The Solana GBS assay is an in vitro diagnostic test for the direct, qualitative detection of group B Streptococcus from vaginal/rectal swabs following 18 to 24 hours incubation in LIM or Carrot broth cultures.
The assay utilizes helicase-dependent amplification (HDA) for the amplification of a highly conserved fragment of the Thiolase (atoB) gene sequence and is intended for use only with the Solana instrument.
An overnight LIM or Carrot broth culture enriched from a swab is lysed by simple heat treatment, aliquoted and added to a Reaction Tube containing lyophilized mix of HDA reagents including primers specific for the amplification of a fragment from the conserved region of the Thiolase (atoB) DNA.
The target sequence is amplified inside Solana by specific primers and detected by a specific fluorescence probe included in the Reaction Tube. A competitive process control (PRC) is included in the Lysis Tube to monitor sample processing, inhibitory substances in clinical samples, reagent failure or device failure. The PRC is amplified by the target-specific primers and detected by a PRC specific fluorescence probe.
Results are displayed on the touchscreen, can be saved to the instrument, printed, and are capable of being sent to the LIS and exported through one of Solana’s four USB ports. Solana GBS is supported by the power of the Virena® System
