| Substance | 5-Panel | 10-Panel | Cutoff (ng/mL) |
|---|---|---|---|
| THC (marijuana) | ✓ | ✓ | 50 / 15 |
| Cocaine | ✓ | ✓ | 150 / 100 |
| Opioids (codeine, morphine) | ✓ | ✓ | 2,000 / 2,000 |
| Amphetamines/Meth | ✓ | ✓ | 500 / 250 |
| PCP | ✓ | ✓ | 25 / 25 |

| Methadone | — | ✓ | 300 / 100 |
| Methaqualone | — | ✓ | 300 / 100 |
| Propoxyphene | — | ✓ | 300 / 200 |
The 10-panel costs more (~$50-$80 vs $25-$40 for 5-panel) and is reserved for cases where the additional substances matter.
When each panel is used
5-Panel typical contexts:
- Routine probation drug testing
- Pre-employment workplace testing
- Standard DWI/drug case monitoring
- General misdemeanor case bond conditions
10-Panel typical contexts:
- Prescription drug abuse cases
- Cases involving multiple substances
- Doctor-shopping prosecutions
- Polypharmacy investigations
- Specific federal investigations
- Higher-stakes monitoring (some specialty courts)
THC detection is identical in both
For marijuana cases specifically, the 5-panel and 10-panel use identical THC cutoffs (50 ng/mL screening, 15 ng/mL confirmation). Detection windows are the same:
- Single use: 3-7 days
- Moderate use (2-4x/week): 10-15 days
- Heavy/daily use: 30-60+ days
The panel choice affects whether OTHER substances get detected, not THC accuracy. If your case is purely marijuana-related, the 5-panel and 10-panel produce the same result for your THC test.

Frequently Asked Questions
Which panel will my probation use?
Depends on case type and probation officer discretion. Standard probation cases default to 5-panel. Cases involving prescription drugs, polypharmacy, or high-stakes monitoring use 10-panel. The probation order may specify; otherwise officer chooses.
Can the panel be expanded for cause?
Yes. Probation officers can order additional testing (12-panel, 15-panel, alcohol EtG, fentanyl, etc.) based on circumstances. Cases where defendant's pattern suggests specific substance use beyond panel coverage trigger expanded testing.
Why do panels have different cutoff levels?
Cutoffs are set per SAMHSA standards by substance based on pharmacology and prevalence. THC has lower cutoffs because metabolites are very persistent; opioids have higher cutoffs because therapeutic doses produce detectable amounts.
Is hemp-derived THC tested separately?
No. Both panels test for total THC metabolites without distinguishing source. Hemp-derived products with trace THC can produce positive results identical to marijuana-derived. The hemp-derived defense applies but doesn't prevent the positive test itself.
What about fentanyl?
Fentanyl is not in standard 5-panel or 10-panel. Texas probation programs increasingly add fentanyl as a separate test (often as 12-panel addition) due to the overdose crisis. Defense counsel should confirm whether fentanyl is tested for the specific probation case.
