" A new device that connects to smartphones can perform rapid HIV testing in the field, a potential breakthrough for\u00A0healthcare workers in places where the disease is near epidemic. The device, created by a Columbia Engineering team led by Samuel K. Sia, uses a blood finger prick method to simultaneously test for HIV and both active and non-active syphillis. Using what&amp;#039;s called the enzyme-linked immunosorbent assay method, the device\u00A0draws energy from the smartphone rather than an external battery. Users grip the device and place\u00A0a thumb into a replaceable plastic bulb, which draws the blood out more quickly. From there, the testing can be performed within 15 minutes, much like rapid HIV antibody testing used at clinics in the United States. The team says the testing is &amp;quot;full laboratory-quality&amp;quot; testing, and has been used in the field in Rwanda for\u00A0preventing mother-to-child HIV infection. The device costs just $34, which makes it easily affordable. Source: Medical Xpress "^^<http://www.w3.org/2001/XMLSchema#string>
