What are the steps of antigen self-test
1. Preparation before antigen self-test
Wash your hands. Wash hands with flowing water or hand disinfectant.
Understand the testing process. Carefully read the supporting instructions of antigen self-test reagent and precautions related to antigen self-test.
Reagent preparation. Check whether the antigen self-test reagent is within the shelf life, and check whether the contents such as nasal swabs, sampling tubes and test cards are missing or damaged. If the reagent expires or the contents of the reagent are missing or damaged, the test reagent shall be replaced in time.
Confirm the environmental temperature and humidity requirements of the test. The colloidal gold test strip is generally required to be tested at 14-30 normal temperature to avoid abnormal test results caused by supercooling, overheating or excessive humidity. The antigen detection card shall be placed in a flat and clean place after the package is removed.
2. Sample collection
Those over 14 years old can take nasal swab samples by themselves. The self inspector first blows his nose with toilet paper. Carefully unpack the nose swab and avoid touching the swab head with your hands. Then tilt your head slightly, hold the tail of the swab in one hand and stick it to one side of the nostril to enter, slowly penetrate 1-1.5cm backward along the bottom of the lower nasal tract, then stick it to the nasal cavity and rotate it for at least 4 turns (the residence time shall not be less than 15 seconds), and then repeat the same operation for the other nasal cavity with the same swab.
Those aged 2-14 years should be sampled by other adults. When sampling, first blow your nose with toilet paper, and then tilt your head slightly. The sampling personnel shall carefully unpack the nasal swab, avoid touching the swab head with their hands, gently hold the head of the person to be collected with one hand, stick the swab into one side of the nostril with the other hand, slowly penetrate 1 cm backward along the bottom of the lower nasal tract, and then rotate the nasal cavity for at least 4 turns (the residence time shall not be less than 15 seconds), and then repeat the same operation with the same swab for the other nasal cavity.
3. Antigen detection
Put the nasal swab immediately after collecting the sample into the sampling tube. The swab head should be rotated and mixed in the preservation solution for at least 30 seconds, and squeeze the swab head by hand across the outer wall of the sampling tube for at least 5 times.
Squeeze the liquid of the swab head through the outer wall of the sampling tube by hand, and then discard the swab. After the sampling tube is covered, drop the liquid vertically into the sample hole of the detection card.
Read the results after waiting for a certain time according to the reagent instructions. Positive results: both “C” and “t” show red or purple bands, and the bands at “t” can be dark or light, which are positive results. Negative results: red or purple bands are displayed at “C” and no bands are displayed at “t”. Invalid result: no red or purple band is displayed at “C”, regardless of whether the band is displayed at “t”.
