Device detects heart attacks with one drop of blood

UCLA’s Chi On Chui has developed a device that brings lab quality bio-molecular assessments to point-of-care settings, such as clinics, ambulances or homes.

SELFA (Semiconductor Electronic Label-Free Assay) could reduce emergency room time for heart attack patients by hours. Similar to a diabetic glucose sensor, SELFA uses a single drop of blood, taken wherever symptoms occur, to determine which patients do not require further medical care.

According to Chui: “Eighty-five percent of patients who present with symptoms of acute coronary syndrome in emergency rooms across the U.S. and Europe — some 12.75 million per year — have actually not had heart attacks after a standard test comes back, hours later, from the lab.”
