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 15-panel and 16-panel configurations containing dedicated KET screening panels. Review the individual product analyte list and cutoff level before ordering.

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.
