Paper test blood type

US scientists have just created a new blood test paper to help identify blood types that are only a few thousand dollars.

Just drop a drop of blood into the blood test paper, the paper will change color corresponding to a blood group. This paper can also be used to determine the blood type of an animal.

Determining blood type for patients is an important part of blood transfusion, to save the lives of millions of people around the world every year. Transmission of the wrong blood will cause death.

'Current methods of determining blood type often require many complex instruments, which many poor countries do not have,' said Gil Garnier, one of the scientists at the American Chemical Society.
