13 Panel Drug Screen with Gabapentin, EtG & Fentanyl

13 Panel Drug Screen with Gabapentin, EtG & Fentanyl

The 13 panel drug screen combines urine specimen collection and preliminary screening for 13 drugs, drug classes and metabolites in one integrated 120 mL cup.

This configuration is differentiated by dedicated GAB/1000 gabapentin, ETG/300 ethyl glucuronide and FEN/20 fentanyl screening panels.

Along with these specialty targets, the cup screens for amphetamines, buprenorphine, benzodiazepines, cocaine, methamphetamine, methadone, opiates, oxycodone, THC and PCP. Each assay has its own screening cutoff and should be interpreted according to the manufacturer’s instructions.

Gabapentin is one of the main reasons to choose this configuration over a conventional 13-panel cup.

The GAB/1000 panel provides a dedicated gabapentin screening result rather than assuming gabapentin is covered by another drug class.

The FEN/20 fentanyl assay is also separate from the OPI/300 opiate panel. Likewise, ETG/300 provides preliminary screening for ethyl glucuronide, an alcohol metabolite, rather than directly measuring current alcohol concentration or impairment.

This specific configuration is labeled Forensic Use Only.

Buyers requiring another analyte combination, CLIA-waived configuration, ADLTX specimen-validity indicators or a compact 90 mL cup can compare all available 13 panel drug test cups.

13 Panel Drug Screen List and Cutoff Levels

The complete 13 panel urine drug screen configuration is shown below. Panel count alone does not determine which drugs a test screens for, so buyers should compare the exact analytes and cutoff concentrations before ordering.

The stated cutoff is the screening decision threshold for each qualitative assay. This rapid cup does not report the exact concentration of a drug or metabolite in the urine specimen.

Gabapentin, EtG & Fentanyl Screening

The specialty-panel combination distinguishes this product from other 13-panel configurations.

GAB/1000 provides a dedicated preliminary screening assay for gabapentin. GAB should not be confused with GHB; they are different substances and different screening targets.

FEN/20 provides a dedicated fentanyl screening result separately from the OPI/300 assay. The presence of an opiate panel does not mean that fentanyl screening is automatically included.

ETG/300 provides preliminary screening for ethyl glucuronide, an alcohol metabolite. An EtG result should not be described as a direct measure of current blood-alcohol concentration, intoxication or impairment.

This combination is useful for forensic testing programs that specifically require gabapentin, fentanyl and EtG screening in addition to conventional multi-panel urine testing.

120 mL Drug Screen Cup Features

The 120 mL cup combines urine collection and multi-panel screening in one integrated device. The specimen is collected directly into the cup so the initial screening can be performed without transferring urine into separate rapid-test components.

A built-in temperature strip provides an additional specimen-temperature reference after collection when checked according to the manufacturer’s instructions. The result panels are integrated into the cup and are interpreted within the reading window specified in the applicable package insert.

This configuration does not list integrated pH, specific gravity or creatinine ADLTX indicators. Buyers who require specimen-validity pads should select a 13-panel configuration that specifically includes those features.

How to Use and Read Results

Always follow the package insert supplied with the exact product lot because specimen requirements, activation steps and interpretation times are determined by the manufacturer.

1. Confirm the product configuration, expiration date and sealed package condition before testing.
2. Collect the urine specimen directly into the cup to the specimen level specified in the product instructions.
3. Secure the lid and complete any device-specific activation steps described by the manufacturer.
4. Check the integrated temperature strip within the specified period after collection.
5. Begin timing as directed and read all 13 screening panels within the manufacturer’s stated interpretation window.
6. Document the results and follow the applicable procedure for invalid or preliminary non-negative screens.

• Negative: the required 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 and is not the same as a definitive laboratory result.
• Invalid: the required control line does not appear. Do not interpret the affected panel; repeat testing according to the product instructions.

Screening results should not be used to determine dose, impairment or the exact time of exposure. When definitive analytical identification is required, use an appropriate confirmatory laboratory method according to the applicable testing procedure.

Benefits and Appropriate Use

This 13 panel drug screen with gabapentin combines three specialty screening targets with ten additional drug and drug-class assays in a single collection device. This reduces the need to perform multiple separate rapid screens when the required protocol includes GAB, EtG and fentanyl.

The product is intended to provide preliminary qualitative screening results. A non-negative screening result should be handled according to the applicable testing protocol, including confirmatory laboratory analysis where required.

Because this device is labeled Forensic Use Only, its use should remain consistent with the current product labeling and the requirements of the applicable forensic testing program rather than being represented as a general-purpose CLIA-waived clinical test.

Storage, Limitations & Intended Use

Store and handle the test according to the temperature range and environmental conditions specified in the package insert supplied with the current product lot. Do not use a test beyond its labeled expiration date or if the sealed packaging has been compromised.

This cup provides preliminary qualitative screening results. The screening cutoff does not represent the exact concentration of a substance in the specimen, and detection time can vary based on multiple biological and testing factors.

For that reason, fixed universal detection-window claims should not be used to interpret an individual result.

This configuration is labeled Forensic Use Only and should be used according to its current labeling and applicable testing procedures.

Frequently Asked Questions

What does this 13 panel drug screen test for?

This configuration includes AMP/1000, BUP/10, BZO/300, COC/300, MET/1000, MTD/300, OPI/300, OXY/100, THC/50, PCP/25, GAB/1000, ETG/300 and FEN/20.

Does this 13 panel drug screen include gabapentin?

Yes. It contains a dedicated GAB/1000 gabapentin screening panel.

Is GAB the same as GHB?

No. GAB in this configuration refers to gabapentin. GHB is a different substance and should not be used interchangeably with GAB.

Does this test include fentanyl?

Yes. It includes a dedicated FEN/20 fentanyl screening panel separately from the OPI/300 opiate assay.

Does this 13 panel drug screen include EtG?

Yes. ETG/300 provides preliminary screening for ethyl glucuronide, an alcohol metabolite.

Does an EtG result show current alcohol impairment?

No. EtG screening detects an alcohol metabolite and does not directly determine current blood-alcohol concentration or impairment.

Does this cup include ADLTX specimen-validity indicators?

No. This specific configuration does not list integrated pH, specific gravity or creatinine indicators.

Is this 13 panel drug screen CLIA waived?

No. This specific configuration is labeled Forensic Use Only.

Are preliminary positive results final?

No. A non-negative rapid screening result is preliminary and should be handled according to the applicable testing protocol, including confirmatory laboratory testing where required.

Can this 13 panel drug screen be purchased in bulk?

Yes. Quantity-based pricing is available, qualifying orders of 100 cups or more receive free shipping, and larger recurring or distributor orders may qualify for additional wholesale pricing.
