The low-cost device can spot markers of the<strong> infectious diseases in 15 minutes from a finger prick of blood<\/strong>. It&#8217;s the first smartphone accessory that replicates all the functions of a laboratory-based blood test, according to the researchers.<\/p>\n<p>According with this device report, published Feb. 4 in the journal<em> Science Translational Medicine<\/em>, it was tested by health care workers in Rwanda who used it to analyze<strong> blood samples from 96 patients<\/strong>. The health care workers were given 30 minutes of training on the device, and 97 percent of the patients had a positive response to the device.<\/p>\n<p><em>&#8220;Our work shows that a full laboratory-quality immunoassay can be run on a smartphone accessory,&#8221;<\/em> team leader Samuel Sia, an associate professor of biomedical engineering at Columbia Engineering, said in a university news release.<em> &#8220;This kind of capability can transform how health care services are delivered around the world,&#8221;<\/em> Sia added.<\/p>\n<p>However, one expert was more cautious about the possibilities of the device. <em>&#8220;This is a new technology that uses smartphones to detect antibodies against <strong>HIV<\/strong> and <strong>syphilis<\/strong>. Although an encouraging development, there are significant limitations, such as comparison with confirmatory tests in standardized laboratories,&#8221;<\/em> said Dr. Ambreen Khalil, an infectious disease specialist at Staten Island University Hospital, in Staten Island, N.Y.<\/p>\n<p>Khalil noted that the device might work well in areas where it is hard to get adequate health care and medical resources are limited. <em>&#8220;It would be interesting to evaluate its performance in other settings as well,&#8221;<\/em> Khalil said.<\/p>\n<p>The dongle device \u2013 which are a small piece of hardware that attaches to a computer, or other electronic device in order to enable additional functions &#8212; is small and light enough to fit into a hand, uses little power and will cost about 34 USD to make, according to the researchers.<\/p>\n<p><em>&#8220;Our dongle presents new capabilities for a broad range of users, from health care providers to consumers,&#8221;<\/em> Sia said.<\/p>\n<p><em>&#8220;By increasing detection of syphilis infections, we might be able to reduce deaths by 10-fold. And for large-scale screening, where the dongle&#8217;s high sensitivity with few false negatives is critical, we might be able to scale up HIV testing at the community level with immediate antiretroviral therapy that could nearly stop <strong>HIV<\/strong> <strong>transmissions<\/strong> and approach elimination of this devastating disease,&#8221;<\/em> he added.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Through:<\/strong> <em>Health Library<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at Columbia University in New York developed a smartphone accessory that can detect HIV and syphilis.
