WARNING: THIS TEST DOES NOT EVALUATE DRUG SAFETY OR PURITY
The Rapid Response™ Fentanyl (FYL) Test Strip is a lateral flow chromatographic immunoassay for the qualitative detection of Fentanyl in human urine at the cut-off concentration of 20 ng/mL and 200 ng/mL for Liquid/powder specimen. It is specific for Fentanyl screening with no significant cross reactivity to other opiates, such as Morphine and Heroin. Interpretation of test results are: positive (one line), negative (two lines), invalid (no lines or no control line).

* A negative result can be interpreted as soon as both the test (T) and control (C) lines appear. A positive result can be interpreted once the control line has appeared and the background has cleared to white, typically by 60 seconds. Do not read results after 10 minutes.
