5-panel: the SAMHSA basic test
The "NIDA-5" or 5-panel tests for the original federal workplace drug categories:
- Marijuana metabolite (THCA)
- Cocaine metabolite (benzoylecgonine)
- Opiates (codeine, morphine, 6-AM)
- Amphetamines (amphetamine, methamphetamine, MDMA)
- Phencyclidine (PCP)
When used in Texas probation:
- Low-risk misdemeanor supervision
- Pre-trial intervention programs
- Some employer-required tests
- Quick-turnaround supplemental tests when full panels are pending
Cost: $15-30 per test. Turnaround: 1-2 days.
10-panel: standard Texas felony probation
The 10-panel adds five categories to the 5-panel:
- Barbiturates
- Benzodiazepines (e.g., Xanax, Valium, Klonopin)
- Methaqualone (largely historical)
- Methadone
- Propoxyphene (Darvon, phased out post-2010)
When used: most Texas felony probation, state jail felony supervision, drug-related cases regardless of tier. Most defendants in Collin, Dallas, Denton, and Tarrant felony probation receive 10-panel testing.
12-panel: drug court and high-risk supervision
The 12-panel adds two key categories to the 10-panel:
- Oxycodone (separately tested; not detected by basic opiate panel)
- Hydrocodone (separately tested; not detected by basic opiate panel)
Why this matters: hydrocodone and oxycodone are the most commonly diverted prescription opioids. Standard opiate panels miss them because they are semi-synthetic. The 12-panel addresses this gap.
When used: drug court participants, opioid-related cases, federal supervised release, and cases with documented prescription opioid history.
13+ panel and expanded testing
Beyond 12 panels, expanded testing typically includes some or all of the following:
- Buprenorphine (Suboxone, Subutex)
- Fentanyl and analogs (norfentanyl, acetylfentanyl)
- Tramadol
- Carisoprodol / meprobamate (Soma muscle relaxant)
- EtG / EtS (ethyl glucuronide / ethyl sulfate — alcohol metabolites, 80-hour window)
- Synthetic cannabinoids (K2/Spice metabolites — JWH compounds, AB-FUBINACA, AMB-FUBINACA)
- Synthetic cathinones (bath salts — mephedrone, methylenedioxypyrovalerone)
- Kratom (mitragynine — increasingly tested)
- LSD and analogs
- Ketamine
- GHB (gamma-hydroxybutyrate)
13-panel and larger configurations are common in DWI probation (EtG/EtS), federal supervision, CPS reunification cases, and specialty courts (drug court, mental health court, veterans court).
Special configurations and what they signal
Beyond panel count, specific configurations carry meaning:
- EtG-only panel: DWI-specific monitoring; not detecting drugs at all, only alcohol
- THC quantitative monitoring: Required values must decline over time to demonstrate non-use (drug court)
- Hair testing add-on: 90-day retrospective window combined with urine; commonly in CPS and federal cases
- Random call-in: Daily call-in to determine whether testing is required that day (vs. scheduled testing)
- Observed collection: Same panels but with direct observation of the urination — used for high-risk and post-positive cases
- Split-sample collection: Two specimens collected; one tested and one retained for retest

Frequently Asked Questions
How many panels does Texas probation use?
Most commonly 10 panels for felony supervision, 12 panels for opioid-related and drug court cases, and expanded 13+ panels for federal probation, DWI probation (with EtG/EtS), and CPS cases.
Does a 10-panel test for fentanyl?
No. Fentanyl detection requires expanded panel testing (typically 12+ panels) or a specific fentanyl screen added to standard testing.
Does Texas probation test for alcohol on a 10-panel?
No — standard 10-panel does not detect alcohol. EtG/EtS testing must be added separately, or SCRAM continuous monitoring used, to detect alcohol consumption.
Can I find out which panel my probation officer uses?
Yes — ask directly, or have counsel request the testing protocol documentation. The lab name and panel configuration are part of your probation file.
Does a higher panel count mean a stricter probation case?
Generally yes. Expanded panels are reserved for drug court, federal supervision, opioid cases, DWI cases (alcohol metabolites), and CPS cases. Standard 10-panel handles most felony probation.
