COVID-19 Antigen Test Kit CE Approved (Saliva Swab)

COVID-19 Antigen Test kit (Colloidal Gold) is a solid phase immunochromatographic assay for the rapid, qualitative detection of antigen to 2019 Novel Coronavirus in human saliva. This test provides only a preliminary test result. Therefore, any reactive specimen with the COVID-19 Antigen Test kit (Colloidal Gold) must be confirmed with alternative testing method (s) and clinical findings

MATERIALS SUPPLIED

Sealed pouches each containing a test cassette, a desiccant

Sampling cotton swabs (as saliva swab)

Antigen extraction buffer

Antigen extraction tube

Paper workbench (The small one-test-box can be used as a workbench)Instruction for use

STORAGE AND STABILITY

3. Do not use it if the tube/pouch is damaged or broken.

4. Wear protective gloves while handling specimens and wash hands thoroughly afterwards.

5. Avoid splashing or aerosol formation of specimen and buffer.

6. Clean up spills thoroughly using an appropriate disinfectant.

7. Decontaminate and dispose of all specimens, reaction kits and potentially contaminated materials (such as swab, extraction tube, test device) in a biohazard container as if they were infectious waste and dispose according to applicable local regulations.

8. Do not mix or interchange different specimens.

9. Do not mix reagent of different lots or those for other products.

10. Do not store the test kit in direct sunlight.

11. To avoid contamination, do not touch the head of provided swab when opening the swab pouch.

12. The provided swabs in the package should be used only for saliva specimen collection,

13. To avoid cross-contamination, do not reuse the swabs for specimen collection.

14. Do not dilute the collected swab with any solution except for the provided extraction buffer.

15. Test is for single use only. Do not re-use under any circumstances.

16. Do not perform the test in a room with strong air flow, such as electric fan or strong air-conditioning.

SPECIMEN COLLECTION

1. COVID-19 Antigen Test kit (Colloidal Gold) can be performed using saliva swab.

2. Testing should be performed immediately after specimen collection

3. Bring specimens to room temperature prior to testing.

4. If specimens are to be shipped, they should be packed in compliance with local regulations covering the transportation of etiologic agents.

5. Avoid chewing or swallowing during the sampling period. The saliva sample should be tested immediateły after sampling.

TEST PROCEDURE

Allow test cassette, Antigen extraction buffer, specimen and controls to equilibrate to room temperature (15-30°C) prior to testing.

1. Make sure there are no food residue in the mouth before sampling. If the patient just has eaten, gargle or tooth brushing is required. Remove the swab package, keep the swab on the tongue until the tip being fully soaking by saliva (at least two minutes).

2. Place the antigen extraction tube on the workbench. Place the antigen extraction buffer bottle vertically downward, squeeze the bottle to make the buffer drip freely into the antigen extraction tube without touching the edge of the tube, and add all of the antigen extraction solution (about 450ul) to the antigen extraction tube

3. Put the swab specimen into the antigen extraction tube pre-added with the antigen extraction buffer, and rotate the swab about 10 times while pressing the swab head against the tube wall to release the antigen in the swab then let it stand for about 1 minute.

4. Remove the swab while squeezing the tip of the swab so that as much liquid in the swab can be discharged as possible. Dispose of used swabs in accordance with biohazard waste disposal methods.

5. Install the dripper on the antigen extraction tube and cap it tightly, and let it stand for about 1 minute.

6. Remove the test cassette from the sealed foil pouch and use it as soon as possible. Place the test device on a clean and level surface

7. Place the test device on a clean and level surface

8. Transfer 3 drops (about 100μL) of mix Liquids to the sample well of the test card (or use a pipette to add 100μL) and start the timer.

9. Wait for the test result of the reagent. The result should be read in 15 minutes, Do not interpret the result after 20 minutes.
