8 Panel Drug Test Cup with K2 and EtG
This 8 panel drug test combines urine collection and preliminary drug screening in one integrated cup. The configuration includes dedicated panels for K2/Spice and EtG together with THC, cocaine, opiates, methamphetamine, buprenorphine and benzodiazepines.
The test includes K2/50, ETG/300 and OPI/2000. These specifications make it different from other 8-panel cups that may use an OPI/300 cutoff or replace K2 with fentanyl or another analyte.
This specific configuration is labeled Forensic Use Only.
Compare all 8 panel drug test cups before ordering. Drug combinations and cutoff levels vary between products with the same panel count.

What Does This 8 Panel Drug Test Test For?
This 8 panel urine drug test contains the following screening targets and cutoff concentrations.
| Drug or Drug Class | Abbreviation | Cutoff |
| Marijuana Metabolite | THC | 50 ng/mL |
| Cocaine Metabolite | COC | 300 ng/mL |
| Opiates / Morphine | OPI | 2,000 ng/mL |
| Methamphetamine | MET | 1,000 ng/mL |
| Synthetic Cannabinoid / K2 | K2 | 50 ng/mL |
| Ethyl Glucuronide | ETG | 300 ng/mL |
| Buprenorphine | BUP | 10 ng/mL |
| Benzodiazepines | BZO | 300 ng/mL |
A cutoff is the screening threshold for an individual assay. It does not show the exact amount of a substance present, when it was used or whether a person is currently impaired.
For more information about screening thresholds, review our drug test cutoff level guide.
8 Panel Drug Test with K2
A key feature of this 8 panel drug test with K2 is the dedicated K2/50 screening panel.
K2 and Spice are names associated with synthetic cannabinoids. They are different screening targets from the marijuana metabolite detected by a standard THC urine assay.
This cup therefore contains separate:
- K2/50 screening
- THC/50 screening
The two panels should be read independently.
The U.S. Drug Enforcement Administration identifies K2 and Spice as names associated with synthetic cannabinoids designed to produce effects similar to THC. See the DEA information about Spice and K2 synthetic cannabinoids.
K2 Screening Is Not the Same as THC Screening
K2 and THC should not be treated as interchangeable drug-test panels.
A conventional THC assay is designed to screen for a marijuana-related metabolite at its stated cutoff. It should not automatically be assumed to detect synthetic cannabinoids.
This product includes both panels because they target different screening categories.
When comparing 8-panel cups, verify whether the configuration lists:
- THC only
- K2 only
- Both K2 and THC
- Neither panel
8 Panel Drug Test with EtG
The cup includes a dedicated ETG/300 panel.
EtG, or ethyl glucuronide, is a metabolite associated with alcohol exposure. It is screened separately from the drug panels in the cup.
An EtG urine screening result is not the same as a breath alcohol measurement. It does not provide a blood alcohol concentration and does not determine current impairment.
The period during which EtG may be detected is not fixed. Timing can vary based on exposure, metabolism, specimen concentration and the cutoff used by the test.
OPI/2000 Opiate Screening
This configuration uses an OPI/2000 cutoff.
That means its opiate assay uses a listed screening threshold of 2,000 ng/mL.
Do not assume that every 8 panel drug test cup uses the same opiate cutoff. Other products on DrugTestingCup.com may use OPI/300.
For example, the Economy 8 panel K2 and EtG cup uses a different opiate configuration. Always compare the exact cutoff before ordering.
Buprenorphine Screening
The cup includes a dedicated BUP/10 panel.
Buprenorphine should not automatically be treated as part of a broad opiate assay. This product provides BUP as its own screening target.
The BUP and OPI panels should therefore be read separately.
K2 & EtG vs. EtG & Fentanyl 8 Panel Cups
This product uses a panel position for K2/50.
If your program requires fentanyl instead of K2, compare the Economy 8 Panel Drug Test Cup with EtG and Fentanyl.
The two products should not be treated as interchangeable because their screening targets differ.
How to Use the 8 Panel Drug Test Cup
Always follow the package insert supplied with the exact device. Manufacturer instructions and current product labeling take priority over general website information.
Always follow the instructions supplied with the exact product received.
- Inspect the sealed product and check its expiration date.
- Open the pouch immediately before collection.
- Collect the urine specimen directly in the cup to the level stated in the instructions.
- Secure the lid.
- Check the temperature strip within the time and temperature range specified in the instructions supplied with the product.
- Peel back the label to expose the result windows.
- The current product instructions state that results should be read after approximately five minutes.
- Do not interpret the cup after the maximum reading time listed in the instructions.

How to Read the Results
Negative Result
A valid negative panel normally shows both a Control line and a Test line.
A faint Test line should be interpreted according to the instructions supplied with the device. Line darkness should not be used to estimate drug concentration.
Preliminary Non-Negative Result
The Control line appears, but the Test line for that individual panel does not appear.
This is a preliminary screening result. It should not automatically be treated as a definitive laboratory result.
Invalid Result
If the required Control line does not appear, the result is invalid.
Do not report a panel without a valid Control line as positive or negative.
Forensic Use Only
This specific 8 panel drug test with K2 and EtG is categorized as Forensic Use Only.
Do not assume that it has the same intended use or regulatory classification as another 8-panel test simply because the products have the same number of panels.
The product label, package insert and exact intended-use designation control.
Review our Forensic Use Only policy and customer acknowledgement before purchase or use.
