Frequently Asked Questions About Panel Drug Testing

How Soon Can I Expect Results?

One of the hallmarks of Fastest Labs South Denver is our commitment to delivering fast, accurate results. Whether you're undergoing a 5, 10, or 12 panel drug test, most results are available immediately or within a short timeframe, providing the timely insights you need. In cases where the initial screening yields a non-negative result, the sample undergoes GC/MS confirmation—a gold-standard testing method used to verify the presence and concentration of specific substances.

To ensure maximum accuracy, all non-negative results are reviewed by a certified Medical Review Officer (MRO). This added layer of review helps eliminate false positives and supports confident, informed decision-making across personal, legal, and employment-related testing scenarios.

What Happens If My Test Result Is Positive?

If a drug test returns a positive or non-negative result, the next step is confirmation through a GC/MS test to rule out any false positives. This highly specific testing method ensures the validity of the results. Once the confirmation is complete, an MRO will carefully review the findings and, when appropriate, contact the donor to verify any legal prescriptions or relevant medical information.

We take privacy seriously. All test results—regardless of panel level—are handled with the highest level of discretion and in compliance with all applicable state and federal regulations.

In addition to providing accurate results, we offer guidance and professional support to help individuals and employers understand what the results mean and determine any next steps. Our goal is to be a trusted resource throughout the entire testing process, from initial collection to final reporting and beyond.
