New blood test may lead to mass vCJD screening

LARGE-SCALE screening of individuals with asymptomatic variant Creutzfeldt-Jakob disease (vCJD) may soon be possible with the development of a new blood test.

Most cases of vCJD have occurred in the UK, resulting from consumption of food infected with the bovine spongiform encephalopathy (BSE) agent, but infection has also been transmitted by blood transfusions and plasma products.
