ANS:

  • Serological tests are the most sensitive and specific tests; includes Immunoblast test, arcs test, ELISA and indirect hemagglutination tests.
  • “The immunoblast test, where available, is the test of choice.” - CMDT, 2005, p 1463.
  • Casoni’s test - Intradennal injection of 0.2 ml of fresh sterile hydatid fluid produces a wheal of 5 cm in diameter within half an hour in pts with hydatid disease. It has been abandoned because of poor specificity.
