A urine sample is collected and analyzed for the presence of controlled substances, including illegal drugs and prescription medications. 2. Hair Follicle Drug Screen: This type of drug screen involves analyzing a small hair sample near the scalp for an extended detection period, typically up to 90 days. It provides valuable information about a person's drug use history and can detect a wide range of substances. 3. Saliva Drug Screen: The saliva drug screen is a non-invasive method that detects drug use through oral fluid collected using a swab. It offers quick and immediate results, making it suitable for various scenarios such as workplace testing or post-accident investigations. 4. Blood Drug Screen: Blood testing is highly accurate but less commonly used due to its invasive nature and higher cost. It provides an immediate snapshot of drug presence in the bloodstream and is usually conducted in specific situations such as suspected drug intoxication during accidents or criminal investigations. 5.
