The 18 panel drug screen cup combines urine specimen collection, 18 preliminary drug-screening assays and three specimen-validity indicators in one integrated 120 mL device. This configuration provides broad conventional drug screening while adding specialty panels for gabapentin, EtG, fentanyl, kratom, ketamine and tramadol.
Unlike some products marketed with the same overall panel count, this configuration contains a full set of 18 drug and metabolite targets plus separate pH, specific gravity and creatinine indicators. The ADLTX checks are not counted as drug panels and should be interpreted separately from the screening result lines.
The specialty configuration includes GAB/1000, ETG/300, FEN/20, KRA/500, KET/1000 and TRA/100. These targets are represented by dedicated assays rather than being assumed to fall under conventional drug classes. Fentanyl and tramadol, for example, are screened separately from the OPI/300 panel.
The cup also covers commonly requested drug classes including AMP, BAR, BUP, BZO, COC, MDMA, MET, MTD, OPI, OXY, PCP and THC. The combination makes this product substantially different from the other 18-panel configurations that emphasize xylazine, K2 or different cutoff combinations.
This product is supplied as a Forensic Use Only configuration. Buyers requiring another specialty-panel combination can compare all available 18 panel drug test cups.
18 Panel Drug Screen List and Cutoff Levels
The complete configuration is shown below. Buyers should compare both the analytes and cutoff concentrations because different 18-panel products can have substantially different screening profiles.
| Drug / Target | Abbreviation | Cutoff Level |
|---|---|---|
| Amphetamines | AMP | 1000 ng/mL |
| Barbiturates | BAR | 300 ng/mL |
| Buprenorphine | BUP | 10 ng/mL |
| Benzodiazepines | BZO | 300 ng/mL |
| Cocaine | COC | 300 ng/mL |
| MDMA / Ecstasy | MDMA | 500 ng/mL |
| Methamphetamine | MET | 1000 ng/mL |
| Methadone | MTD | 300 ng/mL |
| Opiates | OPI | 300 ng/mL |
| Oxycodone | OXY | 100 ng/mL |
| Phencyclidine | PCP | 25 ng/mL |
| THC / Marijuana | THC | 50 ng/mL |
| Gabapentin | GAB | 1000 ng/mL |
| Tramadol | TRA | 100 ng/mL |
| Ketamine | KET | 1000 ng/mL |
| Kratom | KRA | 500 ng/mL |
| Fentanyl | FEN | 20 ng/mL |
| Ethyl Glucuronide | ETG | 300 ng/mL |
Additional specimen-validity indicators: pH, specific gravity (SG) and creatinine (CR).
The dedicated FEN/20 and TRA/100 panels are separate from OPI/300. Likewise, KET/1000 is a dedicated ketamine assay, GAB/1000 is for gabapentin screening and KRA/500 provides kratom-related screening.
120 mL 18 Panel Drug Screen Cup Features
The integrated 120 mL cup combines specimen collection and multi-panel screening in one device. Urine is collected directly into the cup, reducing the need to transfer the specimen into separate rapid screening components during the initial testing process.
All 18 screening assays are incorporated into the device, along with three additional specimen-validity indicators. A built-in temperature strip provides another specimen reference shortly after collection when checked according to the manufacturer’s instructions.
The configuration is particularly useful when broad traditional drug screening needs to be combined with specialty targets such as gabapentin, fentanyl, EtG, kratom, ketamine and tramadol.
Buyers who do not require gabapentin can compare the related 18 panel drug screen with EtG, fentanyl, kratom, ketamine and ADLTX. For all available configurations, review the 18 panel drug test cup category.
Gabapentin, EtG, Fentanyl, Kratom & Ketamine Screening
The specialty-panel combination is the main feature that distinguishes this product from the other 18-panel configurations.
GAB/1000 provides dedicated gabapentin screening. The existing older product copy incorrectly identifies GAB as GHB; these are not the same target, so the updated product page should consistently identify this panel as gabapentin.
FEN/20 provides dedicated preliminary fentanyl screening separate from the OPI/300 panel, while TRA/100 provides dedicated tramadol screening.
ETG/300 screens for ethyl glucuronide, an alcohol metabolite. EtG screening should not be represented as directly measuring current blood-alcohol concentration or impairment.
KRA/500 provides kratom-related screening. KRA should not be described as synthetic marijuana or K2. Buyers looking specifically for information about 7-hydroxymitragynine can review our 7-OH kratom testing guide. A standalone kratom urine test cartridge is also available.
KET/1000 provides dedicated ketamine screening and is separate from opioid screening.
Specimen Validity Checks – pH, Specific Gravity & Creatinine
This 18 panel drug screen cup includes three additional specimen-validity indicators: pH, specific gravity and creatinine. These indicators provide information about characteristics of the urine specimen and are not part of the 18 drug-panel count.
- pH: provides information about the acidity or alkalinity of the specimen and can help identify values outside the reference range supplied with the test.
- Specific Gravity (SG): provides information about urine concentration and may help identify unusually dilute or concentrated specimens.
- Creatinine (CR): provides another measure related to specimen concentration and may assist when evaluating possible dilution.
An unusual ADLTX result does not by itself establish intentional specimen adulteration. The pH, SG and creatinine indicators should be interpreted according to the manufacturer’s reference chart and instructions.

How to Use and Read Results
Always follow the package insert supplied with the exact product lot because collection requirements, activation procedures and result-reading times can vary between devices.
- Bring the sealed cup and testing conditions within the temperature range specified by the manufacturer.
- Collect the urine specimen directly into the cup to the required level and secure the lid completely.
- Check the integrated temperature strip and review the pH, specific gravity and creatinine indicators according to the product instructions.
- Activate or expose the drug-screening panels as directed and begin timing immediately.
- Read all screening panels within the manufacturer’s stated interpretation window and do not interpret results after the specified time limit.
- Negative: both the control line and test line appear for the applicable panel. A faint test line should be interpreted according to the manufacturer’s instructions.
- Preliminary Positive / Non-Negative: the control line appears but the corresponding test line is absent. This is a preliminary screening result rather than definitive laboratory confirmation.
- Invalid: the required control line does not appear. Do not interpret the affected panel; repeat testing according to the product instructions.
The specimen-validity indicators use their own reference chart and should not be interpreted using the drug-panel result-line rules. When a definitive analytical result is required, an appropriate confirmatory laboratory method should be used according to the applicable testing procedure.

How to Read the Screening Results
Interpret each drug assay individually within the manufacturer’s specified reading window.
- Negative: Both the control line and test line appear. A faint visible test line is interpreted according to the supplied instructions.
- Non-negative / presumptive positive: The control line appears, but the test line is absent.
- Invalid: The control line is absent, regardless of whether a test line appears.
An assay without a control line cannot provide a valid screening result. Follow the manufacturer’s instructions for repeating an invalid test.
Read the ADLTX indicators separately using the supplied color chart. For a general explanation of line-based results, see how to read a drug test cup.
