A novel diagnostic tool developed by a CMU spinoff hopes to give doctors a fast and inexpensive way to diagnose life-threatening diseases. Accel Diagnostics was founded by Dr. Alberto Gandini, CEO, and Dr. James Antaki, a professor of biomedical engineering at CMU. The AlphaLab startup recently received a GAP grant from CMU to complete work on a beta version of the handheld tool, the size of a credit card, which is capable of accurately diagnosing one of several proteins in patients.
