Western Blot for what? Depends if it's been validated for x condition (the CDC will know).

WB is a well established technique for diagnosis in many disease.

All tests produce false postives, for WBs they's extremely low in incidence, like a fraction of 1%, and they usually do 3+ screens in each test just in case.
