There is no single standard 20 panel. Labs and cup makers each choose their own twenty. Most instant cups share a core of street and prescription drugs and then add 6-MAM or tramadol; some lab 20 panels focus on opioids instead. Our cups include both 6-MAM and tramadol. Check the list your court, program or employer requires before you order.

Both cups are labeled Forensic Use Only.

Each cup has a control line on every strip, so you can see that the test ran. A temperature strip and three adulterant pads check the sample at collection, and the lid keeps it sealed for storage or for shipping a non-negative to a lab. The cup is self-contained, so no other equipment is needed.

Each strip is a lateral flow immunoassay. If the drug is in the urine above the cutoff, it blocks the antibody from binding at the test zone, so no T line appears (preliminary positive). If the drug is absent or below the cutoff, the T line appears (negative). The result is qualitative: it shows above or below the cutoff, not how much was taken. Some medicines can cross-react, which is why lab confirmation by GC-MS or LC-MS/MS gives the definitive result.

These drugs aren't on most 5 to 12 panel cups, but many treatment and supervision programs ask for them. K2 and kratom are not caught by the THC or opiate strips. Gabapentin and tramadol are prescription drugs. 6-MAM separates heroin from other opiates.

A prescription can explain a positive gabapentin, tramadol, oxycodone, buprenorphine, methadone or benzodiazepine result, so record current medicines at collection and have a medical review officer review positives where your program requires it.

Setting	Main uses	Best-fit cup	Why
Probation and parole	Random and compliance testing	90 mL economy cup	Lower cost per test; alcohol, fentanyl and K2 on one screen
Drug courts and family courts	Phase progression, relapse checks, court-ordered tests	Either cup	Send non-negatives to a lab before using them as evidence
Corrections and jails	Intake and post-visit testing	90 mL economy cup	K2 and buprenorphine strips plus adulterant checks
Treatment, MAT and sober living	BUP/MTD adherence, relapse, drinking	120 mL cup	Shows prescribed treatment drugs alongside fentanyl, gabapentin, kratom and EtG
Employers (non-DOT)	Pre-employment, random, post-incident	Either cup	DOT-regulated tests must go to an HHS-certified lab (49 CFR Part 40)

Pick a 20 panel cup when your program has to watch K2, kratom, gabapentin, alcohol, fentanyl and heroin at the same time as the usual street drugs, and wants a tamper check on every sample. One cup replaces a 12 panel cup plus separate EtG, fentanyl, K2 and adulterant tests, so there is one collection, one read and one record. If you don't need those extra drugs, a smaller panel costs less per test.
