Whole blood PCR testing preferable for West Nile virus detection
PCR-based West Nile virus testing using whole blood was effective and favored compared with plasma testing as an initial test for infection, researchers reported.
FDA grants emergency use authorization to first mpox PCR home test
The FDA has granted emergency use authorization for Labcorp’s Mpox PCR Test Home Collection Kit, the company announced in a press release.
In-house PCR testing for C. auris on admission leads to fewer hospital-onset cases
In-house PCR testing on admission for the detection Candida auris enabled researchers to identify more cases on admission and lowered rates of hospital-onset C. auris, a recent study showed.
PCR testing for congenital CMV produces ‘delightfully surprising’ results
PCR testing of dried blood spots demonstrated a high sensitivity to identify infants with congenital cytomegalovirus in a study conducted in Minnesota, the first state to mandate congenital CMV testing, researchers reported at IDWeek.
Multiplex PCR assay detects four respiratory viruses with single swab
HOUSTON — A multiplex PCR assay was able to detect and differentiate between four respiratory viruses — influenza A and B, respiratory syncytial virus and SARS-CoV-2 — researchers reported at ASM Microbe.
MRSA PCR nasal swab shows promise as stewardship tool
WASHINGTON — A MRSA PCR nasal swab showed promise as a tool for antimicrobial stewardship in a large study of pediatric critical care patients, according to findings presented here at IDWeek.
FDA authorizes Abbott’s monkeypox PCR test for emergency use
The FDA has issued an emergency use authorization to Abbott Molecular for its real-time PCR test for monkeypox using lesion swab specimens from those with suspected virus infection.
Will rapid tests ever fully replace cultures?
No. Used rationally, rapid nonculture tests can be a powerful complement to cultivating organisms. However, they will not fully replace cultures for the foreseeable future. Having an organism in hand allows phenotypic testing — most notably of antimicrobial susceptibility — and strain typing. Cultures can confirm results of rapid tests. They can provide insights not available by certain rapid tests, such as detection of organisms not included in a particular diagnostic panel. They can give noncorroborative data that are important in shaping interpretation of rapid test results and in guiding clinical decision-making.
Rapid diagnostics instrumental to patient care
Rapid diagnostic tests, now synonymous with COVID-19, are instrumental to patient care, helping to improve antimicrobial therapy, patient outcomes and even infection control, experts said.
