Htlv I Ii Western Blot
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. ...Read more
Yes: Of course the lab would be happy to accept your money for repeat testing - but the question is why a repeat western blot. If the elisa antibody screen is negative you do not need western blot confirmation, and if it is positive but the western blot results suggested biological false-positive results, then if you do not believe these, a PCR for viral nucleic acid is the best answer. ...Read more

Protein assay: Laboratory assay designed to identify a specific protein within a sample (eg serum sample). The biochemical properties of protein enable its passage through a gel matrix across electric current. The specific protein is then identified through detection by antibody. Oddly, there is such a thing as Southern and Northern blots (for DNA and RNA, respectively), but no Eastern blot. ...Read more
High disease area?: The Western Blot is the 2nd (after the ELISA) in a 2-step process. An individual in an area where Lyme disease is common & with high exposure to Lyme-disease carrying tick bite who has been bitten by an engorged tick is highly likely to have Lyme disease if these tests are positive. Without these risk factors, a positive test could be falsely positive. ...Read moreSee 1 more doctor answer
