Our trained collectors come to your location to perform professionally documented specimen collection for drug and alcohol testing – with full chain-of-custody integrity from collection to laboratory analysis.
Urine is the most widely used specimen type for workplace drug testing and is the required specimen for all DOT drug tests. Our collectors follow split specimen collection procedures, completing a federal or non-federal Chain-of-Custody Form (CCF) that documents every step from collection to laboratory receipt.
Detection window: Generally 1–7 days for most substances (varies by drug and frequency of use). Hair follicle offers a longer window if extended detection is required.
Oral fluid testing is growing in use as an alternative to urine testing. It detects recent drug use (typically within 24–48 hours), is less invasive, and is highly resistant to adulteration or substitution. Our collectors perform oral fluid collections on-site using certified collection devices.
Note: As of 2024, the DOT has authorized oral fluid testing as an alternative to urine for federal workplace drug testing programs.

Hair follicle testing provides a detection window of up to 90 days, making it ideal for pre-employment screening where longer-term use history is relevant. Our collectors perform hair specimen collection from the scalp (1.5 inches of growth = approximately 90 days of history).
Hair testing is not approved for DOT-mandated testing but is widely used in Non-DOT programs.
