Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

People often talk about COVID-19 testing like it means only one thing. But in reality, the U.S. Food and Drug Administration (FDA) has so far granted emergency-use authorization to more than 200 ...

Antigen tests are one type of rapid test that may help diagnose COVID-19. Some rapid tests can provide results in 15 minutes. But, they may not be as accurate as other types of tests, such as a PCR ...

Currently established rapid methods for sterility testing of advanced therapy medicinal products (ATMPs) are mostly based on growth-based processes or the detection of metabolic activities. However, ...

PCR genetic analysis has been in the spotlight since COVID-19, but light is now further facilitating PCR-free methods. Osaka Metropolitan University scientists have developed a light-induced DNA ...

Tokyo — Researchers in Japan announced "game changing" research this week that found simple saliva tests for COVID-19 are just as reliable as the widely used, but more complicated and uncomfortable, ...

One of the best ways to figure out how far a virus like COVID-19 has spread in a community is to test for it. This step-by-step guide explains how coronavirus swab-the-nose-and-throat tests work, and ...

At-home PCR tests are just as accurate as those done in a lab. At-home antigen tests are more budget-friendly and give results quicker, but there is a greater chance of a false negative. As of ...

We evaluated PCR testing of filter tops from cages maintained on an IVC system through which exhaust air is filtered at the cage level as a method for detecting parasite-infected and -infested cages.
