Is it possible to detect false -ve result in western blot test after performing ELISA test,what is the condition of person who has come with +ve ELISA test but -ve in western blot test.How much accurate are WB test as if ELISA test can have false +ve test then how can some some say that WB test are accurate if come with -ve result.
NO. The only CONCLUSIVE Negative Result is and ANTIBODY ASSAY at 3 MONTHS. Sometimes Drs. will refer to tests as "INDICATIVE" , this means, with a certain result, that the testee is "UNLIKELY" to be HIV infected, however. "INDICATIVE "does NOT = CONCLUSIVE
If you are concerned, get an HIV antibodies test 12 weeks post exposure. Western Blot test should not be used for routine screening. It is a confirmatory test and negative HIV screening tests (rapid tests, lab. based ELISA etc. tests) ouside the window period do not routinely need further confirmation.
