Juno Bio raised $3.8 million and opened a CLIA-certified sequencing lab in Oakland to scale its vaginal microbiome assay. The company said the test analyzes about 10,000 bacteria and fungi and also screens for four sexually transmitted infections. Juno reported selling more than 20,000 tests since launch and availability in 46 states, positioning the expansion to support both clinical testing capacity and pharmaceutical R&D partnerships using microbiome readouts.
