The most common sample types are: Swab samples use a swab (similar to a long Q-Tip) to collect a sample from the nose or throat. Both of these testing methods are used to detect DNA or RNA, which is an essential component of all cells. Some tests provide results rapidly (within minutes); others require 1-3 days for processing. Refers to point-of-care antigen tests only. More research is needed to determine what, if anything, antibody tests can tell us about a persons immunity. "The NAAT procedure works by first amplifying or making many copies of the virus's genetic material that is present in a person's specimen," according to the CDC. While most of the available COVID-19 tests utilize this common approach, there are differences.

In the following post, well cover common questions about a variety of COVID-19 tests and describe how Labcorp is helping researchers and patients alike to fight this virus. Amplification of genetic material can also be done through techniques like a ligation chain reaction and branched DNA reaction (quantiplex b DNA) in the NAAT procedure. Public health surveillance testing may sample a certain percentage of a specific population to monitor for increasing or decreasing infection rate or to determine the population effect from community interventions. NAATs detect genetic material (nucleic acids). Both are extremely important in detecting infectious diseases and saving the lives of millions of people around the world. Based on evolving evidence, CDC recommends fully vaccinated people get tested 5-7 days after close contact with a person with suspected or confirmed COVID-19. 7 NAATs that use multiple targets are less likely to be impacted by an increased prevalence of genetic variants. While many countries require PCR tests to enter, some allow for rapid antigen tests in their place, including Jamaica and Belize. PCR would be chosen where there is a low likelihood of having the virus, but we want to be certain the patient doesnt have it.

Understanding COVID-19 tests, including the different types of tests and their uses, and the types of samples the tests use, is key to making an informed decision that meets your needs. Antigen tests are based on the principle of antigen-antibody interaction. Additionally, while the CDC requires all international travelers to get a test within three days of boarding a flight to the U.S., rapid viral tests are acceptable. Furthermore, antigen tests are typically less specific and less sensitive than NAAT tests. They help us to know which pages are the most and least popular and see how visitors move around the site.

Table 1 summarizes some characteristics of NAATs and antigen tests to consider for a testing program. Antigen tests are less sensitive than NAAT tests. An antigen test looks for proteins on the virus and requires more virus to be present and therefore will be detected later in the course of illness. NAAT, PCR, biosensor, and LCR are several techniques used in laboratories to amplify the genetic material of the pathogen.
