Worker with Glasses


Considering that more than 75% of substance users are employed, it is likely that you are interviewing or employing an individual who could compromise the integrity, safety, and profitability of your business. For the last few decades substance abuse has increased the frequency of workplace accidents and fatalities, absenteeism levels, the costs of health benefits, and the number of workers compensation claims.

Random drug testing is the proven method for avoiding this kind of loss. Accuracy First Diagnostics offers:

• Confidential urine and hair follicle analysis,
• Breathalyzer for alcohol detection,
Consortium membership options for small businesses, and 

• Onsite testing for job fairs and hiring events

Look to Accuracy First Diagnostics for quality drug testing and background checks. For business or personal use you can count on our team to keep your employees, customers, and family safe.


A pre-employment drug test in North Carolina is used to determine if a prospective hire uses illicit substances or abuses prescription medication. It may also be used for employees who are returning to work after an injury or absence, at which time it may be referred to as a pre-placement drug test. It is common for employers to require a job candidate to complete a pre-employment drug test, and a job offer may be contingent upon the applicant’s ability to pass. These drug tests typically screen for the use of the following illegal drugs (but can test for others if needed):

  • Methamphetamines (meth, speed, crank, ecstasy)

  • THC (cannabinoids, marijuana, hash)

  • Cocaine (coke, crack)

  • Opiates (heroin, opium, codeine, morphine)

  • Phencyclidine (PCP, angel dust)
