Turn-around time

Once your samples arrive at Marvel Laboratories, screening results are typically available to you the same day. Specimens needing additional testing may require 48-72 hours for results.


Test results are reported as Negative or Positive. If your drug level is higher than the established cut-off level, your test will be reported as positive. Many things can affect the length of time a drug or its metabolite can be detected in a specimen, such as:

  • Physical condition
  • Fluid balance and state of hydration
  • Drug metabolism and half-life
  • Route and frequency of use
We encourage all our clients to contract an independent Medical Review Officer (MRO) to review all non-negative test results.
