U.S. APPROVES NEW BLOOD TEST TO SCREEN STROKE

A blood test already used to help screen for heart problems won U.S. approval to help predict a patient's risk for stroke, officials for the firm that makes it said. The Plac test, made by privately held diaDexus, scans the blood for high levels of the protein Lp-PLA2, which studies found were more common in stroke patients.
