Healthcare workers have created a smartphone dongle designed to detect STDs.
A team or researchers from Columbia Engineering created the device, which detects HIV and syphilis antibodies using a process called immunoassay.
Healthcare workers have to prick the finger of the patient and load the blood on to a cassette, which connects to the dongle.
After loading up the app on a smartphone, 15 minutes later a result is given indicating whether the patient has an STD.
Users are also guided by on-screen images throughout the process, meaning little training is required.
Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, said: “Our work shows that a full laboratory-quality immunoassay can be run on a smartphone accessory.
“This kind of capability can transform how healthcare services are delivered around the world.”
The device is estimated at $34 (£22) per dongle and is expected to help reduce costs of the conventional equipment used.
