“…The present study has shown a sensitivity of 80% for the test. In other works the sensitivities for the ELISA test varied from 62 to 87.5%, depending on the profile of the sample evaluated 13,15,16,17,18,19,20 . Studies that specifically evaluated the sensitivity of the ELISA test in samples of NCC patients in ventricular and cisternal topographies reported values from 93 to 100% 12,15 .…”
