Molecular tests may be called polymerase chain reaction (PCR), RT-PCR, nucleic acid amplification test (NAAT), or LAMP test. How antigen testing works Antigen tests seek out specific proteins only found in the virus, which the body’s immune response recognises as 'foreign'. The antigen test goes looking for an antigen or a protein of the COVID 19 virus. Serology test is a sensitive analytical test that harnesses the unique properties of antibodies. The RT-PCR, reverse transcription polymerase chain reaction, is a molecular diagnostic test that detect the virus’s genetic material. Hi Everyone! PCR tests are very accurate when properly performed by a health care professional, but the rapid test can miss some cases. Antigen test. Antigen test samples are collected just like molecular tests, using nasal or throat swabs. All Rights Reserved. Antigen tests for SARS-CoV-2 are generally less sensitive than real-time reverse transcription polymerase chain reaction (RT-PCR) and other nucleic acid amplification tests (NAATs) for detecting the presence of viral nucleic acid. Both require lab processing and should not be confused with home-use "self-test" kits which are not sent away for lab processing. © 2018 MD Medical Group. Alternatively, the virus can be detected by the use of an antigen test. Currently, the Diagnostic or PCR tests are the most accurate ones out there, which makes them very reliable. Topic Molecular Test Antigen Test Antibody (Serology) Test Why is the test used? While antigen testing is becoming more common in … The two testing methods are now being used in India, and have been approved by the ICMR. “If you are testing people daily, the false negative rate is becoming less important because you are doing it over and over again,” Saag said. An antigen is a molecule found on the outside of a pathogen, capable of stimulating an immune response. Similar to RT-PCR tests, antigen tests diagnose active coronavirus infections and make use of nasal or throat swabs. Topic PCR Test Antigen Test Antibody (Serology) Test Why is the test used?
