16 Panel Drug Test Cup with Kratom, EtG & Fentanyl

16 Panel Drug Test Cup with Kratom, EtG and Fentanyl

The 16 panel drug test from Serenity is an all-in-one urine screening cup built for broad drug screening in one device. This configuration includes specialty panels for kratom (KRA/500), EtG alcohol metabolite (EtG/300) and fentanyl (FYL/20).

It also screens for amphetamines, barbiturates, buprenorphine, benzodiazepines, cocaine, MDMA, methamphetamine, methadone, opiates, oxycodone, PCP, TCA and THC.

The integrated cup design keeps specimen collection and screening in one device. A built-in temperature strip provides an additional specimen check. Results can normally be read in about five minutes when the device is used according to the supplied instructions.

This specific configuration is labeled Forensic Use Only. Always review the product label, package insert and intended-use designation before use.

What Does This 16 Panel Drug Test Test For?

This 16 panel urine drug test screens for the following drugs or drug classes at the listed cutoff concentrations.

Cutoff levels are threshold concentrations used by the screening device. A result below a cutoff does not prove that a specimen contains no drug or metabolite. Learn more in our guide to drug test cutoff levels.

16 Panel Drug Test with Kratom

This configuration includes a KRA/500 kratom panel. This makes it different from many standard multi-panel cups that do not include a kratom-related assay.

The exact target and cross-reactivity of a KRA panel depend on the specific assay used in the device. Do not assume that every KRA/500 panel directly detects 7-hydroxymitragynine simply because the cutoff is 500 ng/mL.

For more information about the difference between kratom, mitragynine and 7-hydroxymitragynine, read our guide to kratom and 7-OH drug testing.

16 Panel Drug Test with Fentanyl

Fentanyl is not included in every standard urine drug screen. This 16 panel drug test with fentanyl includes a dedicated FYL panel with a listed cutoff of 20 ng/mL.

Because fentanyl requires its own screening assay, buyers should always review the complete panel list instead of relying only on the number of panels in the product name.

16 Panel Drug Test with EtG

The cup also includes an EtG/300 panel. EtG, or ethyl glucuronide, is a metabolite associated with alcohol exposure.

This panel is separate from the drug panels in the cup and uses its own listed cutoff of 300 ng/mL.

Detection time can vary. It depends on the substance, amount used, frequency of use, specimen, metabolism and the cutoff of the test. A cutoff should not be treated as a guaranteed detection window.

Why Compare the Exact 16 Panel Configuration?

Two products can both be called a 16 panel drug test cup and still screen for different substances.

Before ordering, compare:

• The complete drug and metabolite list
• Cutoff concentrations
• Fentanyl sensitivity
• Whether EtG is included
• Whether kratom is included
• Regulatory and intended-use labeling
• Cup size and collection format
• Specimen validity or temperature features

How to Use the 16 Panel Drug Test Cup

Always follow the instructions supplied with the exact device. Product inserts and labeling take priority over general website instructions.

1. Prepare the Test

Keep the test sealed until you are ready to collect the urine specimen. Make sure the device and specimen are within the temperature range listed in the product instructions.

2. Collect the Urine Sample

Remove the lid and collect the urine directly in the test cup. Collect enough specimen for the test strips to activate correctly.

3. Secure the Lid

Close the lid firmly after collection. Keep the cup upright on a flat surface.

4. Check the Temperature Strip

Review the built-in temperature indicator within the time specified by the product instructions. The temperature strip is a specimen check and is not one of the 16 drug panels.

5. Wait for the Test to Develop

Allow the test strips to develop. Results are generally read at about five minutes. Follow the exact read-time instructions supplied with the device.

6. Read Each Panel

Read the control and test lines for each drug panel. Do not interpret a panel if the control line does not appear.

See our complete drug testing instructions for additional guidance.

How to Read the Results

Negative Result

A control line and test line are visible for the panel. A faint test line should be interpreted according to the instructions supplied with the device.

Preliminary Positive Result

The control line appears, but the test line for that panel does not appear. Rapid urine drug screens provide preliminary or presumptive results. Follow your testing program and applicable requirements for confirmatory testing when needed.

Invalid Result

The control line does not appear. Do not interpret the affected panel. Repeat the test with a new device and follow the supplied instructions.

For general information about rapid urine drug screening and confirmatory testing, see the FDA information on drugs-of-abuse testing.

Forensic Use Only

This configuration is labeled Forensic Use Only. The purchaser and end user should review the exact product label, package insert and intended-use designation before purchase or use.

Do not assume that this product has the same regulatory status as another Serenity Cup or another 16-panel test simply because the products look similar or screen for similar drugs.

Review our Forensic Use Only product policy and intended-use information.

If your testing program requires a different regulatory classification, review the CLIA-waived 16 panel Serenity Cup and confirm that its drug configuration matches your requirements.
