What testing services do we offer?

Drug Testing 

Drug testing is the process by which organizations use the resources of scientific laboratories to determine if an individual is using illegal drugs. Drug testing commonly requires individuals to submit urine samples for analysis, although occasionally blood or hair samples may be used.

The most popular drug tests are:

  • 5-Panel—The most common testing option is a standard 5-Panel test. This simple test looks for the most common recreational or street drugs, including Phencyclidine (PCP), Marijuana (THC), Cocaine, Opiates (such as codeine and morphine) and Amphetamines (including methamphetamine). 
  • 9-Panel—The 9-Panel test is completed with a urine draw and can help identify Phencyclidine (PCP), Opiates, Marijuana, Cocaine, Amphetamines, Barbiturates, Benzodiazepines, Methadone, Propoxyphene, as well as prescription drugs that are legal to possess and use. Our 9-panel drug test exceeds the industry standard, delivering deeper employee analyses and insights and providing greater peace of mind to critical industries like trucking, day care and education.

Alcohol Testing

Alcohol testing is the process used to determine if individuals are impaired by the use of alcohol. The most commonly used alcohol testing is the Breathalyzer test (also called alcohol breath tests and/or breath alcohol tests). Affordable On-Sites takes pride in offering the most accurate alcohol test to our clients from our highly trained staff.

COVID-19 Antigen Testing

Affordable On-Sites offers CareStart™ COVID-19 Antigen testing at the Durham clinic location or onsite to businesses. The CareStart™ test is a rapid chromatographic immunoassay for the direct detection of the presence or absence of SARS-CoV-2 antigens in the respiratory specimens obtained from clients.

Antigen tests are very specific for the virus, but are not as sensitive as molecular tests. This means that a positive result is highly accurate, but a negative result does not rule out infection.The FDA has granted Emergency Use Authorization (EUA) to CareStart, to allow the test to be used in the United States.

DNA Testing

  • Grand Parentage Testing
  • Maternity Testing
