Due to the widespread of COVID-19 globally, the use of rapid antigen plays a crucial role as an alternative method for detecting positive-tested patients outside healthcare settings. Unlike molecular tests, such as RT-PCR, rapid antigen testing detects the presence of viral proteins using simple immunochromatography methods or lateral flow assays.
Rapid antigen tests assess the presence of viral proteins, making them different from serology tests. It looks for antibodies produced by the host in response to the infection. However, rapid antigen tests only assess acute illness, not a reaction to vaccination.
How does the test work?
Moreover, rapid antigen testing can be done outside the hospital laboratories and performed by the general public. It is inexpensive and straightforward to interpret compared to RT-PCR. Suppose you need a Rapid Antigen test for travel, this kind of testing is advisable since the turnaround time only takes about 15 minutes, applicable for people in a hurry since the test does not require a laboratory to analyze the results, unlike the PCR COVID-19 test.
Furthermore, an individual may undergo rapid tests when experiencing symptoms of COVID-19, which is considered more accurate. However, despite being quick with the results, it is not always correct. If you get a negative impact from the test and still experience COVID-19 symptoms, it would be better to get tested at a clinic and self-isolate.
How is rapid antigen testing different from another testing?
Compared to the standard polymerase chain reaction (PCR) test that can assure that someone is positive for COVID-19 virus with results available in approximately 24 hours, the rapid antigen test screens to identify positive cases earlier to prevent outbreaks potentially. Rapid antigen tests preclude the transmission of the virus to people. Also, a PCR test takes a deep nasal sample and throat sample to bring in laboratories for testing. While rapid antigen test, on the other hand, is done through a nasal or throat swab and placed into a liquid solution to spot on the proteins – if ever a protein is found, a person is currently positive with COVID-19 virus.
