10 Panel Drug Test
Same-day scheduling at 17,000 + locations l Confidential results
A 10 panel drug test is considered one of the most comprehensive drug screening options available today. It is specifically designed to detect a range of both common and less frequently abused substances, providing a more thorough assessment of an individual's drug use. This level of detail distinguishes it from the more limited 5 panel drug test, which only identifies marijuana, cocaine, opiates, amphetamines, and PCP.
The 10 panel test expands its scope by including benzodiazepines, barbiturates, methadone, propoxyphene, and Quaaludes (methaqualone). Such an expanded range is critical for identifying drug use that might otherwise go unnoticed in tests with narrower scopes. Because of this comprehensive coverage, the 10 panel test is highly regarded and widely used in various scenarios.
Employers often choose the 10 panel test when screening potential hires or conducting regular checks on current employees, especially in safety-sensitive industries. Its broad scope helps ensure that individuals responsible for critical tasks operate without impairment. As a result, it is often implemented as part of company policies to maintain a safe work environment.
In legal cases, particularly within the state of Castro Valley, CA, the 10 panel drug test is frequently utilized to provide a clearer picture of an individual's substance use. Courts may order this test in situations where understanding the breadth of drug use could influence legal decisions. Thus, it is a preferred option for attorneys and judges needing comprehensive evidence.
Individuals may also opt for a 10 panel drug test to evaluate their own drug use or that of a loved one. It can offer peace of mind, confirm suspicions, or support addiction recovery efforts. Given its accuracy and thoroughness, this drug test is a highly trusted option for anyone needing a detailed analysis of substance use.

10 Panel Lab Based Test vs. 10 Panel Instant Test
Understand the differences - speed vs. defensibility - so you can choose the right 10 panel drug test option for employment, court, and personal testing.
Both options screen the same 10 drug classes (THC, cocaine, opiates, amphetamines/methamphetamine, PCP, benzodiazepines, barbiturates, methadone, propoxyphene, and Quaaludes*). The difference is how results are produced, verified, and used.
*Methaqualone only available in urine lab-based testing
10 Panel Lab based vs. 10 Panel Instant Drug Test
| Feature | 10 Panel Lab-Based | 10 Panel Instant (POCT) |
|---|---|---|
| Primary Use | Employment, legal/court, policy-driven programs | Rapid on-site screening; same-day hiring decisions |
| Specimen | Urine (standard); hair/oral fluid/nail options | Urine (most common) |
| Speed | Negatives 1 business day after lab receipt; non-negatives 2-3 days with MRO | Screen results in 5-10 minutes (presumptive) |
| Accuracy & Confirmation | High; confirmatory GC/MS or LC-MS/MS on any non-negative | Screening only; non-negatives should be lab-confirmed |
| MRO Review | Yes (on non-negative lab results) | Not by default; added when sending to lab |
| Chain of Custody (CCF) | End-to-end documented | Used for screen; lab CCF applies if sent for confirmation |
| Legal Defensibility | Strong (SAMHSA-certified lab + confirmation + MRO) | Limited until confirmed by a lab |
| Compliance | Meets most employer/court policies; DOT uses lab-based 5-panel | Great for rapid screens; policies often require confirmation for final action |
| Cost Profile | Higher unit price; includes confirmation/MRO when needed | Lower upfront; confirmation adds cost/time on non-negatives |
Choose 10 panel Lab-Based If You Need:
- Defensible results for employment, licensing, or court
- MRO oversight to evaluate prescriptions and verify results
- Audit-ready documentation with full Chain of Custody
- Mass-spectrometry confirmation for any non-negative screen
Best for: pre-employment, randoms, return-to-duty/follow-up, post-accident (when policy requires confirmation), legal/custody cases.
Order 10 Panel Lab-BasedChoose Instant (POCT) If You Need:
- Immediate screening at the point of collection
- Faster hiring decisions with on-site programs
- To screen first, confirm only if needed
- Temporary removal from duty pending confirmation (policy-dependent)
Reminder: Instant results are presumptive. Confirm non-negatives at a SAMHSA-certified lab for final decisions.
Order 10 Panel Instant10 Panel Drug Test Detection Times
Windows are driven by drug metabolism and specimen type, not whether testing is lab-based or instant. Urine is standard for both; alternative specimens are typically lab-based.
| Specimen | Typical Detection Window | Best Use |
|---|---|---|
| Urine | 1-7 days (THC up to 30) | Employment, legal, personal |
| Hair | Up to 90 days | History/patterns of use |
| Oral Fluid (Saliva) | 24-72 hours | Recent use; post-accident/suspicion |
| Blood | Hours to 2-3 days | Very recent use |
| Nails | 3-6 months | Extended look-back |
Compliance Notes
- DOT programs require a lab-based 5-panel under 49 CFR Part 40 (not a 10 panel).
- Many employer/court policies require lab confirmation + MRO review for final actions.
- On-site instant testing may require appropriate CLIA credentials depending on device and state rules.
