Instruction

Vazyme Antigen Rapid Test Principle

The double antibody sandwich method is adopted for this product to implement determination in the form of solid phase immunochromatography. The sample to be tested diffuses upward by capillary force at the sampling end, and when passing by the marker pad, the SARS-CoV-2 antigen in the sample is combined with the antibody on the marker pad to form a colloidal gold antibody-antigen complex. The complex continues to spread with the sample to reach the nitrocellulose membrane and is intercepted by the T-line (test line) coated with antibody, and the complex is captured to form an immune complex of colloidal gold antibody conjugates-antigen-coating antibody. The remaining colloidal gold conjugates continue to ascend and are combined with C-line (quality control line), indicating completion of the reaction.

Vazyme antigen rapid test specimen collection

9

Nasal swab

Make sure the nasal cavity is moist. The tip of the swab should be inserted between 3 and 4 cm until resistance is felt. Roll the swab along the inner wall of the nostril 5 times to ensure that mucus and cells are collected. Using the same swab, repeat this process for the other nostril to ensure that a feasible sample is taken from both nostrils. Remove the swab from the nasal cavity.

9

Nasolpharyngeal swab

A sampling operator gently lifts the head of the person from whom specimens are collected with one hand and holds the swab in the other hand, with the swab entering through the nostrils and slowly going deep backwards along the bottom of the inferior meatus. Excessive force should be avoided in case of traumatic hemorrhage due to arc-shape of the nasal meatus. When the tip of the swab reached the posterior wall of the pharyngonasal cavity, rotate it gently for one revolution (stop for a minute in the case of a reflex cough) and then slowly remove the swab and transfer it to an elution tube.

9

Oropharyngeal swab

The person from whom specimens are collected should first rinse the mouth with normal saline, and the sampling operator moistens the swab in sterile normal saline (the swab is forbidden to be put in virus preservation solution in case of allergy caused by antibiotics); and the person from whom specimens are collected lifts head slightly, with mouth opened, accompanied by an “Ah”sound, to expose the bilateral pharyngeal tonsils. Make the swab pass over the tongue root, wipe it back and forth with slight force on the bilateral pharyngeal tonsils of the person from whom specimens are collected for at least 3 times, and up and down on the posterior pharyngeal wall for at least 3 times, then transfer it to an elution tube.

Test procedure

1. Sample collection: Collect nasal swabs, nasopharyngeal swabs and oropharyngeal swabs according to the method of sample collection.
2. Remove the white cap from extraction reagent tube.
3. Insert the sample swab into the tube (immerse the sample part in the elution buffer), make sure the sample is removed into the buffer by rubbing and stirring the sampled swab up & down for 10 times.
4. Squeeze the tube and the swab to leave the eluent on the swab completely in the elution tube.
5. Mix the sample by gently turning the tube upside down, squeeze the tube to add 4 drops to the sample well of the reagent card, and start counting.
6. Visually read the result after 10 minutes. The result is invalid after 15 minutes.

Vazyme antigen test procedure

Inspection method

Please read the Instructions carefully before operation.

1. Recover the test strip and specimen eluent fully to the room temperature before use.
2. Take out the detection card from the aluminum foil bag and place it on a horizontal and dry plane.
3. After the specimen is collected, add it into 0.5 ml of specimen eluent, extract it up and down for at least 10 times (or at least 15 seconds), and finally squeeze the swab, removing the eluent completely from the swab and leaving it in the eluent tube and mixing the elute well.
4. Put on the upper cover of the elution tube, put it upside down on the sampling hole of the reagent card, gently squeeze the elution tube, and drip 4 drops into the sampling hole of the reagent card, and start timing.
5. Be sure to observe the detection card in 10 minutes after the test starts and judge the result. The results observed after 15 min are invalid.

Explanation of inspection results

Vazyme Test negative result

Negative

Only one red quality control line (C-line) is visible.

Vazyme Test positive result

Positive

Two (2) clear red lines are visible, one is quality control line (C-line), and the other is the T test line.

Vazyme Test invalid result

Invalid

There is only T test line, but no quality control line (C-line), suggesting that the item has a test error or the test result is invalid, and the item should be retested.

Vazyme Test invalid result

Invalid

There is no red line, suggesting that the item has a test error or the test result is invalid, and the item should be retested.
