Supporting, in conjunction with other tests, a diagnosis of Creutzfeldt-Jakob disease in patients with rapidly progressive dementia when other neurodegenerative conditions have been excluded.

1. Obtain aliquot from second collection vial.
2. Immediately place aliquot on ice.
3. Specimens that have not been kept refrigerated, or which have been
tested for other analytes previously, may give a false-positive
result.
4. Hemolyzed specimens will give false-positive results. Specimens
should be centrifuged to remove any red cells before shipping. The
test will be canceled if there is any level of hemolysis present.

Note:
1. Specimens that have not been refrigerated, or which have
been tested for other analytes previously, may give a
false-positive result.
2. Separate specimens should be submitted when multiple tests are
ordered. This will reduce the risk of test cancellation due to
stability problems.
