DNAE: This USB device performs HIV testing in less than 30 minutes.
Thanks to a joint development between Imperial College London and the company DNA Electronics, which consists of a small device that is able to detect HIV levels in the bloodstream. This small device allows to place a small sample of blood and later to be placed in a kind of USB pendrive, which will allow the information to be read either in a computer or in a mobile device, this through an application. Those responsible mention that the device works through a mobile phone chip, but they do not mention which or what type, which is able to identify the change in acidity in the blood and convert it into an electrical signal, which is translated by the application.
The device is not only able to identify the presence of HIV, but also determines the amount of virus present in the patient, which is very useful to measure the effectiveness of treatments, because with this the doctors will have an almost immediate vision Of changes in a patient, and thus know if they are not taking their medication or the treatment is not working. Nearly 1000 samples have been performed in patients with 95% accuracy in the results, which has led to the possibility of using this device to detect hepatitis and other types of virus.
The researchers say the results are available in 30 minutes, but the tests performed on average at 20 minutes. It should be noted that the device is disposable and the cost of doing it on a large scale could be even cheaper than the expense of a laboratory analysis, however, still need to perform more tests, but above all receive the necessary authorizations by Regulatory agencies around the world.
