Why North Charleston Clients Choose FastestLabs
Speed and accuracy aren’t trade-offs here. Every sample is handled by certified professional collectors following strict protocols for confidentiality and precision. Negative results come back in as little as 15 minutes. If a result requires further review, it proceeds to lab confirmation, which generally takes 1 to 3 additional days before final results are issued.
Many national-network services require donors to pre-register online and receive a barcode before visiting a collection site. Our North Charleston facility works differently: walk in without any advance registration, no accounts, no barcodes, and no waiting on a system before you can be seen.
- DOT-compliant testing: Urine is the federally approved method for DOT-mandated testing under 49 CFR Part 40. Our facility meets those requirements for employers with regulated workforces. See our DOT-compliant urine drug testing page for details.
- Panel flexibility: We offer 5, 10, 12, 14, 16, 18, 20, and 22-panel urine drug tests, customizable to your needs. The 22-panel screen is one of the most comprehensive urine screening options available in workplace drug testing.
- Mobile urine drug testing: We can come to your location, reducing employee downtime for workplace testing programs.
- Affordable pricing: Certified testing is accessible to individuals, small businesses, and large organizations alike.
What Our Urine Drug Tests Detect
Urine drug testing can detect drugs ingested within the last 2 to 10 days, depending on the substance and frequency of use. That detection window makes it well-suited for pre-employment screening, random workplace programs, and post-accident investigation. It’s worth noting that urine testing reflects prior substance exposure within that window and doesn’t assess current intoxication. Chronic marijuana users may show detectable THC for significantly longer than the standard window due to how THC accumulates in fatty tissue.
Testing begins with an immunoassay screen. Any presumptive positive proceeds to laboratory confirmation using gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry. Specimen validity testing checks creatinine levels, specific gravity, and pH to confirm each sample’s integrity before analysis, a core component of any chain-of-custody protocol.
We offer 5, 10, 12, 14, 16, 18, 20, and 22-panel urine drug tests. The 5-panel urinalysis is the most basic option. The 22-panel is the most extensive. Detectable substances across our panel range include:

We work with North Charleston employers of every size, from small businesses to government agencies, providing testing that fits their workforce and compliance obligations. A written policy covering screened substances, panel selection, cutoff levels, confidentiality, and consequences is a foundational requirement of any compliant workplace program, and we can help develop one tailored to your organization.
DOT-regulated employers in transportation, trucking, maritime, and other safety-sensitive industries must conduct drug testing under 49 CFR Part 40. We offer DOT-compliant urine drug testing and can help your organization meet those requirements without disrupting operations. Given North Charleston’s proximity to major shipping and logistics infrastructure, many area employers fall under DOT jurisdiction and need a local partner they can count on.
