| AMP | Amphetamines | AMP is the amphetamine strip — it flags Adderall-class prescriptions AND street speed alike. Prescription verified through the MRO reports negative. |
| mAMP | Methamphetamine | mAMP/MET flags crystal meth. Confirmation requires meth ≥250 ng/mL PLUS its amphetamine metabolite, separating meth from pure prescription amps. |
| MET | Methamphetamine | MET is shorthand for methamphetamine on many cup brands — same drug, same confirmation rules as mAMP. |
| MOP | Opiates (morphine/codeine) | MOP is the classic opiate slot at 2,000 ng/mL — morphine, codeine and heroin's 6-MAM marker land here. |
| OPI | Opiates | OPI covers natural opiates (heroin, morphine, codeine). Semi-synthetics like oxycodone usually need their own OXY/BUP strips. |
| COC | Cocaine | COC targets benzoylecgonine at 150/100 ng/mL — crack and powder produce identical metabolites. |
| THC | Marijuana metabolite | THC is the cannabis strip (THC-COOH at 50/15 ng/mL). Fat-soluble storage makes it the longest-lasting common analyte. |
| BZO | Benzodiazepines | BZO flags Xanax/Valium/Klonopin class (~300/200 ng/mL). Not on basic 5-panels. |
| BAR | Barbiturates | BAR is the legacy downer strip (phenobarbital family ~250–300 ng/mL). |
| TCA | Tricyclic antidepressants | TCA screens amitriptyline/imipramine-class ADs — Flexeril(cyclobenzaprine), Benadryl and Seroquel can FALSELY flag it; confirmation resolves. |
| PCP | Phencyclidine | PCP anchors the federal five at a tight 25 ng/mL. DXM, Benadryl and Effexor are famous screen-falsifiers here. |
| BUP | Buprenorphine | BUP catches Suboxone/Subutex at ultra-low ~5 ng/mL — addiction-program staple, newer to employment cups. |
| MTD | Methadone | MTD monitors clinic methadone (~300 ng/mL). Quetiapine and Benadryl can false-flag the screen tier. |
| OXY | Oxycodone | OXY adds Percocet/OxyContin detection (100 ng/mL) that legacy opiate strips miss. |
| MDMA | Ecstasy | MDMA/molly rides the amphetamine-family assay at 500/250 when included. |
| FEN | Fentanyl | FEN is the post-crisis addition at ~1 ng/mL — extremely sensitive, now common on 12+ panel cups. |
| ETG | Ethyl glucuronide (alcohol marker) | EtG proves drinking within ~24–48 h at 100/500 ng/mL cutoffs — abstinence-monitoring standard. |
| K2 | Synthetic cannabinoids | K2 strips chase spice/JWH-family metabolites; coverage updates lag new analogues. |
| PPX | Propoxyphene (Darvon) | PPX is a withdrawn painkiller's legacy strip still printed on some multi-panel cups. |
| EDDP | Methadone metabolite | EDDP confirms actual methadone metabolism (vs. lab contamination) in clinic compliance testing. |
| CRA | Creatinine (validity metric) | Creatinine isn't a drug — labs measure it to catch water-loading dilution (<20 mg/dL = dilute flag). |
