Western blot more: specific, ELISA more sensitive. One positive ELISA and one negative Western blot says that you do not have enough antibodies to HSV 2 for confirmation of diagnosis. It may be prudent to repeat the tests in 3-4 months to make sure that negative Western blot was not due to incomplete/early immune response.
