What Is a Urine Drug Screen?
A urine drug screen is a laboratory test that checks a urine sample for signs of selected drugs or their breakdown products. The test may screen for several substances through a drug panel. A screening result can show a possible finding, but a qualified review may be needed to interpret unexpected results.

How Urine Drug Screen Works
Urine Drug Screen testing begins when a person provides a urine specimen under a controlled collection process. The sample is labeled and checked so the result connects to the correct person. The test looks for selected drugs or drug breakdown products.

A test panel lists the substances the laboratory will screen. Results may show that a substance was not found, or they may show a finding that needs further review. A Medical Review Officer can assess certain results with medical information. Chain Of Custody records help track the specimen during handling.
For DOT Drug Testing, the screen is part of a structured testing process. The exact panel and review steps depend on the test order and applicable program rules.
