Test Reliability
6-5
In addition to a high false positive finding, trigger happy patients often show threshold results that
are abnormally high. An example of this phenomenon is shown in
. Any individual point
result of 40 dB or greater indicates a hypersensitive result which can only be due to patient
overreaction or guessing when pressing the patient response button. It is best to note the results
early in the exam and start the test over rather than to allow the test to run to completion and be
completely invalid.
