Nov 9, 2021 · Two major types of tests are used to diagnose infection with SARS-CoV-2: molecular tests – better known as PCR tests – and antigen tests. Each detects a different part of the virus, and how it works influences the test’s speed and relative accuracy. So what are the differences between these types of tests?
Mar 18, 2024 · Antibody tests detect specific antibodies that target different parts (nucleocapsid or spike protein) of the virus. Detection of anti-nucleocapsid antibody indicates SARS-CoV-2 infection, while anti-spike protein antibody may be induced by COVID-19 vaccination or by SARS-CoV-2 infection.
There are currently two primary types of COVID-19 tests being used to test patients for COVID-19: molecular tests (also known as nucleic acid, RNA or PCR tests) and rapid antigen tests.
May 14, 2024 · Molecular tests. These tests look for genetic material from the COVID-19 virus. Polymerase chain reaction tests, shortened to PCR tests, are molecular tests. You may also hear this type of test called an NAAT test, short for nucleic acid amplification test. PCR tests are more accurate than the other type of COVID-19 test, called an antigen test.
Dec 20, 2023 · Serologic or Antibody Testing for Diagnosis of SARS-CoV-2 Infection. Unlike NAATs and antigen tests, which detect the presence of SARS-CoV-2, serologic or antibody tests can detect recent or prior SARS-CoV-2 infection or vaccination.
Dec 16, 2022 · Key Points: Antibody tests have public health value for monitoring and evaluating population levels of immunity, as well as clinical utility for patients. Antibody tests that have received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) may be used for both public health and clinical purposes.
