Trust Screen Lab provides professional hair drug testing services designed to detect drug use over an extended period. Also known as forensic toxicology testing, hair analysis can identify substance use from approximately five to ninety days prior to collection, offering a significantly longer detection window than urine testing, which typically reflects recent use.

​

Hair drug testing is widely used by employers, courts, and monitoring programs to evaluate patterns of chronic, repeated, or binge substance use. Because of its ability to provide a historical record of drug exposure, it is commonly selected when a more comprehensive assessment is required beyond recent use.

​

Due to its extended look-back period and strong reliability, hair drug testing has become a preferred method for pre-employment screening and ongoing workplace testing programs. It provides organizations with greater confidence when making hiring decisions or maintaining compliance with drug-free workplace policies.

​

When sufficient head hair is not available, body hair may be collected as an alternative specimen in accordance with established procedures. All collections at Trust Screen Lab are conducted by trained professionals using standardized protocols to ensure proper handling and documentation. Specimens are processed by certified laboratories, with results delivered securely to authorized parties to maintain accuracy, confidentiality, and defensible outcomes.
