Drug Testing for Treatment Centers
A drug testing lab built for addiction treatment and behavioral health
Centra Diagnostics provides drug testing for substance use treatment facilities, behavioral health programs and psychiatrists across Los Angeles County. We confirm 81 drugs and metabolites by LC-MS/MS, including fentanyl, xylazine and kratom. Results reach your EMR within 24 hours, and a dedicated account manager supports your staff on site.
Treatment programs make clinical decisions from these results every day. That is why we pair a broad confirmation menu with specimen validity checks, staff training and a local billing team.
A panel that keeps up with the drug supply
Standard screens miss many of the substances now showing up in treatment settings. Centra’s confirmation menu includes:
- Fentanyl and norfentanyl, plus xylazine and its metabolite 4-hydroxy xylazine
- Kratom (mitragynine and 7-hydroxymitragynine)
- Synthetic cannabinoids (JWH-210, JWH-250, UR-144 and XLR-11 metabolites)
- Synthetic stimulants (MDPV, methylone, mephedrone)
- Ketamine and norketamine, gabapentin and pregabalin
- Alcohol biomarkers EtG and EtS
We update our testing devices three times a year to detect newly emerging substances. See the complete list on the testing directory.
Medication adherence and MAT monitoring
Medication-assisted treatment works best when the care team can see whether patients take what is prescribed. Centra confirms both parent drugs and metabolites:
| Medication | What we confirm |
|---|---|
| Buprenorphine | Buprenorphine and norbuprenorphine |
| Methadone | Methadone and EDDP |
| Naltrexone | Naltrexone |
| Antidepressants | Citalopram, fluoxetine, paroxetine, sertraline, hydroxybupropion and metabolites |
| Antipsychotics | Aripiprazole, risperidone, lurasidone, quetiapine, olanzapine and metabolites |
For psychiatric practices, the antidepressant and antipsychotic analytes support medication monitoring alongside substance use testing.
