Test Preparation for the Longsee Saliva Test Kit

1. Allow all kit components to equilibrate to room temperature (15-30°C) prior to testing for 30 minutes.

Instruction to use the Longsee Covid19 Rapid Test Kit

1. Spit the expectorated saliva into the collection funnel gently as much as possible close to 1mL.
2. Unscrew the collection funnel gently to allow the saliva to flow into the collection tube completely.
3. Screw the nozzle onto the collection tube.
4. Turn upside down the collection tube slightly for 5 seconds, so that the diluent can mix with the saliva sample evenly.
5. Leave the collection tube stand at room temperature for 5 minutes.
6. Remove the nozzle cap.
7. Remove a test cartridge from the sealed pouch by tearing it at the notch and place it on a level surface.
8. Drip 3~4 drops (about 100 μL) of extracted specimens vertically into the specimen well (S) on the test cartridge by squeezing the collection tube.
9. The formation of air bubbles in the specimen well (S) must be avoided. Do not handle or move the test cartridge until the test is complete and ready for reading.
10. Start timer. Read the result within 15 ~20 minutes of adding the sample.
