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, ...

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 ...

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 ...

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 ...
