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.

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.

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.

Pls get me the right info.

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

NO. read testing guidelines of the tests.

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

[Teak]

3 months is conclusive.

[Teak]

A rapid test is an ELISA a western blot is another test by itself.

[hivtestingindia]

Does ELISA and WB test are also part of rapid test?and how accurate is rapid test if done after 6 weeks or 3 months?

[hivtestingindia]

Thanks for ur all comments.Can you also tell me what happened in rapid hiv test?as this test is known by the name that is rapid test only.What sort of tests are performend in rapid tests?

[Teak]

No not when you test is done at 3 months post exposure.

[hivtestingindia]

and about my other question that is,is that ever happend to get false -ve WB test?and when some one come up with -ve ELISA test then WB test still performen or not?

[Teak]

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

[LIZZIE LOU]

if you have a positive elisa and a negative western blot...it means you are negative!

[hivtestingindia]

sorry what does that mean?

[LIZZIE LOU]

a western blot result TRUMPS all other results.
