Realbio Technology (RBT) has cooperated with more than 300 business partners including hospitals, research institutes and well-known enterprises to provide a full range of technical services for a series of large-scale microbiological research projects and hundreds of related research projects. Based on hundreds of scientific research programs and medical projects, we have accumulated massive gut microbiome data  for different diseases that were derived from large Chinese-cohort studies, which helped us to gain rich R&D experience and lays a solid foundation for the development and improvement of the products for early disease screening and microecology intervention.
