LabCorp review: False positive

I paid for my own hair, follicle drug test and I wouldn’t pay for something that would give me a result of 48 especially when I hadn’t drank in over a year. I didn’t understand how I got a 48 on a cutoff level of 20 I tried to contact the manager numerous times. I tried to understand how this happened but they changed the blame onto you and then they say that they can charge $200 more dollars to have it retested. I paid for this just prove to a family court Judge that I don’t drink. It was an ETG I ended up going somewhere else where I got a 0.1 i’m not sure what LabCorp did, but they should be refunding people. Worst place ever worst customer service do not trust them.
