LabCorp typically uses a cutoff of 50 ng/mL for THC (the psychoactive component of cannabis) in urine drug tests. This means that a result below this threshold is considered negative, while a result at or above this level is considered positive. However, specific cutoff levels may vary based on the type of test or specific program guidelines, so it's always best to consult LabCorp directly for the most accurate information.

If lab testing is testing for THC of thirty instead of fifty will a faint line on an over the counter be considered a positive or negative result in the lab?
In this scenario, a faint line on an over-the-counter test indicates a lower THC concentration, likely below the lab's threshold of thirty. Therefore, it would likely be interpreted as a negative result in the lab test, as it suggests THC levels are below the specified cut-off point for detection.
How much of a drug in your system makes a UA test positive?
Drug tests have standard cut off concentration for detection for each drug and drug test, one reason is to avoid false positive results from second hand smoke, incidental ingestion, etc... for example .. standard THC (major marijuana metabolite) cut off for urine drug test is: most home test kits/ lab initial screen or immunoassay test - 50ng/ml (50 nano grams THC per 1 milliliter urine) and 15ng/ml at the Lab confirmation test usually GC/MS (gas chromatography - mass spectrometry ). Confirmation test is applied to samples that test positive during the initial test .. So concentration of thc above this cut off make test positive for thc.

Is 2 weeks long enough to get THC out of your system?
It all depends on your metabolism and usage. You can buy a self test kit and check it out. I think you can buy them at the pharmacy. Just a small note, if you are going to be tested, know that there are two kinds of urine tests, instant & lab and their cut-offs are not the same. For an instant test, the cut-off is 50ng, but for the lab it is 15ng. So Just because you pass a instant test, doesn't mean you would pass a lab test.
