18 Panel Drug Test with EtG, Fentanyl & Ketamine

18 Panel Drug Test with EtG, Fentanyl & Ketamine

The 18 panel drug test combines urine specimen collection and broad preliminary drug screening in one integrated Serenity 120 mL cup. This configuration includes dedicated panels for EtG, fentanyl, ketamine, tramadol and tricyclic antidepressants together with commonly requested drug and drug-class screening targets.

A defining feature of this product is its dual THC configuration. The cup contains separate THC/50 and THC/200 screening panels, each with its own cutoff concentration. Because THC is represented twice, the device contains 18 screening panels covering 17 distinct drug, drug-class or metabolite targets.

The specialty configuration includes ETG/300, FEN/20, KET/1000, TRA/100 and TCA/1000. These targets are screened separately rather than being assumed to fall under another drug class. Fentanyl, for example, has a dedicated FEN/20 panel in addition to the OPI/300 opiate panel.

The cup also includes individual screening for amphetamines, methamphetamine, benzodiazepines, cocaine, methadone, oxycodone, buprenorphine, MDMA, PCP and barbiturates. This provides broad conventional coverage while retaining the specialty panels that distinguish this configuration from the other 18-panel products.

The Serenity 120 mL format keeps specimen collection and preliminary screening together in one device. A built-in temperature strip provides an additional specimen-temperature reference after collection when checked according to the manufacturer’s instructions.

This product is labeled Forensic Use Only. Buyers requiring xylazine, kratom, gabapentin, K2 or specimen-validity indicators should compare the other available 18 panel drug test cups.

18 Panel Drug Test List and Cutoff Levels

The complete configuration is shown below. Products with the same 18-panel designation can contain significantly different analytes and cutoff concentrations, so the exact panel list should always be reviewed before purchasing.

The two THC assays count as separate screening panels. This is why the product has 18 total panels while covering 17 distinct drug, drug-class or metabolite targets.

FEN/20 is separate from OPI/300, and TRA/100 provides dedicated tramadol screening. KET/1000 is a dedicated ketamine panel and should not be described as an opioid or hydrocodone screen.

Serenity 120 mL Drug Test Cup Features

The Serenity 120 mL cup integrates urine collection and preliminary screening into one device. The specimen is collected directly into the cup, reducing the need to transfer urine into separate rapid-test components during the initial screening process.

All 18 screening panels can be reviewed from the same device after the appropriate development period. The integrated temperature strip provides a specimen-temperature reference shortly after collection when checked according to the product instructions.

This configuration does not list pH, specific gravity or creatinine specimen-validity indicators. Buyers who require integrated ADLTX checks should choose one of the 18-panel configurations that specifically includes those features.

For example, the 18 panel drug screen with EtG, fentanyl, kratom, ketamine and ADLTX provides a different specialty-panel combination together with specimen-validity indicators.

Dual THC Screening – THC/50 & THC/200

This configuration contains two separate THC screening panels: THC/50 and THC/200. Each has its own stated cutoff concentration and produces a separate qualitative screening result.

The two panels should not be interpreted as providing an exact THC concentration, dosage estimate or indication of when marijuana was used. They are preliminary screening assays and should be interpreted according to the manufacturer’s instructions.

The dual THC configuration is also why the device contains 18 total panels despite representing 17 unique screening targets.

EtG, Fentanyl, Ketamine, Tramadol & TCA Screening

The specialty-panel combination is the primary feature that distinguishes this 18 panel drug test from the other products in the category.

ETG/300 provides preliminary screening for ethyl glucuronide, an alcohol metabolite. EtG does not directly measure blood-alcohol concentration or establish current impairment.

FEN/20 provides dedicated preliminary fentanyl screening. The presence of OPI/300 should not be treated as a substitute for a dedicated fentanyl assay.

KET/1000 provides dedicated ketamine screening. Ketamine is a distinct target and should not be described as hydrocodone or another opioid.

TRA/100 provides dedicated tramadol screening separate from the OPI/300 panel.

TCA/1000 provides preliminary screening for tricyclic antidepressants and adds another specialty target that is not included in every 18-panel configuration.

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.

1. Bring the sealed test cup and testing conditions within the temperature range specified by the manufacturer.
2. Collect urine directly into the 120 mL cup to the required specimen level and secure the lid completely.
3. Check the integrated temperature strip within the time period specified by the manufacturer.
4. Activate or expose the screening panels as directed and begin timing immediately.
5. 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 represents 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.

When a definitive analytical result is required, an appropriate confirmatory laboratory method should be used according to the applicable testing procedure and product instructions.

Forensic Use Only

This 18 panel drug test is labeled Forensic Use Only. The product should be selected, used and interpreted according to its current labeling, package insert and intended-use designation.

Forensic Use Only status should not be treated as interchangeable with CLIA-waived status. Another product with the same panel count may carry a different intended-use classification.
