In research - Georgia Tech Team Claims 100 Percent Accuracy for Metabolomic Ovarian Cancer Test in Initial Trial ProteoMonitor GenomeWeb

........"In ovarian cancer, the single protein that's commonly used [as a biomarker], CA-125, is not a very accurate test," he said. "The reason for that is that all cancers are variable. So if you're relying on a single biomarker, it's very unlikely that that single biomarker will be 100 percent accurate or even 99 or 95 percent accurate."
"Even going from one to five [biomarkers] increases accuracy tremendously. In our case we're using at the minimum 2,000 to 3,000 features. That should in theory give us an even higher degree of accuracy," he said.
By comparison, most protein-based tests that are commercially available or under development use a handful of markers. Vermillion's OVA1, for example, analyzes five protein markers, including CA-125. The HealthLinx OvPlex test also uses five proteins, including CA-125, and the company is currently evaluating two additional markers to add to the test (PM 6/18/2010)....cont'd
