What Is Panel Drug Testing?
Flexible Screening from 4 to 22 Panels
Panel drug testing refers to the screening of a designated number of drugs in a single test. At Fastest Labs Energy Corridor & Katy, we offer a range of panel tests—commonly 4, 5, 10, 12, and up to 22 panels—so clients can choose the level of testing that best fits their needs. Each “panel” corresponds to a different substance, with higher panel numbers including a broader spectrum of drugs.
Here are examples of substances that may be included in larger panel tests:
- Cocaine
- Marijuana (THC)
- Amphetamines (including methamphetamine)
- Opiates (e.g., morphine, codeine)
- Phencyclidine (PCP)
- Barbiturates
- Benzodiazepines
- Ecstasy/MDMA
- Methadone
- Buprenorphine
- Oxycodone
And more, depending on the panel level selected
Our drug panels are ideal for employers in safety-sensitive industries, legal authorities requiring detailed screening, and individuals seeking personal or pre-employment tests. The broader the panel, the more insight you gain into potential substance use, making it easier to make informed decisions and maintain compliance.

Frequently Asked Questions About Panel Drug Testing at Fastest Labs
What Is the Difference Between Panel Levels?
Each drug panel corresponds to the number of substances tested. A 4-panel test may screen for the most commonly abused drugs, while a 10 or 12-panel test includes additional prescription and illicit substances. Higher panel tests (up to 22) provide the most comprehensive screenings.
Who Should Use Panel Drug Testing?
Panel drug tests are ideal for employers implementing drug-free workplace policies, legal professionals requiring court-admissible testing, and individuals seeking personal insight into substance use. The flexibility of panel levels allows you to select the appropriate test based on your needs and risk level.
How Fast Are Results Provided?
Most rapid panel tests deliver results the same day—often within minutes. If a non-negative result occurs, confirmatory lab testing is used, which may take a few additional days. Our efficient processing ensures timely, reliable outcomes.

Absolutely. We prioritize confidentiality in every part of the process. All sample collections and results are handled discreetly and securely, protecting the privacy of individuals and organizations alike.
