13 – 16 panel drug tests

Compare 13–16 panel drug test cups for expanded urine drug screening, including configurations with fentanyl (FEN/FYL), EtG alcohol metabolite testing, K2/Spice, kratom (KRA), ketamine (KET), tramadol (TRA), gabapentin (GAB) and other specialty analytes.

These multi-panel urine drug tests are available in numerous configurations for professional testing programs, treatment and recovery organizations, correctional facilities, workplace screening and other high-volume testing environments.

Important: panel count alone does not determine which substances a test detects. Two 14-panel or 16-panel drug tests may screen for different analytes or use different cutoff levels. Always compare the complete configuration before ordering.

Compare 13, 14, 15 and 16 Panel Drug Tests

The primary difference between a 13-, 14-, 15- and 16-panel drug test is the number of individual drug or metabolite screening panels included in the device.

However, there is no universal drug list for each panel count.

For example, one expanded panel may prioritize fentanyl and EtG, while another may include specialty panels for K2, kratom, ketamine, tramadol or gabapentin.

The best choice is therefore the test containing the specific analytes your testing protocol requires, not simply the product with the largest number of panels.

13 Panel Drug Test Cups

A 13 panel drug test is a useful step up from traditional 10- and 12-panel configurations when an organization needs one or more additional specialty drug tests.

DrugTestingCup.com carries multiple 13-panel configurations rather than a single fixed 13-panel drug list.

For example, organizations specifically concerned with gabapentin can review the 13 panel drug screen with GAB, EtG and fentanyl. This configuration combines traditional urine drug screening panels with GAB/1000, EtG/300 and FEN/20.

Programs that prioritize alcohol, fentanyl and tramadol can instead compare the 13 Panel Drug Test with EtG, FYL and TRA.

Another option is the 13 panel drug test cup with fentanyl, which provides a different analyte configuration for buyers who specifically want fentanyl screening included in a 13-panel cup.

Because these tests are not identical, buyers should compare all 13 Panel Drug Test Cups before deciding which configuration best matches their testing program.

14 Panel Drug Test Cups

The 14 panel drug test category provides one of the widest selections of analyte combinations in the 13–16 panel range.

One popular expanded configuration is the 14 Panel Drug Test with EtG, fentanyl, K2 and specimen-validity checks. It combines EtG/300, FYL/20 and K2/50 with additional drug panels and pH, specific gravity and creatinine checks.

Organizations wanting a more traditional expanded configuration with EtG and fentanyl can compare the Economy 90ml 14 Panel Drug Test Cup with EtG and FEN.

Programs that specifically require propoxyphene screening should review the 14 Panel Drug Test with PPX and specimen-validity checks.

A different configuration combines specialty screening for PPX, K2 and tramadol in a 14-panel drug test.

These examples demonstrate why buyers should not assume that every 14-panel cup tests for the same substances. See the complete 14 Panel Drug Test Cups category to compare available configurations.

15 Panel Drug Test Cups

A 15 panel drug test cup provides additional flexibility for programs that want traditional drug screening combined with newer or specialty analytes.

For programs where alcohol and fentanyl are priorities, the 15 Panel Drug Test with EtG, FEN, TRA and specimen-validity checks combines EtG/300, FEN/20 and TRA/100 with a broader multi-panel configuration.

Organizations that need synthetic cannabinoid and kratom screening can compare the 15 Panel Drug Test Cup with K2, KRA and TRA. That configuration includes K2/50, KRA/500, TRA/100, FEN/20 and EtG/300 along with its other screening panels.

For programs seeking ketamine and kratom screening, consider the 15 Panel Drug Test with EtG, FEN, KET and KRA, which also incorporates specimen-validity indicators.

Browse all 15 Panel Drug Test Cups to compare the available analytes and cutoff levels.

16 Panel Drug Test Cups

A 16 panel drug test provides broad multi-drug coverage, but there are substantial differences between individual 16-panel configurations.

Organizations looking for fentanyl, EtG, K2 and kratom in one configuration can compare the 16 Panel Drug Test Kit with KRA, FEN, EtG and K2.

Another configuration is the 16 Panel Drug Screen with TRA, EtG and FEN, which includes a different combination of traditional and specialty analytes along with specimen-validity indicators.

If ketamine and synthetic cannabinoids are priorities, review the 16 Panel Drug Test with KET, K2, EtG and FYL.

Programs looking for a combination involving tramadol and broader specialty screening can also compare the 16 Panel Drug Test with TRA, KRA, KET and ADLTX.

View all 16 Panel Drug Test Cups when your protocol requires a specific 16-panel configuration.

Choose a Drug Test by Specialty Analyte

If you already know which specialty substance needs to be included, selecting by analyte may be more useful than starting with panel count.

Common Drug Test Abbreviations

When comparing products, the abbreviation is often more important than the total panel number.

Exact analytes and cutoff concentrations vary by product. Review the individual product specifications before ordering.

Why Cutoff Levels Matter

Finding an analyte on the label is only part of selecting the correct test.

You should also check the screening cutoff level.

Two drug tests may screen for the same drug while using different cutoff concentrations. That is why the complete analyte/cutoff configuration should be reviewed before purchasing.

For additional educational information, see our Drug Test Cutoff Levels guide.

Drug Tests With Specimen-Validity Checks

Many expanded-panel configurations also include specimen-validity indicators commonly listed as ADLTX.

Depending on the product, these may include:

• pH
• Specific Gravity (SG)
• Creatinine (CR)

These are specimen-validity indicators rather than additional drug panels.

Examples include the

• 14 panel EtG/FEN/K2 test with ADLTX, the
• 15 panel EtG/FEN/KET/KRA test

and several of the available 16-panel configurations.

CLIA-Waived vs Forensic-Use Drug Tests

The number of panels does not determine the regulatory classification or intended use of a drug test.

Check the exact product documentation and labeling before purchasing.

Organizations specifically requiring waived tests should browse CLIA-Waived Drug Test Cups.

Programs purchasing devices intended for forensic applications can review Forensic Use Drug Test Cups.

Do not assume that two products with the same number of panels have the same regulatory status.

Who Uses 13–16 Panel Drug Test Cups?

Expanded multi-panel urine testing may be useful for organizations that require broader drug-screening protocols, including:

• Rehabilitation and substance-use treatment programs
• Sober-living organizations
• Correctional facilities
• Probation and parole programs
• Employers and HR departments
• Staffing companies
• Occupational-health providers
• Government organizations
• Institutional testing programs
• Professional drug-screening providers

The appropriate configuration depends on the organization's testing requirements, intended use, applicable regulations and substances that need to be screened.

Bulk 13–16 Panel Drug Test Cups

Organizations performing frequent screening can purchase many of these drug test cups in bulk.

Rather than choosing a product only by unit price, compare:

1. Required analytes
2. Screening cutoff levels
3. Product classification
4. Cup size
5. Specimen-validity features
6. Order quantity
7. Testing frequency

Organizations that need multiple panel counts can browse all Drug Test Cups rather than limiting the search to 13–16 panel products.

For larger orders, visit our Wholesale Drug Testing Supplies resource for information about high-volume purchasing.

Need More Than 16 Panels?

Some testing programs need additional specialty analytes beyond the configurations shown here.

In those situations, compare our 17–28 Panel Drug Tests for higher-panel configurations.

Moving to a larger panel count makes sense only when the additional analytes are relevant to the testing program.

Understanding Rapid Drug Test Results

Multi-panel urine drug test cups provide preliminary screening results.

A negative result generally indicates that the target analyte was not detected at or above the test's screening cutoff under the test conditions.

A preliminary non-negative screening result should be handled according to the instructions, policies and confirmation requirements applicable to the specific testing program.

Frequently Asked Questions About 13–16 Panel Drug Tests

What is a 13–16 panel drug test?

A 13–16 panel drug test is a multi-panel screening device containing between 13 and 16 individual drug or metabolite screening panels. The exact substances included depend on the individual product configuration.

Do all 16 panel drug tests test for the same drugs?

No. There is no universal 16-panel drug list. Different 16-panel products may use their available panels for different substances such as fentanyl, EtG, K2, kratom, ketamine, tramadol or other analytes.

What is the difference between a 13 panel and 16 panel drug test?

A 16-panel test contains more individual screening panels than a 13-panel test. However, a higher panel number does not automatically make a test more appropriate. The correct choice is the configuration containing the substances required by your testing program.

Which panel drug tests include fentanyl?

Fentanyl is available in many 13-, 14-, 15- and 16-panel configurations, but not every expanded-panel test contains a fentanyl panel. Look for FEN or FYL in the individual product specifications.

Which drug test checks for gabapentin?

One available option is the 13 panel drug screen with GAB, EtG and fentanyl, which contains a dedicated GAB/1000 panel.

Which expanded drug tests include ketamine?

Ketamine is available in selected configurations, including the 15 panel KET/KRA configuration and a 16 panel KET/K2 configuration.

Do expanded-panel drug tests include alcohol testing?

Some configurations contain an EtG panel for screening ethyl glucuronide, an alcohol metabolite. EtG is not automatically included in every 13-, 14-, 15- or 16-panel drug test.

What are pH, specific gravity and creatinine on a drug test cup?

They are specimen-validity indicators used to evaluate characteristics of the urine specimen. They are separate from the individual drug or metabolite screening panels.

Are all 13–16 panel drug tests CLIA waived?

No. Regulatory classification and intended use vary by individual product. Always verify the exact product documentation before ordering.

Can I buy 13–16 panel drug test cups in bulk?

Yes. Many of the products in this category are offered with quantity-based pricing for organizations conducting recurring or high-volume testing.
