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 ...

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 ...

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) ...

If you had COVID-19 symptoms in 2020, you probably would have masked up and braved a visit to a laboratory, doctor’s office, or clinic to get a polymerase chain reaction (PCR) test. A health care ...

With Omicron surging in the United States, many people are taking COVID-19 tests to see whether they test positive. Most people will take either a rapid antigen or PCR test. Though the PCR test is ...

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" ...
