Researcher micro-sizes genetics testing

September 22, 2008 | Source: PhysOrg.com

Using new “lab on a chip” technology, University of Virginia researchers hope to create a hand-held device that may eventually allow physicians, crime scene investigators, pharmacists, even the general public to quickly and inexpensively conduct DNA tests from almost anywhere, without need for a complex and expensive central laboratory.

Such a device could be used in a doctor’s office, for example, to quickly test for an array of infectious diseases, such as anthrax, avian flu or HIV, and for cancer or genetic defects. Currently, test tube-size fluid samples are sent to external labs for analysis, usually requiring a 24- to 48-hour wait for a result.

Home DNA test kits, possibly sold in pharmacies, would allow individuals to self-test for flu or other diseases.
