About

Starling Medical is a Houston-based medical device company building an at-home urine diagnostics and remote patient monitoring platform. Its UrinDx device installs in a patient's toilet and analyzes urine as part of the normal bathroom routine, sending results to a smartphone app and to Starling's clinical care team. The system is aimed at catching early changes that precede conditions such as recurrent urinary tract infections, and the company reports it is pursuing FDA clearance. Starling was a Y Combinator W22 company.

An indwelling toilet-based urine analyzer that captures daily diagnostic data with no change to patient behavior, paired with a nurse-monitored dashboard so urology and primary care practices can offer preventative monitoring under existing reimbursement.
