Choosing the right panel depends on your testing purpose. We offer 5, 10, 12, 14, 16, 18, 20, and 22-panel urine drug tests, giving you precise control over which substances are screened. Our staff at the Sioux Falls location can walk you through the differences so you leave with the right test for your situation.

Panel Tiers & What They Cover

The standard DOT-mandated urine screen is a 5-panel test covering marijuana (THC), cocaine, amphetamines, opiates, and PCP. Expanded panels add substances such as barbiturates, benzodiazepines, methadone, ecstasy/MDMA, oxycodone, fentanyl, and others. Courts, probation programs, and employers often have distinct panel requirements, so the right choice depends on who’s requesting the test and why.

Flexible Screening Options

Our FasTest panel drug tests allow for targeted or comprehensive substance screening. Urine testing is accepted across the full range of contexts, including pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and court-ordered screenings. mobile urine drug testing is also available for employers who need on-site collection at their location.

The Urine Drug Testing Process at Our Sioux Falls Lab

Our process is straightforward from start to finish. A trained, certified collector guides each client through sample provision in a secure, private collection area. Tamper-resistant chain-of-custody documentation is completed for every specimen, which supports legally valid results for employment, DOT, or court-ordered purposes.

• Sample collection: A certified collector walks you through providing a specimen in a private, secure area with no ambiguity about the process.
• Chain of custody: Strict tamper-resistant procedures document every step, supporting accurate and legally defensible results.
• On-site analysis: Most screens are analyzed at our Sioux Falls collection site. Negative results are typically available in as little as 15 minutes.
• Lab confirmation: Non-negative results are sent to a GC/MS accredited laboratory for confirmation, with results typically available within 1-3 additional days.

Every urine drug test we conduct follows federal and state guidelines, making results appropriate for South Dakota workplace, DOT, and court-ordered contexts. For DOT-regulated employers, our process complies with 49 CFR Part 40 requirements. It’s worth noting that while South Dakota has medical cannabis laws, federal DOT drug testing requirements remain unchanged and continue to screen for THC. Employers subject to DOT rules must follow federal standards regardless of state law.

Substances Detected by Urine Drug Tests

Detection windows vary by substance, individual metabolism, and frequency of use, ranging from a day or two for some substances to several weeks for others. Our staff explains detection windows for specific substances and helps clients match their panel choice to their compliance or personal needs. At FastestLabs, urine drug tests detect drugs consumed within the past 2-10 days for most common substances.

Depending on the panel selected, urine drug tests can screen for:

• Marijuana (THC)
• Cocaine
• Amphetamines and methamphetamines
• Opiates, including codeine and morphine
• Phencyclidine (PCP)
• Barbiturates
• Benzodiazepines
• Ecstasy/MDMA
• Methadone
• Oxycodone
• Fentanyl and synthetic cannabinoids (available on expanded panels)
