Canada.com is reporting that there's a new test for human Mad Cow Disease (vCJD) in the pipeline that will allow medical professionals to test a blood sample rather than a brain sample. Currently, the only real way to confirm a diagnosis of vCJD is to do an autopsy and take a brain sample under carefully controlled conditions. Current procedures require the destruction of all medical instruments used in the autopsy, since vCJD prions can survive normal decontamination procedures.
