Did you know that DISA provides long-term drug testing methodologies?
Long-term drug testing, such as hair testing, is regarded by many as the best indicator of repeat drug use since it can detect repeat drug use up to a 90-day window. Because hair testing has a wider “detection window,” it eliminates the opportunity for people to abstain for several days prior to being tested to avoid a positive test.
By implementing a long-term methodology like hair, alongside a short-term methodology (e.g., Urine or Oral Fluid), employers have historically identified 2-3 times the number of drug abusers*. This combination of methodologies eliminates testing gaps while ensuring employers make the most informed decisions and build a culture of safety at their workplace.

How is hair testing conducted?
When a donor is selected for a hair test, an indiscriminate sample of hair is collected under direct supervision.
The hair is typically collected from the head but can be sourced from other areas of the body, such as the arms, legs, armpits, etc.
Hair testing is most commonly used for pre-employment and random drug testing policies but can be used in other scenarios as well.
Hair tests can detect all drugs in a traditional 5-panel drug test:
- Marijuana
- Cocaine
- Amphetamines
- PCP
- Opioids
What are the benefits?
- Available with or without Random Testing
- Significantly Higher Positivity Rates When Compared to Historical Averages
- Can Be Combined With Short Term Methodology to Eliminate Drug Testing Gaps
- Wider Detection Window Identifies Lifestyle Usage (from 7 - 90 Days)
- Best Indicator of Repeat Drug Use
- Direct Observed Collection Prevents Tampering
- Resistant to Evasion/Adulteration
- Non-intrusive Sample Collection
