Scientists from the University of Utah have come up with a health card that is able to detect and test diseases rapidly, and these samples range from saliva to blood and urine. As samples are loaded on the card, it will automatically perform its magic and determine the type of disease and illness, courtesy of the giant magnetoresistance or GMR principle - similar to what is currently in use when hard drive reading is concerned. The health card itself is loaded with a bunch of disease markers for instantaneous test results - no more waiting for weeks on end while biting your nails. The current device is roughly the size of a desktop PC, but they are working on shrinking it further to the size of a credit card.
