An iPhone application that lets users check levels of blood, protein and other substances in their urine is the first target of U.S. regulators seeking boundaries in a burgeoning industry for medical diagnosis on-the-go.
Biosense Technologies Private Ltd.'s uChek system isn't cleared by the Food and Drug Administration and the agency said it wants to know why not, in a first-of-its-kind letter to a maker of a mobile-device application. The app relies on users, such as diabetics checking their glucose, to dip test strips in urine and use the smartphone's camera to allow the system to processes and generate automated results.
UChek works with test strips made by Siemens AG (SIE) and Bayer AG (BAYN), which are only approved for visual reading and require new clearance for automated analysis, the FDA said in the letter. The agency has said it wants stricter rules for apps that directly diagnose or treat conditions, proposing in 2011 to apply similar quality standards as for heart stents, ultrasound machines and other medical devices.
