What is the western blot test used for?
A doctor has provided 1 answer
Diagnostic test: The western blot is a test that identifies proteins from an infectious agent. Probably the best example is the HIV western blot, which is used to confirm a diagnosis of HIV infection in people with positive screening tests (elisa or eia). The screening test can be falsely positive, but in those cases the western blot will be negative.
