The Rapid Response™ Fentanyl Test Cassette is a rapid test based on the principle of competitive binding. Therefore, fentanyl that may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody. A drug positive urine specimen will not generate a colored line in the specific test line region of the strip. A drug negative urine specimen will generate a line in the test line region.

Fentanyl is a synthetic opioid related to the phenylpiperidines.1 Fentanyl is approximately 100 times more potent than morphine and 50 times more potent than heroin.2 Fentanyl is commonly used for moderate to severe pain relief.3 As of 2018, fentanyl and its analogs are responsible for the majority of drug poisoning deaths in the United States. Due to the potency of fentanyl, fentanyl poses an extremely high drug poisoning risk especially when used with other drug substances.4 Continued use of fentanyl can lead to opioid use disorder.1
