Opiate and Morphine Tests (OPI & MOP)

OPI drug test kits check urine, oral fluid, and cassette samples for opiates like morphine and codeine, and MOP drug test panels can screen for semi-synthetic types too. Treatment centers, clinics, and workplace programs use these opiate drug test kits and morphine drug test formats to get fast, reliable results at the point of care.

Results without the lab wait

CLIA Waived OPI and MOP drug test kits deliver same-visit results for clinics and treatment programs. Send a sample out to a lab instead and you lose the window when an intervention actually helps.

Choose the format that fits

Cups, dips, and oral fluid formats all screen for opiates and MOP, so staff can match the device to how the program collects samples. Pick the wrong format and staff end up fighting the collection process instead of the addiction.

Panels built for today's opioids

Many OPI and MOP panels here pair with fentanyl and 6-MAM detection, catching adulterated opioids a narrow panel would miss. An outdated opiate-only panel can pass a sample that's actually carrying fentanyl.

Documentation that holds up

Forensic Use Only options meet the documentation standard criminal justice and workplace programs require. An OTC result that can't stand up to a chain-of-custody challenge isn't worth much when it matters.

Frequently Asked Questions

What is an OPI drug test and what does it detect?
An OPI drug test screens urine, oral fluid, or a dip cassette for opiates like morphine and codeine, often alongside a MOP marker for semi-synthetic opioids.
What does MOP mean on a drug test panel?
MOP stands for morphine and appears on a drug test panel as the specific opiate marker being detected.
Can an OPI drug test detect fentanyl?
A standard OPI panel does not reliably detect fentanyl, which is why many of these kits pair OPI and MOP with a separate fentanyl panel.
Are OPI and MOP drug test kits CLIA Waived?
Several OPI and MOP drug test kits in this collection are CLIA Waived, allowing point-of-care use without a moderate-complexity lab certification.
What is the cutoff level for a morphine drug test?
Most OPI and MOP drug test cups use a 300 ng/mL cutoff for morphine, matching SAMHSA guidance for opiate screening.

The right OPI and MOP format depends on where you're collecting the sample.

Point-of-care settings like urgent care and telehealth intake usually reach for a cup because it reads fast and needs no extra supplies. Correctional facilities and treatment programs that need documented, defensible results often choose OPI and MOP dip cards instead, since a cassette format is easy to observe and file. Programs testing outside a clinical setting, including at-home and workplace screening, lean on CLIA Waived drug test kits so results carry the same weight without a lab visit. Oral fluid drug tests fit anywhere a urine collection feels intrusive or hard to supervise, and they screen for opiates just as reliably. Matching the device to the setting keeps staff focused on the person being tested instead of fighting the collection process, and it keeps results standing up when someone questions them later.

 

OPI and MOP panels work best when paired with fentanyl and adulteration screening.

Opiates rarely show up alone anymore. Many of the OPI and MOP drug test cups in this collection add fentanyl detection, since illicit opioids are increasingly cut with it and a standalone opiate panel can miss that entirely. Treatment facilities screening for relapse or diversion often add adulteration checks like K2, kratom, or gabapentin alongside OPI and MOP, since these substances get substituted when someone knows what a standard panel is looking for. Forensic Use Only options pair OPI and MOP with the documentation chain-of-custody testing requires, which matters for criminal justice and workplace compliance programs. Building the panel around what a program actually needs to catch, not just the drugs on a standard list, is what keeps testing useful instead of routine.

 

Support is available for building an OPI and MOP testing program from scratch.

Setting up an opiate drug test program for the first time raises real questions about panel selection, cutoff levels, and compliance requirements. The FAQ page covers common OPI and MOP interpretation, storage, and shelf-life questions before you commit to a full order. Treatment facilities weighing a switch from a competitor's panel can find comparison guidance built around the substances local programs are actually seeing, not just a generic drug list. At-home drug test buyers get the same OTC guidance, so a parent or individual testing outside a clinical setting understands a result without needing to call a lab. Whether the program is brand new or being adjusted for the current opioid landscape, the goal is a panel that matches what's actually happening in the field.
