A capacitive touch screen device forms a capacitance between a body part of a user and a sensor layer. The sensor layer of the device includes capacitive sensors that allow a current to flow to the body part from the device when contact is made. The body part contacts the device through a bodily fluid. The current drawn is measured and a value for the bodily fluid is determined. This value is compared against known values to diagnose a possible medical condition or to infer characteristics of the bodily fluid. |
