When tested for hiv, how should a strongly positive ELISA test (index above 7) and a negative western blot be interpreted?   What additional testing is required?

Likely negative: This is probably a negative test. If the results haven't changed in a month, then you're definitely not infected. If you don't want to wait that long, you could get a viral load test. An undetectable viral load would be highly reassuring, but i'd still repeat the serology. ...Read more

Are allergic tests for cats definitive? Will the test be done for all for major allergens known in cats?

Depends: There are two materials used for cat allergy testing - hair & skin. Both contain the major cat allergen. Cat skin contains other allergens - especially cat Albumin - not present in cat hair - that sometimes cause allergic symptoms.

Tested positive on the ELISA test for hsv2, a month later tested negative via western blot 2 years after possible exposure . Which test to believe?

Tested positive on the ELISA test for hsv2, a month later tested negative via western blot 2 years after possible exposure . Which test to believe?

Both!: ELISA is very sensitive and sometimes gives a false positive. Interfering substances in serum can make the test look positive. On the other hand, Western Blot is very specific. It does not light up unless you really have antibodies to HSV. So, both tests were "right" , but the Western blot indicates that you do not have the antibody to HSV and have not been exposed. ...Read more
