Finger Prick HIV Test Next Year?

Just read this interesting news. Using a PDA and a drop of blood on a chip, an instant reading.

"A test that can deliver diagnosis during one doctor visit would be a major breakthrough for regions like sub-Saharan Africa, where 25 million people are living with HIV. Current tests require technicians to draw a blood sample, then ship it to a central lab where trained personnel use expensive equipment to determine the result. Locating the patients afterward can be difficult, because they often travel from remote regions to visit health clinics.

The new test works by dropping a patient's blood sample onto a plastic biochip, which detects elements in the blood, says John McDevitt, the University of Texas chemist who helped develop the technology. The card is then inserted into a toaster-size analyzer, which determines the CD4 cell count."
