Antigen tests look for viral proteins rather than the genetic material of the virus. They cannot detect very small amounts of virus, so you need a higher amount of virus in your sample to get a positive result. This means you're most likely to get accurate results when you have the most virus in you

A test commonly used to identify the presence of starch in a sample is the iodine test. One of the two components of starch, specifically amylose, reacts with iodine to produce the dark blue color. While the presence of simple carbohydrates can also be detected using Benedict's solution, starches an

Rapid influenza diagnostic tests (RIDTs) are antigen detection tests that detect influenza viral nucleoprotein antigen. The commercially available RIDTs discussed in this document can provide results within 30 minutes or less. Thus, results are available in a clinically relevant time period to infor

The Rapid Influenza Diagnostic Test (RIDT) uses the detection of influenza virus nucleoprotein antigens to determine whether a person is currently infected with influenza. Commercially available RIDTs provide results within 30 minutes. These results can be observed by color changes or other visual s

Rapid antigen tests-how to use them effectivelyThe rise of the highly transmissible delta variant across the U.S. has increased demand for rapid antigen COVID-19 tests that can be purchased from a pharmacy without a prescription, used at home, school or work, and administered in 15 minutes results w

At this point in the pandemic, chances are you or someone you know has been tested for COVID-19 at least once. But do you know which test you took and the pros and cons of these different tests?Two main types of tests are used to diagnose SARS-CoV-2 infection: molecular tests (better known as PCR te

On 26 February, the government reminded members of the public to visit the dedicated COVID-19 website for information on selecting and using rapid antigen test (RAT) kits.Currently,there are many RAT kits on the market.The government accepts RAT kits approved by the relevant authorities in major ma

What is a saliva antigen test kit?Saliva COVID-19 Antigen Detection Kit (Colloidal Gold) is a non-invasive test that collects saliva in a collection tube with extraction buffer. In this way, two drops of the sample are applied to the test cartridge by the field inspection method.

In addition to the nucleic acid detection we are familiar with, there is also a new method called antigen detection.So what is antigen testing? What is the difference between antigen detection and nucleic acid detection?

Rapid Antigen Test - The Basics of the Test What is RAT for COVID-19 (RAT)?RATs are designed to directly detect SARS-CoV-2 virus proteins (antigens) in respiratory specimens.
