Operation Flow

Step 1: Sampling
1. Open the container. Make a “Kruuua” noise from the throat to clear the saliva from deep throat, then spit saliva (about 2 ml) into the container. Avoid any saliva contamination of the outer surface of the container.
2. Optimal timing of specimen collection:After getting up and before brushing teeth, eating or drinking.
Step 2: Testing
1 Take an extraction tube from the kit and remove a test cassette from the foil pouch by tearing at the notch. Place them on a level surface.
2 Take 200μL fresh saliva samples with a disposable dropper (The absorbed saliva rises to the first scale of disposable dropper) from container.
3 Transfer the saliva samples into the Extraction Tube and shake and mix it.
4 Firmly attach dropper lid to the top of the extraction tube. Then gently invert the extraction tube 5 times.
5 Transfer 3 drops (about 100μL) specimen to the sample well and start counting. Note: If using a frozen sample, the sample must be at room temperature before testing.
Step 3: Reading
15 mins later, read the results visually. (Note: do NOT read the results after 20 mins!)

Result Interpretation


Positive Result
Colored bands appear at both test line (T) and control line (C). It indicates apositive result for the SARS-CoV-2 antigens in the specimen.

Negative Result
Colored band appear at control line (C) only. It indicates that the concentration of the SARS-CoV-2 antigens does not exist or below the detection limit of the test.

Invalid Result
No visible colored band appears at control line after performing the test. The
directions may not have been followed correctly or the test may have deteriorated. It is recommended that the specimen be re-tested.
