The new coronavirus pneumonia self-test box is a test product that has just been launched. It can detect whether the human body is infected with the new coronavirus pneumonia virus, which is of great help to the prevention and control of the new coronavirus pneumonia epidemic. Many people will use the new coronavirus pneumonia self-test box. . What is the principle of the new coronavirus pneumonia self-test box? How to use it?

What is the principle of the new coronary pneumonia self-test box

The principle of the novel coronavirus pneumonia self-test kit is antigen detection. Antigen detection is a direct detection of the unique protein (ie antigen) in the new coronavirus pneumonia virus, which can quickly detect whether the human body contains the new coronavirus pneumonia virus during the acute infection period, providing direct evidence of the new coronavirus pneumonia virus infection, and the operation is simple and fast. , which can be used for early triage and rapid management of suspected populations.

4. Insert the cotton swab into the previous reagent and turn it three or four times.

5. Cover the small test tube, align it with the round hole at the bottom of the new coronary pneumonia self-test box, and drop 2-3 drops.

6. Quietly wait for the results of the new coronavirus pneumonia self-test.

Precautions for the use of the new coronavirus pneumonia self-test box

1. In order to ensure the quality of sampling and testing, residents must read the instruction manual carefully, and conduct operations such as sampling, sample addition, and result interpretation in a standardized manner according to the prescribed requirements and procedures:

2. Blow your nose with toilet paper, unpack the nasal swab, and avoid touching the swab head with your hands;

4. According to the instructions for use of the reagent, place the nasal swab after collecting the sample in the sampling tube immediately. The swab head should be rotated and mixed in the preservation solution for at least 30 seconds. At least 5 times to ensure that the sample is sufficiently eluted in the sampling tube.

5. Squeeze the liquid from the swab head through the outer wall of the sampling tube by hand, and then discard the swab. After capping the sampling tube, drop the liquid vertically into the sample hole of the test card.

6. Once the antigen test is positive for novel coronavirus pneumonia, regardless of whether there are symptoms of respiratory tract, fever, etc., residents should be transferred to medical institutions for nucleic acid testing in accordance with relevant local work guidelines.
