Pattern Bioscience wants to put bacteria on the clock
A hospital can start antibiotics long before it knows which ones will work. Pattern Bioscience is building a test that watches individual bacteria respond, aiming to turn days of uncertainty into hours.
COPAN Diagnostics and the power of a better swab
A nylon tip is a modest place to begin a laboratory revolution. COPAN followed the specimen from collection to culture, building a business around the small steps that make a diagnosis possible.
Pearl Diagnostics, Inc.
Pearl Diagnostics is a Baltimore-based in vitro diagnostics company spun out of Johns Hopkins University that develops non-invasive urine tests to detect life-threatening lung infections. Its proprietary Smart Antibody technology identifies circulating microbial extracellular vesicles, and its lead product, the MycoMEIA Aspergillus Assay, became the first urine-based test to win FDA 510(k) clearance for aiding diagnosis of invasive aspergillosis. The company raised an $11.2M Series A in March 2026 to commercialize in the US and expand across Europe.
Karius
Karius is a Redwood City, California life-sciences company that turns a single blood draw into a broad infectious-disease diagnosis. Its flagship Karius Test uses microbial cell-free DNA (mcfDNA) sequencing, metagenomics and AI to detect more than 1,000 pathogens - bacteria, DNA viruses, fungi and parasites - often within a day of receiving a sample. Founded in 2014 out of Stephen Quake's lab at Stanford, the company aims to give clinicians a fast, non-invasive alternative to invasive biopsies and slow cultures, with a focus on the immunocompromised patients who need answers most urgently.
