Antigen testing can be done at home, in primary health care facilities, at quarantine sites or at the appropriate place in the outbreak control area, depending on the type of antigen tested.
For example, for the new coronavirus antigen test, there are antigen test reagents for self-testing by residents; you can also go to a special window in primary care hospitals, where the price is $28 for single collection and $8 for mixed collection; and there are also temporary nucleic acid collection points in various places or sections of the outbreak control area, where collection is free of charge.
For Hepatitis B or HIV antigen testing, you need to go to a specialized department in the hospital.
The antigen test is an artificial labeling method using the specific binding between the antigen and the antibody, which is roughly divided into three steps: collection, testing, and judging the results, and needs to be completed by professionals.
