China News Service, March 11. According to the official website of the National Health and Medical Commission on the 11th, after research, the State Council's comprehensive team of the joint prevention and control mechanism for the new coronavirus pneumonia epidemic decided to add antigen testing as a supplement on the basis of nucleic acid testing. "New Coronavirus Antigen Detection Application Scheme (Trial)".
Novel coronavirus antigen detection application scheme
(trial)
In order to guide the scientific and rational application of the new coronavirus antigen detection in various places, standardize the disposal management of positive antigen detection, and further improve the ability of "early detection", this plan is specially formulated.
1. Applicable people for antigen testing
(1) Persons who go to primary medical and health institutions for treatment, have respiratory symptoms, fever and other symptoms and have symptoms within 5 days.
(2) Isolation and observation personnel, including those in home isolation observation, close contact and sub-close contact, entry isolation observation, closed control area and control area.
(3) Community residents who need antigen self-testing.
2. Application of antigen detection in primary medical and health institutions
When primary medical and health institutions admit people with respiratory symptoms, fever and other symptoms within 5 days of onset of symptoms, institutions with nucleic acid detection capabilities should first conduct nucleic acid testing; those without nucleic acid detection capabilities should conduct antigen testing.
(1) The main conditions to be met.
In order to ensure quality and safety and avoid cross-infection between doctors and patients, primary medical and health institutions must meet the following conditions for antigen testing at the same time: 1. Sample collection and testing personnel should undergo biosafety training and technical operation training, and pass the assessment.
2. Have appropriate equipment such as biological safety cabinets, and protect medical personnel during the testing process.
3. The testing operation should be carried out in a relatively independent and well-ventilated space; primary medical and health institutions with laboratory conditions are encouraged to carry out testing operations in the laboratory.
4. Establish reporting, transport systems and workflows for those who have positive antigen tests.
(2) Disposal of test results.
1. For those who are positive in the antigen test, the primary medical and health institutions should immediately report to the disease control department under their jurisdiction, and the emergency center will transfer the antigen-positive people to the medical institutions that have set up fever clinics for nucleic acid testing in accordance with the guidelines for the transfer of people related to the new coronary pneumonia epidemic.
2. For those with negative antigen test, primary medical and health institutions should give symptomatic treatment, instruct them to observe at home, conduct antigen test once a day for 5 consecutive days from the date of consultation, avoid social activities, wear masks correctly, wash hands frequently and ventilate frequently.
If the antigen result remains negative until the symptoms disappear, other intervention measures may not be taken.
Once the antigen result is positive, the positive person must immediately report to the community (village) where he lives, and the community (village) will contact the emergency center to transfer them to a medical institution with a fever clinic for nucleic acid testing in accordance with the guidelines for the transfer of personnel related to the new coronary pneumonia epidemic; Sampling swabs, sampling tubes, test cards, etc. used by positive persons are put into sealed bags and transported to medical institutions for disposal as medical waste.
(3) Equipping of detection reagents.
Primary medical and health institutions equipped with antigen detection reagents are included in centralized bidding and procurement, which can continuously reduce the price of testing reagents and reduce the burden of testing costs through centralized procurement at the provincial level.
3. Application of Antigen Detection for Isolation Observers
Personnel in home isolation observation, close contact and sub-close contact, entry isolation observation, closed control area and control area shall be organized and managed by relevant management departments (such as communities, villages and towns, isolation points, etc.).
During the quarantine and observation period, nucleic acid testing shall be carried out in accordance with the requirements of the current relevant prevention and control plans, and antigen self-testing shall be carried out once a day for the first 5 days.
(1) The main conditions to be met.
The following conditions must be met for the isolation and observation personnel to conduct antigen testing: 1. Establish an antigen self-testing management process, including the collection of antigen testing reagents, personnel information verification, testing process supervision, and result reporting, etc.
2. Isolation observers need to read the instructions carefully, and conduct sampling, sample addition, and result interpretation in a standardized manner in accordance with the prescribed requirements and procedures; the management department with conditions should supervise and manage the testing process to ensure that the test results are authentic and credible.
3. Do a good job in waste disposal.
Sampling swabs, sampling tubes, test cards, etc. after testing, regardless of whether the results are negative or positive, are put into sealed bags and disposed of by management personnel in accordance with medical waste or according to procedures.
(2) Disposal of test results.
If the antigen test is positive, nucleic acid test must be carried out immediately to confirm.
(3) Equipping of detection reagents.
The management departments (such as communities, villages and towns, isolation points, etc.) that organize isolation and observation are responsible for the procurement, distribution, and management of antigen detection reagents.
4. Application of Antigen Detection for Community Residents
Community residents who have self-test needs can purchase antigen test reagents for self-test through retail pharmacies, online sales platforms and other channels.
(1) Matters needing attention.
In order to ensure the quality of sampling and testing, residents need to read the instructions carefully, and carry out operations such as sampling, adding samples, and interpretation of results in a standardized manner according to the prescribed requirements and procedures.
(2) Disposal of test results.
1. If the antigen test is positive, regardless of whether there are symptoms of respiratory tract, fever, etc., the residents should immediately report to the community (village) where they live, and the community (village) will contact the emergency center to transfer the residents to the set up according to the guidelines for the transfer of personnel related to the new coronary pneumonia epidemic. Nucleic acid testing is carried out in medical institutions in fever clinics.
Sampling swabs, sampling tubes, test cards, etc. used by positive persons are put into sealed bags and transported to medical institutions for disposal as medical waste.
2. If the antigen test is negative, asymptomatic residents can be closely observed, and antigen test or nucleic acid test should be carried out when necessary. Symptomatic residents are advised to go to a medical institution with a fever clinic as soon as possible to conduct nucleic acid test; if it is inconvenient to seek medical treatment, then You should self-isolate at home, avoid going out, and take an antigen self-test every day for 5 consecutive days.
5. Confirmation of nucleic acid detection
Nucleic acid testing is the basis for the diagnosis of new coronavirus infection.
In the process of nucleic acid test confirmation, if the nucleic acid test is positive, regardless of whether the antigen test result is positive or negative, corresponding measures will be taken according to the new coronavirus infection or confirmed new coronary pneumonia patient; if the nucleic acid test is negative but the antigen test is positive, it will be deemed as Those infected with the new coronavirus should take measures such as centralized isolation, close observation, and continuous nucleic acid testing.
6. Personnel training and publicity and education
In the process of applying antigen testing, all localities should do a good job in the training of medical staff in primary medical and health institutions, so that they can fully grasp the characteristics and operation points of antigen testing, so as to ensure accurate and reliable testing results, and provide patients and residents with relevant information on antigen testing. Knowledge dissemination and education.
When conducting antigen self-tests, the public should carefully follow the relevant basic requirements and procedures, and conduct nucleic acid tests to confirm when necessary.
