This isn't a tricorder other than by the journalist's imagination. Sadly it is more limited than that article or related news releases indicate. At present it only includes a means of detecting anti-HIV antibodies or syphilis markers, with a variant that can detect prostate disease markers.
There's a more meaningful description of the device here:
Simply nicknaming a device a tricorder doesn't make it anything like one, and the name has been applied to other commercial devices such as Vital Technologies Corporation's official tricorder, which simply included a few meters and a clock, and there have been others.
Rather than illustrating a connection between Star Trek and 'real science' this serves to demonstrate how much Star Trek has penetrated the popular imagination. Lab-on-a-chip (LOC) devices are becoming more common but they also suffer a variety of drawbacks such as a reduction in accuracy compared with conventional analysis.
