Cards loaded with blood or urine samples can be scanned in minutes

Scientists have designed a sensitive prototype to test dozens of disease simultaneously by scanning a card loaded with microscopic blood, saliva or urine samples.

Unlike lab tests today, results could be available in minutes, not hours to weeks. The prototype works on same principle givant magnetoresistance or GMR that reads data on computer hard drives or listen to tunes on portable digital music players. Read more
