TrueBac™ ID

A cloud system that incorporates the “gold standard” of bacterial identification by using whole genome sequences.

World’s first genome-based diagnostic system that can identify >10,000 species with unprecedented accuracy. A clinical evaluation study has shown that TrueBacTM ID identified 94% (34/36) of clinical isolates that were not identified by MALDI-TOF systems (Ha et al. 2019).

  • Institutions that sequence bacterial genomes regularly.
  • Companies that produce probiotics products where quality control of their bacterial strains are essential.
  • Medical facilities that investigate pathogens.
