The result of a Western Blot is the conclusive test. If you test negative on a Western Blot. You're negative.

If an elisa test reports negative and western blot too confirms negative within 4 weeks of possible transmission, can it be confirmed negative ?

NO. read testing guidelines of the tests.

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

The info. you receive here from Teak, LIZZIE LOU, myself, and many others is highly accurate and dependable. I refer you to "TESTING GUIDELINES FOR HIV TESTS" as Teak had already suggested.

Hello

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.

Thanks.
