In order to guide the scientific and rational application of the new coronavirus antigen test, standardize the disposal management after a positive antigen test, and further improve the "early detection" ability, this program is formulated.
One, antigen test applicable population
To the primary health care institutions, accompanied by respiratory, fever and other symptoms and the emergence of symptoms within five days.
People under quarantine observation, including those under home quarantine observation, close and sub-confinement, inbound quarantine observation, sealed and controlled areas and control areas.
Community residents with antigenic self-testing needs.
Second, the application of antigen detection in primary health care institutions
Primary health care institutions in the reception of respiratory, fever and other symptoms and the emergence of symptoms within five days of the person, with the ability to detect the nucleic acid testing institutions should be preferred to carry out nucleic acid testing; does not have the ability to detect the nucleic acid testing, antigen detection.
The main conditions to be met. In order to ensure quality and safety, to avoid cross-infection between doctors and patients, primary health care institutions to carry out antigen detection need to meet the following conditions: 1. Sample collection, testing personnel should be trained in biosafety and technical training, and qualified. 2. With biological safety cabinets and other appropriate equipment, testing process to do a good job of protection of medical personnel. 3. Detection of the operation of the relatively independent and well-ventilated space; the primary health care institutions should be preferred to carry out nucleic acid testing; not nucleic acid testing capacity to carry out antigenic testing. Space; primary health care institutions with laboratory conditions, to encourage testing operations in the laboratory. 4. The establishment of antigen detection of positive personnel reporting, transfer system and workflow.
Disposition of test results.
1. For antigen test-positive personnel, primary health care institutions should immediately report to the jurisdiction of the CDC department, the emergency center in accordance with the new crown pneumonia epidemic related personnel transfer work guide, the antigen-positive personnel will be transported to the establishment of fever clinic of the health care institutions for nucleic acid testing.
2. For antigen-negative persons, primary health care institutions should provide symptomatic treatment, instruct them to stay at home for observation, conduct antigen testing once a day for five consecutive days from the day of consultation, avoid social activities, wear masks properly, and wash their hands and ventilate their homes diligently. If the antigen result is negative until the symptoms disappear, no other interventions can be taken. Once the antigen result is positive, the positive person needs to report to the community immediately, and the community will contact the emergency center in accordance with the guidelines for the transfer of people related to the new coronary pneumonia outbreak, and transfer them to the medical institutions that set up fever clinics for nucleic acid testing; the sampling swabs, sampling tubes, and test cards used by the positive person will be put into a sealed bag and transferred to the medical institutions for disposal as medical wastes.
Testing reagents are equipped. Primary health care institutions equipped with antigen detection reagents into the centralized bidding and procurement, can be through the provincial centralized recruitment and procurement, and constantly reduce the price of testing reagents, reduce the burden of testing costs.
Three, isolation and observation of personnel antigen detection application
Home isolation and observation, close and sub-confinement, entry isolation and observation, sealing and control areas and control areas of the personnel, by the relevant management department to do a good job in the organization and management. Nucleic acid testing is carried out during the isolation observation period in accordance with the current requirements of the relevant prevention and control programs, and antigen self-testing is conducted once a day for the first five days.
Main conditions to be met. Isolated observation personnel to carry out antigen testing need to meet the following conditions at the same time: 1. Establishment of antigen self-testing management process, including antigen test reagents, personnel information verification, testing process supervision, results reporting, etc. 2. Isolated observation personnel need to carefully read the instructions, in accordance with the specified requirements and procedures, standardized sampling, sample addition, results interpretation and other operations; the management department with the conditions of the testing process to carry out Supervision and management to ensure that the test results are true and credible. 3. Testing after the use of sampling swabs, sampling tubes, test cards, etc., regardless of whether the results are negative or positive, are packed into a sealed bag by the management of reference to medical waste or according to the program.
Disposal of test results. Positive antigen test shall be confirmed by nucleic acid test immediately.
Testing reagents. The management department that organizes the isolation observation is responsible for the procurement, issuance and management of antigen detection reagents and other related work.
Four, community residents antigen test application
Community residents with self-testing needs, through retail pharmacies, online sales platforms and other channels, to purchase their own antigen test reagents for self-testing.
Matters to note. In order to ensure the quality of sampling and testing, residents need to read the instructions carefully and follow the prescribed requirements and procedures to standardize the sampling, spiking, and result interpretation operations.
Disposition of test results.
1. Positive antigen test, regardless of whether there are respiratory, fever and other symptoms, residents should immediately report to their community, the community contacted the Emergency Center in accordance with the guidelines for the transfer of people related to the new crown pneumonia outbreak, the residents will be transferred to the set of fever clinic of the medical institutions, nucleic acid testing. Sampling swabs, sampling tubes, test cards, etc. used by the positive persons are put into sealed bags and transported to medical institutions for disposal as medical waste.
2. Negative antigen test, asymptomatic residents can be closely observed, and then antigen test or nucleic acid test when needed; symptomatic residents, it is recommended that as soon as possible to set up a fever clinic medical institutions, nucleic acid test; if inconvenient to consult the clinic, you should be self-isolation at home, to avoid going out, and five consecutive days once a day to conduct a self-assessment of antigen.
V. Confirmation of nucleic acid testing
Nucleic acid testing is the basis for confirming the diagnosis of new coronavirus infection. In the process of nucleic acid test confirmation, if the nucleic acid test is positive, regardless of the antigen test results are positive or negative, according to the new coronavirus infection or the new coronary pneumonia diagnosis of patients to take appropriate measures; if the nucleic acid test is negative but the antigen test is positive, it is treated as a new coronavirus infection to take centralized quarantine and other measures to be closely observed, and consecutive nucleic acid test.
Sixth, personnel training and publicity and education
All over the application of antigen detection process, we must do a solid job of primary health care institutions in the training of medical personnel, so that they fully grasp the characteristics of the antigen test and the main points of the operation, in order to ensure that the results of the test is accurate and reliable, and to the patient and the residents of the antigen test to do a good job in the publicity of the knowledge of publicity and education. When conducting antigen self-testing, the public should carefully follow the basic requirements and procedures, and when necessary, conduct nucleic acid testing for confirmation.
