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 ...

COVID-19 tests are in greater demand than ever, and new data about the Omicron variant can make picking and using different types of tests confusing. Molecular tests for COVID-19, like the "RT-PCR" ...

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 ...

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 ...

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) ...

A PCR test is often considered the gold standard for detecting coronavirus infection. It’s the test some employers want employees to take before returning to work after having Covid-19, and the one ...

A false positive result is possible with a rapid COVID-19 test. It happens when a person does not have COVID-19 but still tests positive for the disease. People can use a rapid COVID-19 test at home ...
