LabCorp, the leading drug testing company in the USA, does not conduct a pat down before a drug test. They offer a 9-panel drug test using urine, saliva, or hair samples. Upon arrival, you will need to check in and show identification. In some locations, LabCorp Express offers an automated check-in system. During the drug testing process, you may be searched, but most tests are unsupervised. For a urine test, you will pee into a cup with a temperature strip, while a mouth swab test involves taking a sample from around the gum line. A hair test will require cutting several strands from against the scalp.
