Antigen Swab Test Kit Test Procedure

1. Blow your nose. Wash or disinfect your hands. Remove the test cassette by tearing open the foil pouch and place it in front of you.
2. Tear off the seal of extraction buffer tube, Press in the perforated hole on the top of the packaging and use the hole as a tube stand.
3. Remove the swab. Do not touch the sterile tip of the swab. Instead, grasp the swab by the handle. Insert the swab about 2.5 cm deep into your nostril until you feel resistance.

4. Collect sample from left and right nostrils with the same swab: Rub the swab against the inner wall of the nose and turn it at least 5 times to ensure sufficient sample is collected. Repeat the process in the other nostril.
Note: Children under 15 years of age (at least 2 years old), and people including the elderly and sick who are unable to perform the test themselves should be tested by another adult. To sample a child, insert a cotton swab into one of their nostrils until you feel some resistance (about 2 cm). Rotate the swab against the nasal wall 5 times. Repeat the sampling process by removing the swab and inserting the same swab into the other nostril. If the child feels any pain, do not continue the test.
5. Dip a cotton swab into the tube and make sure it is well mixed with the extract by stirring and dipping up and down at least 5 times. Let the cotton swab soak for a minute.
6. Slowly pull the swab out of the tube while gently squeezing the sides of the tube to retain as much liquid in the tube as possible.

7. Place the dropper tip firmly on the extraction buffer tube and mix the liquid thoroughly.
8. Drop 3 drops into the sample well (S) on the test card.
9. Interpret the test result between 15-20 minutes. The result after 20 minutes is invalid.

Interpretation of test results

Check that the wire is visible at the control wire (C). The color thickness of the control line (C) does not matter. If it is not visible, the test was not executed correctly and a new test must be executed with the new test set.

Ordinary type: with symptoms such as fever and respiratory tract, and pneumonia can be seen on imaging.

Heavy:

Adults meet any of the following:

· Respiratory distress, respiratory rate ≥ 30 breaths/min;

· In resting state, oxygen saturation ≤93%;

Arterial blood oxygen partial pressure (PaO₂)/inhaled oxygen concentration (FiO₂)≤300mmHg (1mmHg=0.133kPa), high altitude (over 1000 meters above sea level) area should be based on the following formula PaO₂/FiO₂ x [760/atmospheric pressure (mmHg) ].

In addition, if lung imaging shows that the lesions have progressed more than 50% within 24 to 48 hours, they are managed as severe.

Children meet any of the following:

· Persistent high fever for more than 3 days;

Shortness of breath (<2 months old, RR≥60 times/min; 2~12 months old, RR≥50 times/min; 1~5 years old, RR≥40 times/min; >5 years old, RR≥30 times/min /min), excluding the effects of fever and crying;

·Oxygen saturation ≤93% in resting state;

· Assisted breathing (groaning, alar flaring, three concave signs), cyanosis, intermittent apnea; drowsiness, convulsions;

· Rejection or feeding difficulties, with dehydration.

Critical:

One of the following conditions:

Respiratory failure occurs and requires mechanically assisted exhalation;

· Shock occurs;

· Combined with other organ failure requiring ICU monitoring and treatment.

Severe/critical high-risk groups

Older people over 60 years old; patients with underlying diseases; immunodeficiency; obesity (body mass index ≥ 30); women in late pregnancy and perinatal period; heavy smokers.
