New technology in development, a card that you would swipe just as is done with credit cards. As listed below the card could give instant information relative to PSA testing, Herpes, and markers with personalized medicine. The results would be within a few minutes instead of days or even weeks as we have with some test today.
The technology is using the same principles use on a PC today with hard drives and MP3 players, so someday we could look at a multi purpose MP3 player/medical test device?
It also has environmental implications as well to find bacterial in water for a simple example. The card when finished could hold up to 1900 samples for testing. Amazing technology in the works, and here I am just hoping to have my medical information on a card I could swipe, and this goes much further than just data! BD
University of Utah scientists successfully created a sensitive prototype device that could test for dozens or even hundreds of diseases simultaneously by acting like a credit card-swipe machine to scan a card loaded with microscopic blood, saliva or urine samples.
The prototype works on the same principle – giant magnetoresistance or GMR – that is used to read data on computer hard drives or listen to tunes on portable digital music players.
"Think how fast your PC reads data on a hard drive, and imagine using the same technology to monitor your health," says Marc Porter, a Utah Science, Technology and Research (USTAR) professor of chemistry, chemical engineering and bioengineering.
The prototype card-swipe device consists of a GMR "read head" and sample stick. Right now, the device is about the size of a PC. But Granger says that when it is developed commercially, the GMR sensor device will look like a credit card reader.
