J Clin Microbiol 2021 Apr 28. Epub 2021 Apr 28.

Lucira Health, Emeryville, CA, USA

Rapid and precise detection of -the leading global cause of sexually transmitted infections (STI)-at the point-of-care (POC) is required for treatment decisions to prevent transmission and sequelae including pelvic inflammatory disease, ectopic pregnancy, tubal-factor infertility and preterm birth. We developed a rapid POC test (POCT), termed LH-POCT, which uses Loop-mediated AMPlification (LAMP) of nucleic acids, and performed a head-to-head comparison with the Cepheid Xpert® CT/NG assay using clinician-collected de-identified paired vaginal samples from a parent study that consecutively enrolled symptomatic and asymptomatic females over age 18 years from the Ministry of Health and Medical Services Health Centers in Fiji. Samples were processed by the Xpert® CT/NG assay and LH-POCT, blinded to the comparator. Read More
