Both tests matter most after serious injury, when minutes count. Current methods depend on large machines, electricity and trained staff that are often missing in ambulances, disaster zones and remote clinics. The source does not say what stage the device has reached, so its path to patients is still unclear.

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. Hospitals measure both with large machines that need electricity and trained staff, which are often unavailable in ambulances, disaster zones or remote clinics.
