Ketamine is a dissociative anesthetic developed in 1963 to replace PCP (Phencyclidine). While Ketamine is still used in human anesthesia and veterinary medicine, it is becoming increasingly abused as a street drug. Ketamine is molecularly similar to PCP and thus creates similar effects including numbness, loss of coordination, sense of invulnerability, muscle rigidity, aggressive / violent behavior, slurred or blocked speech, exaggerated sense of strength, and a blank stare. There is depression of respiratory function but not of the central nervous system, and cardiovascular function is maintained. Ketamine's duration of action in a clinical setting is 30 min to 2 h intramuscularly and 4–6 h orally.

 

【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.
