Gemelli Biotech is a San Diego-based diagnostics company specializing in non-invasive precision tests for gastrointestinal diseases, including SIBO, IMO, excess hydrogen sulfide, and post-infectious IBS. Founded in 2018, the company leverages microbiome biology to develop clinically validated biomarkers that enable definitive detection and optimal treatment of common yet underdiagnosed GI conditions. With a focus on addressing the growing demand for microbiome-based diagnostics, Gemelli's products aim to replace traditional breath tests and invasive procedures. The company operates in a competitive but expanding market, driven by rising awareness of gut health and the microbiome's role in disease. While still private and early-stage, Gemelli's targeted approach and strong scientific foundation position it for potential growth through regulatory clearances, commercial partnerships, and expanded test menus.
