Detailed information

Product detailed description

Before testing, leave the test cartridge, sample and antigen extraction buffer at room temperature (15-30°C).

Remove the test cartridge from the sealed foil bag and use it as soon as possible. Best results are achieved if the test is performed within one hour.

Place the test equipment on a clean and flat surface.

Test procedure

A - Nasal swab

Remove any secretions from the anterior nasal surface and slightly tilt your head. Gently and slowly insert the sampling brush into the anterior nasal cavity (nostril) and rotate several times to ensure proper collection of epithelial cells from the mucus. Wait a few seconds for absorption of secretions, and then gently rotate the brush to withdraw.

B - Throat swab

When swabbing the throat, fully insert the sterile sampling brush provided in the kit into the posterior pharyngeal wall, tonsils and other inflamed areas. Ensure that the brush does not touch the tongue, cheeks and teeth.

Place the antigen extraction tube on the work table. Hold the vial containing the antigen extraction buffer vertically, squeeze the vial so that the buffer drips freely into the extraction tube without touching the edge of the tube, and add 6 drops (about 200 µl) to the extraction tube.

Place the swab sample in the extraction tube containing the pre-added antigen extraction buffer and swirl the swab stick approximately 10 times. Press the head of the swab against the tube wall to release the antigen in the swab, and then let it stand for about one minute.

Install the drip tip on the extraction tube, close it tightly, and let it stand for about 1 minute.

Open the aluminium foil pouch, remove the test cartridge, add 3 drops (approximately 100 µl) to the sample port on the test cartridge (or add 100 µl using a pipette), and start the timer.

Wait for the coloured line (T) to appear. The result should be read in 15 minutes. Do not interpret the result after 20 minutes.
