    Signature Diagnostics Detector C blood test

    completely agree (and reposting) --

    this is the fourth blood-based colon cancer screening test that has come along. So far, all have been flops and I fully expect this one will as well.

    It's simply not possible to obtain enough mutated DNA from colon cells via the blood stream. If it were possible, Conroy's Invader technology would probably be the best situated - i.e. EXAS already has a leg up on everyone else when the technology finally gets to a point where blood based tests can detect incredibly small amounts of mutant DNA against a huge background of normal DNA.

    And some food for thought on using inflammation markers - Aspen Biopharma has been trying to using a panel of "inflammation markers" for their appendicitis test for years. This is a setting that would seem ideal for inflammation markers, but even Aspen is getting piss poor results. Inflammation is just way too of a generic marker family.
