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 ...

A new preprint describes a single-step molecular diagnostic test for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection caused by the Omicron variant that is behind ...

This study explores the effectiveness of toxin testing in predicting Clostridioides difficile infection (CDI) outcomes, revealing that patients with negative toxin results were less likely to ...

Researchers often call the polymerase chain reaction test – known as the PCR test – "the gold standard" for detecting the COVID-19 virus. The test is considered highly reliable and effective, and it ...

Last spring, a rapid polymerase chain reaction (PCR) test for COVID-19 — developed by Northwestern University spinoff company Minute Molecular Diagnostics — received emergency use authorization (EUA) ...

This decision, well within current norms for care, was nonetheless consequential: The president was forced to cancel a trip to advocate for legislation in support of the domestic semiconductor ...

Antibiotics have revolutionized medicine, saving countless lives by treating previously fatal bacterial infections with ease. Yet today, their power is in serious jeopardy. Every year in the United ...

The Centers for Disease Prevention and Control, or CDC, tweeted that "there’s a 10% chance" that people’s PCR tests were sent to laboratories across the country for genomic sequencing analysis.

A new biotechnology company in McKinney has ambitions to become the world’s first fully integrated platform for polymerase chain reaction (PCR) testing — the same technology behind a common COVID-19 ...
