A new test that can quickly tell doctors what kind of virus is making patients sick, and may reduce the use of unneeded antibiotics, was approved Thursday by the Food and Drug Administration.
Expected to be used by hospital labs and in private medical practices, the test identifies 12 respiratory viruses or subtypes, including several types of influenza and rhinovirus — which causes the common cold — in hours, rather than days.
Normally, hospital labs test for viruses by growing them in culture, which can take four days or more. The new test, xTAG Respiratory Viral Panel, developed by Toronto-based Luminex Molecular Diagnostics, can more rapidly identify a virus even at low levels, says Mark Kolins, Chief of Clinical Pathology and Medical Director at the Beaumont Reference Laboratory in Beaumont Hospital, Detroit. Kolins, who tested the viral panel in clinical studies, says it represents an "enormous change," because it will reduce the likelihood that a doctor prescribes antibiotics for an infection caused by a virus. Bacteria respond to antibiotics, but viruses don't.
Luminex Vice President Jeremy Bridge-Cook, says when doctors treat respiratory infections, they prescribe antibiotics more than half the time, "even though 80% of the time those respiratory infections are viral. This test will help reduce unnecessary use of antibiotics," he says, and will guide other treatment decisions, such as whether to isolate patients.

For those of you in the know, its Luminex! I am verrry familiar with this technology and I can say its a pretty accurate test (and very cool technology):thumbsup:
