What to Expect From the Testing Process

Urine testing at Fastest Labs of Lewisville produces instant on-site results for negative screens. When a sample returns a non-negative result, we send it to a laboratory for GC/MS confirmation, which uses gas chromatography and mass spectrometry to identify the substance and its concentration. A medical review officer is available to evaluate confirmed results, supporting documentation for employment or legal purposes.

Most non-negative confirmations resolve within one to three business days. Throughout, results go only to the authorized party or organization identified at intake, in keeping with applicable privacy guidelines.

Our certified collectors follow strict identification and chain-of-custody procedures at every collection. Chain of custody is the documented record of who handled a sample and when. It’s part of what supports a result in court or HR proceedings. Pricing is competitive and transparent, with no hidden fees.

Choosing the Right Urine Drug Test Panel

The most common format is the 5-panel urinalysis, which is the standard panel required for Department of Transportation (DOT) drug testing. It screens for marijuana, cocaine, amphetamines, opioids, and phencyclidine. For non-DOT testing, we offer custom panels for employers or individuals who need to screen for additional substances beyond the standard five.

Urine testing is well-suited for routine workplace screenings because it’s cost-effective and reliable across a broad detection window. If you need to identify a history of chronic use over a longer period, hair testing offers an extended detection window and may be the better fit. Our team can help you decide which specimen type fits your situation.

What Happens During Your Visit

From check-in to collection, most visits take under 15 minutes. A certified collector verifies your identification, walks you through the process, and completes the collection under chain-of-custody procedures. Negative results may be available before you leave. If a non-negative result requires lab review, confirmation typically takes a few days, and results are released only to the party or organization you designated at intake, whether that’s you, your employer, or a third-party administrator.

How to Prepare for Your Urine Drug Test

A little preparation helps the collection go smoothly. Stay hydrated before your visit, but avoid drinking excessive fluids right beforehand, since over-hydration can affect sample validity. If you take any prescription or over-the-counter medications, let the testing technician know at check-in. Certain medications and supplements can interact with screening results, and disclosing them upfront allows the medical review officer to account for them if needed. Follow any pre-test instructions provided when you book or inquire, and if you have questions, call us before your visit.

Common Reasons Urine Drug Testing Gets Ordered

Employers order urine drug tests across several standard scenarios:

Pre-employment screening: Confirming a candidate is drug-free before a job offer is finalized
Random testing: Unannounced testing of current employees as part of a workplace drug-free policy
Reasonable suspicion testing: Testing triggered when a supervisor observes behavior consistent with impairment
Post-accident testing: Collecting a sample after a workplace incident to determine whether substances were a factor
Return-to-duty testing: Confirming a negative result before an employee resumes safety-sensitive work

Courts and government agencies may also require urine drug testing as part of compliance programs or legal proceedings. Schools and athletic programs sometimes use urine screening under zero-tolerance policies. Whatever the reason, Fastest Labs of Lewisville accommodates both walk-in and scheduled collections for all of these situations.
