COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral surface.
COVID-19 rapid antigen tests (RATs) have been widely used for diagnosis of COVID-19. The World Health Organization (WHO) COVID-19 Case Definition states that a person with a positive RAT (also known as an antigen rapid diagnostic test or Antigen-RDT) can be considered a "confirmed case of SARS-CoV-2 infection" in two ways.

Quantification of RT-PCR products can largely be divided into two categories: end-point and real-time. [22] The use of end-point RT-PCR is preferred for measuring gene expression changes in small number of samples, but the real-time RT-PCR has become the gold standard method for validating quantitative results obtained from array analyses or ...
All COVID-19 tests start with a sample, but the scientific process goes very differently after that. Morsa Images/Digital Vision via Getty ImagesAt this point in the pandemic, you or someone you ...
A COVID-19 Rapid Antigen test(top) with a Covid-19 Rapid Antigen and a Influenza A&B Rapid Antigen Test(bottom) A rapid antigen test (RAT), sometimes called a rapid antigen detection test (RADT), antigen rapid test (ART), or loosely just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen.
This article is accurate as of press time. However, as the COVID-19 pandemic rapidly evolves and the scientific community’s understanding of the novel coronavirus develops, some of the ...
Public Health England announced a test on the 10th, [13] using a real-time RT-PCR (RdRp gene) assay based on oral swabs. [14] The test detected the presence of any type of coronavirus, including specifically identifying SARS-CoV-2. It was rolled out to twelve laboratories across the United Kingdom on 10 February. [15]
Samples are then shipped to a laboratory for RT-PCR testing. If samples come back positive for a specific pathogen, such as Covid-19, they undergo whole genome sequencing to determine variants.
