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 ...

There are three different ways to test for COVID-19: PCR tests, antigen tests and antibody tests. Each method is best for a different stage of COVID-19 infection. Used in sequence, all three methods ...

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, ...

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 ...

A dried 5′-phosphorylated synthetic oligonucleotide for Caenorrhabditis elegans-miR-39 (C.elegans-miR-39) (Integrated DNA Technologies) (5′-phos--3′), with a known starting concentration of 7.6 nmol ...

Certain serious fungal infections occur in regions of the United States with specific environments and are often tied to soil ...

Posts circulating on Facebook and Instagram claim the Centers for Disease Control and Prevention will stop using its COVID-19 test because it cannot differentiate between the COVID virus and flu ...

A digital polymerase chain reaction (dPCR) technique for screening malaria parasite genomes will help identify when they have mutations that allow them to dodge detection by some rapid tests, shows a ...

Soiled-bedding sentinels are not always efficient in detecting pathogens in rodent colonies. In this context, PCR-based testing can be more sensitive and is being advocated as adjunct to traditional ...
