that was marked was THC,COC,PCP,OPI,AMP. I understand that is a 5 panel test but to what level is this tested to? I have taken 3 First Check home test (who by the way are under some heat from the FDA because of QC issues, found a FDA warning letter posted on the web) and have passed all three (1 about 30 minutes before I went in for the actual test and passed). But those test are at a 50ng/ml level. This was a non-regulated preemployment test. Does Quest do a sneaky-pete and test to a lower EMIT level (<50ng/ml)? I wouldn't think that Quest would go straight to a GC/MS right off the bat, only for a positive confirmation. I understand some test have a threshold of between 38 and 50 ng/ml or could go lower to say 20ng/ml. Does anyone know of a test that would test to a <15ng/ml level? That way I could be sure in the future! I have searched this site and have come up with some good info but not seen anything regarding my questions. |

| "5-50" 5 panel, 50 ng/ml cut-off. I believe you are right with the GC/MS positive confirmation. |

| Vern and Thelma thanks for the replies, SEC and 29Year, Do you have any input on my questions? The 35105N was not marked on the form just the THC,COC,OPI,PCP,AMP and I know it was a UA cause I left pee at the desk, just wondering if anyone knows what kind of cutoff levels are involved with this. Again I was passing with the First Check but am a little leary if the cutoff levels are lower than that... Can a person find a 15ng/ml test strip anywhere for home use? Why does LabCorp test to a lower level? Aren't these test mandated by the FDA to only go to the 50ng/ml level? (Apparently not if LabCorp is at 20ng/ml). Just wondering Thanks, |

| Vern is correct. You are taking a test with a 50ng/ml cutoff limit as requested by the employer. Quest can only do as requested by the employer...no more no less. The only way it will get tested at a lower cutoff to my knowledge is if your initial test came back positive and at that point it will be sent to the lab for confirmation to avoid a false positive. I am not aware of any home tests with a lower cutoff. If you find them out there please let us know. I hope this helps and I was able to answer your question. If you passed a home test I am confidant that you passed the real test. Edit: I just read your post again and I noticed you said that your form didn't say a cuttoff limit. If it didn't tell you then I can't be for sure that it was a 50ng/ml cutoff. Maybe Sec can come and help you out with that. I'm sorry I couldn't help you. I will come back and see what Sec says though so I will know in the future. I hope all goes well for you.

| Why does everyone believe they are getting the most stringent test ever invented. Y'all are going through a standard drug test for pre-employment or random testing. Why would an employer pay huge dollars for a Lowest Detectable Level test on everyone? They wouldn't and they don't. Sure there are tests the have a lower threshhold, but they aren't used for most employment testing. Maybe if you are trying to be a test pilot, astronaut or something like that, they might give you a more detailed test. If you are trying to get an organ transplant, they might give you a more detailed test. But for employment, you all get the standard 50 ng/mL cutoff test for marijuana. Stop being worried about a situation that just doesn't exist for you. For example: I hear they stick a probe up your butt for a colonoscopy. Should I be concerned that something like that will happen during my drug test? Answer: No. Why?: Because that situation just doesn't apply to a standard employment drug tests and neither does a lower screening cutoff level for THC. |
