With todays ultra sensitive modern ELISA tests, what use is the western blot for hiv? A few months ago i received a weakly reactive cmia HIV ag/ab test, a 4th generation HIV combo test, and this was followed by a negative western blot and a negative p24 t

That is, the test appears positive for someone without the disease. The western blot, being time consuming and extra cost, is only used to make sure a positive is really a positive.

Is CMIA AG/AB at 9.5 months of exposure and 9 months ELISA hiv1/2 all negative.. is it enough although my symptoms? red spots, headache white tongue

See your doctor: I read your question, and then your procedures and the times do not agree. The difference between 9 months and 77 days is huge. A negatve HIV test at 6 months would be definative.

I am going to the doctor today to take a ELISA test. What can I expect?

Elisa Testing: In my experience elisa testing is an antibody test for a viral infection. The test itself, if it is a rapid type of test, should tell you if you are infected with that virus.
