title: Evaluation of specific immunoglobulin E by enzyme-linked immunosorbent assay in hydatid disease.
abstract: The diagnostic significance of elevated hydatid-specific immunoglobulin E (IgE) as measured by enzyme-linked immunosorbent assay (ELISA) was evaluated against hydatid-specific IgG ELISA and Casoni's intradermal test in surgically proven cases of hydatidosis. A specific IgE ELISA did not correlate with IgG ELISA or Casoni's intradermal test, although its recorded sensitivity was 87%. The specific IgE ELISA was at the same time false-positive in 57.14% of the cases because of its cross-reactions with cases of ascariasis and taeniasis, unlike Casoni's intradermal test and specific IgG ELISA. It is suggested that, in a helminth-infested population, the determination of specific IgE levels is not better than Casoni's intradermal or specific IgG ELISA tests.
