growth-positive

Ruby, an AI-based application, has conducted over a million tests to assess hemoglobin levels in the blood, offering a simple and accessible alternative to traditional blood tests for diagnosing anemia. A new study published in the prestigious journal PNAS shows that its accuracy is comparable to that of a regular blood test. The application allows users to take a photo of their fingernail with a smartphone to get a numerical estimate of hemoglobin levels within seconds. This innovation addresses the widespread issue of anemia, affecting over two billion people worldwide, by providing a convenient at-home diagnostic tool.
