CytoBay

CytoBay is a private cancer diagnostics company developing an AI-enabled cytology platform for non-invasive cancer detection and monitoring. Its core technology, Liquid ICC, is a patented liquid immunocytochemistry workflow that combines tumor-marker staining and cell morphology analysis on the same cytology slide, enabling improved visualization of suspicious cells in liquid samples. The company is building both an automated staining instrument for pathology laboratories and software-assisted analysis capabilities, with an initial focus on bladder cancer surveillance and screening. CytoBay has also described applications in breast cancer, lung cancer, and circulating tumor cell analysis. The business appears to operate as a platform diagnostics company rather than a therapeutics developer.
