  • Page 15: Interpreting Test Results

    Interpreting test results A patient screened by the AccuScreen PRO is either given a PASS or a REFER. If the result is a PASS, no further action is required. If the result is a REFER, it is recommended that you retest the patient. If the patient is given yet another REFER, this patient should be referred for further testing.

  • Page 19: Abr Results

    ABR results PASS A PASS indicates that an auditory brainstem response to a 35 or 45 dB nHL broadband stimulus was detected. This method mainly tests the frequencies from 2000 to 4000 Hz, which carry the most important acoustic information for speech development. A PASS result ensures that a significant hear- ing loss in these frequencies can be ruled out with 99.5% confidence.
