How to operate the COVID-19 test?

With the advancement of medical treatment and the continuous efforts of medical researchers, a new coronavirus antigen self-test kit has been developed. People who meet the relevant testing indications can read the operating steps and precautions carefully. , operate it in a standardized manner, and the self-test can usually be completed in 1 minute.

1. Applicable people:

1. People with obvious symptoms: those who have obvious respiratory symptoms, such as dry throat, cough, wheezing, accompanied by fever symptoms, and symptoms 5 Persons within days;

2. Quarantine observers: including people under home quarantine observation, close contact and sub-close contact, entry quarantine observation, people in closed and controlled areas;

3. Antigen detection: Insert the swab into the sample extraction tube, break the swab at the break point, tighten the colored cap and let it sit for 1 minute, then unscrew the transparent cap on the top of the extraction tube and insert it into the sampling hole. Add 4 drops of sample solution and observe the results after 10-15 minutes.

3. Test results:

1. Positive result: Both "C" and "T" on the test card show red or purple strips, and the color of the strip at "T" It can be deep or shallow, both are positive results;

Positive results can be used for early triage and rapid management of suspected people. They can only be used as supplementary evidence to confirm the new coronavirus infection, and cannot be used as a basis for diagnosis. The nucleic acid test results will still prevail.
