The Alethia Group B Streptococcus (GBS) assay, performed on the Alethia Incubator/Reader, is a qualitative in vitro diagnostic for the detection of Streptococcus agalactiae in enriched cultures obtained from vaginal/rectal swab specimens from antepartum women. Enriched cultures are obtained by 18-24 hour incubation of vaginal/rectal swab specimens in selective broth medium, either Lim Broth, TransVag Broth or Carrot Broth.The Alethia GBS assay utilizes loop-mediated isothermal DNA amplification (LAMP) technology to detect Streptococcus agalactiae by targeting a segment of the Streptococcus agalactiae genome. Results from the Alethia GBS assay can be used as an aid in establishing the GBS colonization status of antepartum women. This assay does not diagnose or monitor treatment for GBS infections.The Alethia GBS assay does not provide susceptibility results. Culture isolates are needed for performing susceptibility testing as recommended for penicillin-allergic women.Alethia Group B Streptococcus is intended for use in hospital, reference or state laboratory settings. The device is not intended for nonlaboratory point-of-care use.
A collection of reagents and other associated materials intended to be used for the qualitative and/or quantitative detection of nucleic acid from Group B beta-haemolytic Streptococcus bacteria in a clinical specimen, using a nucleic acid technique (NAT).
