TEST PROCEDURE(graphic)


Set up for test

Remove one extraction tube and one COVID19 Antigen Test Kit (Lateral Chromatography) cassette from its foil pouch immediately before testing. See Label the test cassette and the extraction tube for each specimen to be tested. Place the labeled extraction tube(s) in a rack in the designated area of the workspace.

Nasal Swab Specimen Collection

To collect a nasal swab sample, carefully insert the swab (supplied in the kit) into the nostril that presents the most secretion under visual inspection. Using gentle rotation, push the swab until resistance is met at the level of the turbinates (about 2.0~2.5cm or near one inch into the nostril). Roll the swab about 5 times against the nasal wall then remove it from the nostril.       


Sample Preparation

Take off the cap of the sample extraction buffer bottle, hold the bottle upside down. Squeeze the bottle to add 7 drops (~210 μ L) of sample extraction buffer into the extraction tube. (See illustration 2) After the specimen collection is done, immediately immerse the swab into the sample extraction buffer. (See illustration 3) In order to make the sample extracting completely permeated into the buffer from swab, rotate the swab against the tube wall repeatedly for 10 seconds and then use fingers to hold the tube (the tube wall is semi-solid) to squeeze the swab for several times while slowly remove the swab out of the tube. (See illustration 4) The purpose of swab squeezing against the tube wall is important, because it can keep the specimen containing liquid to remain in the tube as much as possible. After taking out the swab and discarding it into a biohazard waste container, put on a nozzle (supplied in the kit) to the top of the extraction tube tightly and gently shake the tube to mix the inside liquid well. See illustration 5.

TEST PROCEDURE

1. Read the instruction for use carefully before performing the test.

2. Hold the extraction tube upside down. Squeeze the tube to add 3 drops (about 70- 90 μL) of above prepared specimen liquid through the tube nozzle into the sampling well of the test cassette. See illustration 6.

3. Start the timer. Read the result visually at 15 minutes. Do not interpret the result after 30 minutes.
