| Concept | Acoustic reflex test result |
| Description | Record of measurements from an acoustic reflex test, and their clinical interpretation. |
| Use | Use to record measurements from a single acoustic reflext test, for diagnostic or screening purposes. Ipsilateral testing, contralateral testing or both, can be recorded per test ear. Use to record the interpretation of all measurements for each single ear test configuration, and an overall interpretation (or audiological diagnosis). Acoustic reflexes measure the eardrum movement generated by the stapedius and tensor tympani reflex in response to intense sound. The acoustic reflex threshold can be helpful in checking for particular types of hearing loss in situations where patient reliability is questionable. Acoustic reflex testing can also be done as part of a battery of tests to investigate central nervous system pathology, although this usage is now uncommon. |
| Purpose | To record measurements from an acoustic reflex test, and their interpretation by a clnician. |

| Intensity | Intensity: The loudness of the screening stimulus. Property: Loudness Units: dB |
| Frequency | Frequency: The frequency of the test signal. |
| Test Signal Type | Test Signal Type: The type of stimulation used to elicit a reflex. For example: Pure Tone |
| Immittance Machine | Immittance Machine: Details of immittance machine used to conduct the test. Include: openEHR-EHR-CLUSTER.device.v1 and specialisations |
| Normal Range Definition | Normal Range Definition: Definition of the 'Normal Range' value specified within the Intensity data element used for Clinical Interpretation of the Diagnostic Test. |
| Comment | Comment: Additional narrative about the method of testing not captured in other fields. |
| Extension | Extension: Additional information required to capture local content or to align with other reference models/formalisms. For example: local information requirements or additional metadata to align with FHIR or CIMI equivalents. Include: All not explicitly excluded archetypes |

| Confounding Factors | Confounding Factors: Description of incidental factors that may be contributing to the test result. For example: The infant was crying at the time of testing. |
| data | |
| Test Result Name | Test Result Name: Identification of the acoustic reflex test performed. The name of the test identifies the of type of stimulus used - either an acoustic or non acoustic stimulus.
|
| Result Details | Result Details: The test measurements and interpretations which can be recorded per ear, and includes ipsilateral and contralateral testing. |
| Test Ear Configuration | Test Ear Configuration: Identification of the ear to which the stimulus is presented and the ear where the probe is situated.
|
| Diagnostic Test | Diagnostic Test: Reflex test that measures threshold levelss, reflex latency, reflex amplitude and reflex decay. |
| Result | Result: The result of the test. |
| Test Signal | Test Signal: Identification of the stimulation signal used for the test.
|
| Threshold Level | Threshold Level: The lowest stimulation level at which a reflex could be measured by the probe. Property: Loudness Units: 1.0..110.0 dB Limit decimal places: 0 |
| Reflex Latency | Reflex Latency: Length of time from onset of the stimulation tone to the onset of the middle ear muscle reflex. Property: Time Units:
|
| Reflex Decay | Reflex Decay: Length of time that the reflex amplitude can be sustained. Property: Time Units:
|
| No Diagnostic Result | No Diagnostic Result: No diagnostic test result is available for the test ear configuration. |
| Reason For No Test Result | Reason For No Test Result: Reason why no diagnostic test result is available for the test ear configuration. |
| Clinical Interpretation | Clinical Interpretation: Clinical interpretation of all diagnostic results for the specified test ear configuration. |
| Intensity | Intensity: Clinical interpretation of reflex threshold during diagnostic testing, based on intensity.
|
| Sensation Level | Sensation Level: Clinical interpretation of reflex Threshold Level result based on sensation level. Sensation level is the difference between the intensity of the stimulation tone and the patient's hearing threshold as measured on the audiogram.
|
| Screening Result | Screening Result: Reflex test that identifies the presence or absence of a reflex at a predetermined stimulation level. |
| Result | Result: Result of the test.
|
| No Screening Result | No Screening Result: No screening test result is available for the test ear configuration. |
| Reason For No Test Result | Reason For No Test Result: Reason why no screening test result is available for the test ear configuration. For example: ran out of time. |
| Clinical Interpretation | Clinical Interpretation: Clinical interpretation of the screening test result. |
| Overall Interpretation | Overall Interpretation: Overall clinical interpretation of all of the results. Coding with a terminology is preferred, where possible. |
