What do we need to know about rapid test antigen?

The rapid antigen test requires an oropharyngeal or nasopharyngeal swab sample. rapid antibody test using a blood sample.
A rapid antigen test is often called an antigen swab. This test is considered more accurate than the antibody test because it can identify the virus in nasal and throat secretions.
The inspection can be done in a location that has a biosafety cabinet.
Rapid antigen testing can be used to detect people under surveillance (ODP) and patients under surveillance (PDP) in areas without testing facilities. Reverse chain reaction of transcriptase-polyumerase (RT-PCR).
Rapid antigen test only when put on screen Initially, the results have yet to be confirmed by the RT-PCR test.
It is also said that the antigen test can detect the corona virus protein when the virus in a person’s body is at the most infectious level.
2. Prices vary

In October, the WHO will distribute two antigen tests, the brand Abbott (United States) and SD Biosensor (South Korea) to several countries in cooperation with various institutions, such as the Bill & Melinda Gates Foundation.

3. US Studies on Rapid Antigen Testing

4. FDA Warning
Meanwhile, the United States Food and Drug Administration (FDA) has warned of a possible false positive result of a rapid antigen test to detect coronavirus infection, especially if the test was used incorrectly.
The FDA said it had received false positive reports from nursing homes and other health services.
According to the FDA, reading the test results, either before or after the time specified in the instructions, can show a false positive or negative.
This refers to the US antigen authorization provisions which stipulate that an authorized laboratory must follow the instructions for use regarding the administration of the test and the reading of the results.
Also, antigen tests that are not stored properly before use run the risk of giving false results.
Processing multiple samples at the same time can affect test results because it can be difficult to guarantee the correct incubation time for each sample.
“Take care to minimize the risk of cross contamination when testing patient samples, which can lead to false positive results,” the FDA said.
The FDA advises the Centers for Disease Control and Prevention (CDC) to recommend a protocol for antigen testing in nursing homes and to consider retesting to confirm results within 48 hours of testing. positive.
“In general, antigen tests are not as sensitive as molecular tests,” explains the FDA.
