The U.S. FDA handed good news to Healthy IO Ltd. (Healthy.io) with 510(k) clearance for its smartphone-based Minuteful Kidney test, making kidney function testing – from sample to result – possible at home. The app calculates the albumin-to-creatinine ratio (ACR), a key indicator of kidney disease. By enabling people to complete the test using their phones, the company says it has increased the rate of testing in high-risk patients by 50%.
