Faster way to test blood type developed

A team of Chinese scientists in Chongqing have developed a method to match a blood type within two minutes, according to a paper published in an international medical journal.

Blood typing is important for pregnancies, transfusions and transplants, but at hospitals the process takes about half an hour using centrifugal machines.

Nanomedicine researchers, led by Luo Yang, at the Southwest Hospital affiliated with the Third Military Medical University said that they have designed a dye-assisted paper-based procedure that is not only quicker, but also more cost effective.
