Smartphone Mobile App tests for HIV Syphilis
Let’s be honest: Smartphones aren’t necessarily thought of as devices that help to slow the spread of sexually transmitted diseases. In fact, research has found that transmission rates go up when hookup sites – even ones on the tamer end, like CraigsList – come to town.
The dongle, as the team writes in the journal Science Translational Medicine, costs just $34 to make (an amount that could drop further if mass produced). It uses the phone’s power and data collection, and incorporates simple optics and fluid control to process a finger prick of blood.
The smartphone dongle uses a scientific test, ELISA commonly performed in clinical laboratories with equipment that costs almost $20,000 USD. The website at the University of Arizona contains an interactive animation displaying the clinical immunology of the antigen/antibody test for HIV.
