New smartphone technology reads cholesterol and vitamin D levels

Want to know your cholesterol and vitamin D levels? Use your smartphone.

In an ever growing list of cellphone functionality, researchers at Cornell University in Ithaca, New York are developing an add-on device that can measure the two, according to Karin Heineman with Inside Science.

"What this is really about is enabling you to obtain health information about yourself quickly," said David Erickson, a biomedical engineer at Cornel, who spoke with Heineman.

The device is a credit card shaped item that fits over your phone’s camera lens. With one drop of blood an app on the phone relays back cholesterol and vitamin D levels of the phone’s user.

“In two minutes it spits out…what your cholesterol level is today, right now," said Erickson.

Users of the device place a droplet of blood on a special chemical strip, take a snapshot of that strip, and then wait for a phone app to provide a reading, Heineman reports.

The technology also works with saliva and sweat. Erickson and his team hope to have the device on the market in the next couple of years.

Future use of the such technology could include reading for other vitamins and infectious diseases.
