Carfentanyl is an analog of the synthetic opioid analgesic fentanyl. It is 10,000 times more potent than morphine, making it among the most potent commercially used opioids. Carfentanyl was first synthesized in 1974.It is marketed under the trade name Wildnil as a general anaesthetic agent for large animals. Side effects of carfentanyl are similar to those of fentanyl, which include itching, nausea and respiratory depression, which can be life-threatening. Carfentanyl is classified as Schedule II under the Controlled Substances Act in the United States with a DEA ACSCN of 9743.

The Carfentanyl Rapid Test Cassette (Oral Fluid) is a rapid oral fluid screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of Carfentanyl in oral fluid. The Carfentanyl Rapid Test cassette/midstream (Oral Fluid) yields a positive result when Carfentanyl in oral fluid exceeds 50 ng/ml.

 

 

【DIRECTIONS FOR CASSETTE USE】
Allow the test cassette, specimen, and/or controls to reach room temperature (15-30ºC) prior to testing. Instruct the donor to not place anything in the mouth including food, drink, gum or tobacco products for at least 10 minutes prior to collection.
1. Bring the pouch to room temperature before opening it. Remove the test cassette from the sealed pouch and use it within one hour.
2. Remove the collector from the sealed pouch and insert the sponge end of the collector into the mouth. Actively swab the inside of the mouth and tongue to collect oral fluid for a total of 3 minutes until the sponge becomes fully saturated. Gentle pressing the sponge between the tongue and teeth will assist saturation. No hard spots should be felt on the sponge when saturated.
3. Remove the collector from the mouth. Place saturated oral fluid collector into chamber and press sponge fully against the strainer to collect oral fluid. Discard the collector. Snap the cap shut on the collection tube.
4. Place the test cassette on a clean and level surface. Unscrew cap cover from the collection tube. Invert the collection tube and transfer 3 drops of oral fluid (approximately 120 µL) into specimen well of the test cassette and start the timer. Avoid trapping air bubbles in the specimen well. Place screw cap on the collection tube. See illustration below.
5. Wait for the colored line(s) to appear. Read results at 10 minutes. Do not read results after 1 hour.
6. Apply the security seal over screw cap and send to the laboratory for confirmation if necessary.

【DIRECTIONS FOR DEVICE USE】

Allow the test device, specimen, and/or controls to reach room temperature (15-30ºC) prior to testing. Instruct the donor to not place anything in the mouth including food, drink, gum or tobacco products for at least 10 minutes prior to collection.

1. Remove the test device from the sealed pouch and use it within one hour.

2. Insert the absorbent wick to the mouth and put it under the tongue to collect oral fluid until the control line appears.

3. Place the test device on a clean and level surface. See illustration below.

4. Read results at 10 minutes. Do not read results after 15 minutes.
