analytical method must be used to obtain a confirmed result. Gas chromatography/mass
spectrometry (GC/MS) is the preferred confirmatory method.

This product is For Forensic Use Only.

Dilute with water

Use the Test strip

Read Result

Two lines indicate a negative result — no fentanyl detected. Even a faint T line confirms negativity in the sample mixture.

Positive result — Only the control line appears. Beware of faint lower lines; if visible after 5 minutes, it's still a negative result. Avoid confusion.

Invalid Result — No lines or only a T line observed. Retest using a new strip, ensuring a full 15-second dip to prevent inaccurate results.
