Five drug testing methods
The most widely used drug testing method, urine drug testing detects drug metabolites in a specimen to identify substance use. Backed by certified laboratories and strict chain-of-custody procedures to ensure accuracy and integrity from collection through results.
Analyzes a small sample of hair to identify patterns of drug use over an extended period — providing a longer detection window than urine testing for a more comprehensive view of a candidate's substance use history.
A simple, non-invasive test that collects a saliva sample to detect recent drug use. Easy to administer and difficult to adulterate, making it a reliable option for workplace and post-accident testing scenarios.
A quick screening option that delivers preliminary results at the point of collection within minutes — keeping your hiring process moving without sacrificing accuracy for time-sensitive situations.
Sends specimens to a certified laboratory for analysis, producing the highest level of accuracy and reliability. Ideal for DOT-regulated programs and any situation where legally defensible results are required.
Managing drug testing across multiple locations used to be a logistical challenge. 3rd Degree's network of collection sites and electronic ordering made the entire process seamless from day one.

How It Works
We handle every step of the drug testing process — from electronic order to collection site coordination to lab-verified result delivery — through our trusted network of screening partners including eScreen, i3Screen, Labcorp, Omega Laboratories, and Quest Diagnostics.
Order a drug test through the platform. The candidate receives electronic instructions and a pass to the nearest collection site — within minutes of the order being placed.
The candidate visits any location in our nationwide collection site network. All specimens are collected following strict chain-of-custody procedures to ensure accuracy and integrity.
The specimen is sent to a certified laboratory — including trusted partners such as Labcorp, Quest Diagnostics, and Omega Laboratories — for analysis using the appropriate testing panel.
Lab-verified results are returned and delivered through the platform. Any non-negative results are reviewed before reporting, and DOT-compliant documentation is generated where required.
