Stanford University scientists say they have developed a new test for type 1 diabetes that will cost a fraction of the current price and could speed up diagnosis from days to hours. That could be useful anywhere, but especially in poorer countries where many people with diabetes go undiagnosed or misdiagnosed because the existing tests are too expensive to be widely offered.
In current tests, blood samples are sent to a lab, where radioactive materials are used to detect the cause of the disease: a so-called auto-antibody that attacks the insulin-producing cells in the pancreas. This test is labor-intensive and costs hundreds of dollars.
