17 - 28 panel drug tests

Choosing an Expanded Multi-Panel Drug Test

An expanded multi-panel drug test brings multiple screening assays into one urine collection device. The important purchasing decision is which assays are included and whether their cutoff levels match your requirements.

Two cups with the same panel count can have different configurations. One may include gabapentin, while another adds xylazine or K2/Spice. Some configurations also use separate screening panels for the same target at different cutoff levels. For this reason, the number of panels does not always equal the number of distinct substances screened.

Before ordering, compare these details:

• Required screening targets: Confirm that every substance you need appears in the product’s complete analyte list.
• Cutoff concentrations: Compare the cutoff for each required assay rather than assuming all configurations use the same levels.
• Specialty coverage: Check for dedicated panels when your requirements include substances beyond the conventional drug list.
• Cup format: Review collection capacity and device features on the selected product page.
• Specimen-validity checks: Confirm whether pH, specific gravity and creatinine indicators are included.
• Intended-use designation: Select the exact device according to its labeling and instructions.

For a focused comparison, browse our 18 panel drug test cups or review the configurations in our 21 panel cup collection.

Specialty Panels and Specimen-Validity Features

Selected configurations in this collection offer dedicated screening for specialty targets. These can include fentanyl, EtG alcohol metabolite, kratom, ketamine, tramadol, gabapentin, xylazine and K2/Spice. Other selected products list additional targets such as LSD, 6-MAM, tianeptine, medetomidine or nitazenes.

These panels are configuration-specific. A higher panel count does not guarantee that a particular specialty assay is included. Check the exact product list and instructions, including any assay limitations, before purchasing.

If you are comparing larger configurations, explore our 24 panel drug test cups and 28 panel drug test cups. Compare their individual screening targets rather than treating one configuration as a direct replacement for another.

Specimen-validity indicators are separate from drug panels. Selected cups include pH, specific gravity and creatinine checks to provide preliminary information about specimen characteristics. These checks do not identify a drug and should be reviewed separately from the drug-screening configuration.

Intended Use and How to Read Results

Review the intended-use designation for the exact cup you select. Products in a shared category do not automatically have the same regulatory status or permitted use.

For a product labeled Forensic Use Only, follow that designation and the supplied instructions. Do not assume the device is suitable for clinical diagnosis or routine workplace testing. Likewise, verify any CLIA-waived designation for the exact configuration rather than applying it to the entire collection.

For collection and interpretation:

1. Check the device’s expiration date and follow the preparation instructions.
2. Collect the urine specimen as directed for the selected cup.
3. Follow the instructions for closing or activating the device.
4. Read each assay within its specified reading window.
5. Interpret drug-screening and specimen-validity results separately.

Follow the product insert for the exact line pattern:

• Negative: The assay meets the manufacturer’s criteria for a negative screening result.
• Non-negative: The assay meets the criteria for a presumptive non-negative result and requires appropriate laboratory confirmation.
• Invalid: The assay does not meet the control requirements; repeat testing according to the instructions.

A negative result does not prove that a substance is absent. Rapid screening results also do not establish impairment, dosage or the exact time of use.

Frequently Asked Questions About 17–28 Panel Drug Tests

What does a 17–28 panel drug test screen for?

The substances screened depend on the exact configuration. Review the product’s complete analyte list and cutoff table to confirm whether it includes every target you require.

Does a higher panel count always mean more distinct substances?

No. Some configurations include more than one assay for the same target at different cutoff levels. Compare the individual screening targets as well as the total panel count.

Do all expanded drug test cups include fentanyl, kratom and gabapentin?

No. Specialty panels vary by configuration. Confirm that the selected product explicitly lists each required assay and its cutoff.

Are adulteration checks included in the drug panel count?

Specimen-validity checks such as pH, specific gravity and creatinine are separate from drug-screening assays. Review both features independently when comparing cups.

Can these cups provide confirmed drug test results?

No. These devices provide preliminary screening results. Non-negative results require confirmation by an appropriate laboratory method before they are treated as confirmed findings.

Bulk Orders for Expanded Drug Test Cups

When ordering multiple cups, select a consistent configuration with the required screening targets and cutoff levels. Matching panel counts alone does not ensure that two products are equivalent.

Compare quantity pricing on the selected product page. For help choosing a configuration or planning a larger order, email info@drugtestingcup.com or call 561-879-7718.

Include your required analytes, preferred cutoffs, intended use and estimated order quantity. This helps us narrow the selection to relevant products and prepare an appropriate quote.
