DOT / Non-DOT Drug Testing

WDTC works with businesses and organizations of all sizes to manage their drug testing needs. We work with clients combining state-of-the-art methodologies to ensure fast, accurate results. WDTC provides cost-effective drug testing programs for

    • Pre-employment screens
    • Random testing
    • Post-accident
    • Reasonable suspicion
    • Return-to-duty
    • Follow-up drug testing

WDTC offers both onsite and mobile drug testing options, which makes it easier for businesses to have their employees screened. By coming directly to your business, employers don’t lose production time because the donor is traveling to and from the testing facility. You can also choose to send your employees to one of our more than 8,000 collection site partners across the country. A Medical Review Officer looks at all DOT tests to ensure their accuracy.

In addition to traditional urine testing, WDTC also provides:

  • Hair Drug Testing: A person’s hair can show signs of drug use within the past 90 days compared to a typical urine screen that only goes back seven days. It’s also nearly impossible to “beat” a hair drug test. The test also shows chronic drug use is chronic and if the person has taken multiple drugs.
  • Saliva Testing: Saliva testing can show more immediate drug use and saves businesses and workers’ time. An absorbent collection device is placed in the employee’s mouth and quickly gathers the saliva so the worker and tester don’t have to wait until he or she “has to go.” Saliva tests can show more recent drug use than traditional urine tests — as quickly as 30 to 60 minutes after a drug has been ingested.
  • Fingernail Testing: Drugs can be identified in nail clippings two to four weeks following ingestion and can be detected up to eight months after last usage.

Whichever method clients choose, WDTC is committed to streamlining the collection process using both traditional and electronic platforms. Our electronic process is web-based and eliminates the paper chain of custody forms.
