Hand-cranked device reads blood type and hematocrit in one minute

Engineers built a hand-cranked, electricity-free device that determines blood type and hematocrit in about one minute. It targets ambulances, disaster zones and remote clinics that lack large lab analyzers and trained staff.

• Device runs without electricity or trained lab staff
