On the 12th, the State Food and Drug Administration issued a notice to approveNanjing Novizan, Beijing Jinwofu, Shenzhen Huada Yinyuan, Guangzhou Wanfu Biological , Beijing Huaketai Biological ‘s new crown antigen product self-test application application change. Since then, five new coronavirus antigen self-test products have been officially launched.
< span>Previously, the National Health and Medical Commission issued a notice that it decided to add antigen detection on the basis of nucleic acid detection as a supplement, and The organization has formulated “New Coronavirus Antigen Detection Application Program (Trial)”.
Who can self-assess? How to test yourself? Can self-test results replace nucleic acid results? Where can I buy self-tests?
Who can self-assess?
The protocol specifies three types of antigen detection groups:
- Persons who seek medical treatment in primary medical and health institutions, have respiratory symptoms, fever and other symptoms and have symptoms within 5 days;
- Isolation observation personnel, including home isolation observation, close and sub-close contact, entry isolation observation, closed control area and personnel in control area;
- Community residents who need antigen self-testing.
Where can I buy self-tests?
The project states that community residents have self- If you need testing, you can purchase antigen testing reagents for self-testing through retail pharmacies, online sales platforms, etc. channels.
Isolation observation personnelThe management department (such as community, village, town, isolation point, etc.) that organizes isolation observation is responsible for antigen Procurement, distribution and management of testing reagents.
What are the precautions for the self-test?
In order to ensure the quality of sampling and testing, residents must read the instructions carefully, and conduct sampling, sampling and testing in a standardized manner according to the prescribed requirements and procedures. Operations such as sample, result interpretation, etc.:
- Blow the nose with toilet paper, unpack the nasal swab, and avoid touching the swab with hands
- Tilt the head slightly, hold the swab in one hand and stick the end of the swab into one nostril, and slowly move backward along the bottom of the lower nasal passage. After penetrating 1-1.5 cm, stick to the nasal cavity and rotate at least 4 times (retention time not less than 15 seconds), and then use the same swab to repeat the same operation on the other nasal cavity;
- The nasal swab after sample collection is tested according to the instructions.
Once the antigen test is positive, residents should immediately report to their community ( Villages and towns) report, the communities (villages and towns) contact the emergency center, and transfer residents to medical institutions for nucleic acid testing in accordance with relevant work guidelines.
Can self-test results replace nucleic acid results?
No, nucleic acid testing is still the basis for the diagnosis of new coronavirus infection.
The “Basic Requirements and Procedures for Self-Testing of New Coronavirus Antigens” in the pilot program emphasizes that < span>Antigen detection is generally used in the acute infection period, that is, the sample detection within 7 days of the symptoms of the suspected population. Suspected population with positive and negative antigen results should undergo further nucleic acid testing. Positive results can be used for early triage and rapid management of suspected populations, but cannot be used as the basis for the diagnosis of new coronavirus infection.
