Burnt toast. I have a separate question hoping to benefit from your expertise.

I submitted a 10p Labcorp urine drug screen after 1 week of abstinence (prior use a 5-6 hits a week of strong gangja). The morning of the test I tested negative with a light line on an "at-home" drug test. This was the 2nd void after one glass of water and 1 cup of coffee. I thought I was in the clear. I had taken some creatine and multivitamins over the past few days. 1-2 hours before the test I drank 64 oz of Gatorade. My urine was only slightly yellow tinged, almost waterlike when I submitted my sample.

2 days later my boss was notified that my test results were "abnormal" and would require further testing…

I am unsure if this means they think it is dilute and need to test it further or if they are going to run gc/ms which may find THC metabolites above 15ng… (very bad).

Have you ever heard of Labcorp running gc/ms on a dilute sample rather than making the donor retest?

Thanks, definitely freaking out
