Rational Diagnostics

Rational Diagnostics is a biotechnology company specializing in functional precision medicine for oncology. Based in Erlangen, Germany, the company has developed a proprietary platform for functional drug sensitivity testing (fDST) that evaluates the response of a patient's live tumor cells to a wide range of anti-cancer therapies. Unlike traditional genomic testing, which predicts response based on DNA mutations, Rational Diagnostics' approach provides direct evidence of drug efficacy in a laboratory setting. This technology aims to assist oncologists in selecting the most effective treatment regimens for individual patients, particularly in cases of advanced or resistant cancers. The company is a spin-off from the University of Erlangen-Nuremberg and focuses on bridging the gap between diagnostic insights and clinical outcomes.
