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 ...

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 ...

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 ...

Northwestern scientists have created the fastest-ever hepatitis C diagnostic, delivering accurate results in only 15 minutes. The test uses the DASH rapid PCR system, originally developed for COVID, ...

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 ...

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) ...

The fastest ever test for hepatitis C - taking just 15 minutes - could save millions of lives, according to new research. It provides results up to 75% faster than current rapid tests and paves the ...
