Disease Management: Blood tests via smartphone screens?
Source: AFP Relax News

Need a blood test? Soon you might be able to use your smartphone!

A micro-engineering laboratory at the Swiss Federal Institute of Technology (EPFL) has developed a diagnostic tool that performs blood tests via smartphone screens. The tool allows people undergoing anticoagulant treatments to easily test their blood at home, with the entire process taking mere minutes. Anticoagulants are used to stop blood clots from forming in the arteries and veins. Blocked arteries are serious health risks as they prevent oxygen from reaching certain parts of the body, resulting in strokes, pulmonary embolisms and heart attacks.

Those taking anticoagulants need their blood flow monitored regularly, and tests are usually performed in hospitals. The system developed by EPFL's Qloudlab eliminates the need for routine hospital visits, as test results are produced on smartphone screens.

Qloudlab CEO Arthur Queval told Wired.co.uk that the idea came to him in 2010 when the iPad launched. "My father just had a stroke and I thought the concentration of technology in smartphones/tablets could be useful for medical applications," he said. "This is where I came up with this idea to turn the electric field generated by the touchscreen to perform blood diagnostic testing."

The system requires placing a single-use, microstructured plastic layer of film on top of the device's screen. The newest prototype uses an unmodified Samsung Galaxy S4, however Queval is "confident" the team will make the film workable on other smartphones. Patients place one drop of blood on the film via "capillary action," which subsequently works with a molecule that causes coagulation. An app on the phone then scans the capacitive field for any disruptions. These changes are analyzed to ensure the patient doesn't have an an increased risk of bleeding, as anticoagulants thin the blood.

Queval noted that the team is still working on the accuracy of the test but that they have the potential to role it out to all major smartphones on the market

The tool could eventually be used to test for other blood conditions, such as blood glucose levels in diabetics. Qloudlab hopes to have the product ready for commercial use by 2015.
