A 10-Cent Blood-Type Test
June 9, 2010 | Source: Technology Review
Researchers at Monash University have developed the first dipstick-type test to determine blood type.
The test involves putting a drop of blood onto a thin piece of paper that has been specially printed with antibodies; as the blood seeps into different parts of the paper, the blood type is revealed. The researchers say the test, which costs pennies, could improve medical treatments in the developing world.
