New device could deliver bedside blood test results in an hour

Go to the doctor to provide a blood sample and you’re typically faced with a needle and syringe and hours or even days of waiting to get results back from a lab. CU Boulder researchers hope to change that with a new handheld, sound-based diagnostic system able to deliver precise results in an hour with a mere finger prick of blood. The team describes the system in a new paper published Oct. 16 in the journal Science Advances.
