Hand-cranked device tells blood type and red cell levels in 1 minute
When someone is badly injured, doctors urgently need two facts: the patient's blood type, so that a transfusion is safe, and their hematocrit, the share of the blood made up of red blood cells, which reveals blood loss or anemia.
AI Summary
A team led by Professor Chien‑Fu Chen at National Taiwan University created a hand‑cranked centrifuge that determines a patient’s blood type and hematocrit in about one minute. The device consists of a small plastic chip that spins using a manual crank and requires no electricity or trained staff. It operates with roughly 3 µL of finger‑prick blood. The findings were reported in the journal Biosensors and Bioelectronics.
