All First Check products go through rigorous analysis to ensure the highest level of quality. Clinical studies are performed on all of our products, determining their effectiveness, accuracy, and precision. At First Check, we have a strong commitment to bringing you innovation that is in touch with your needs.

What superior R&D has brought to First Check:

  • First to market with drug cup technology
  • First to market with prescription drug testing
  • Substance Abuse and Mental Health Services Administration (SAMHSA) standardized cut-off levels for illicit drugs

First Check is the first to bring the easy to use one-step cup technology to market. This cup technology offers hygienic testing and simple activation to ensure the least amount of human error.

First Check was the first to offer a home drug test that can not only identify the possible use of illicit drugs but can also identify the possible use of five of the most commonly abused prescription drugs.

The cut-off levels for our First Check® Home Drug Tests for illicit drugs are those standardized under the federal government guidelines issued by the National Institute on Drug Abuse (NIDA) and the Substance Abuse and Mental Health Services Administration (SAMHSA).
