Anonymous identifier only. Alphanumeric, hyphen, and underscore only. Max 50 characters. Appears in FHIR bundle. If left blank, defaults to UNKNOWN.
The date this ERG was actually recorded — not today’s date, unless the recording was made today. Must not be a future date.
Baker et al. (2025) three-stratum adult framework (18–80 years). This API is designed for adult patients only. Do not use for patients under 18.
Gold Foil and DTL produce Z-score traffic light classification. Contact Lens and Skin return raw feature values with UNAVAILABLE classification — no validated normative dataset exists for these electrode types within this framework (Baker 2025).
ms
ISCEV 2022 minimum is 20 ms. Used to extract baseline noise RMS for SNR calculation.
ms
Flash durations ≥ 5 ms trigger midpoint correction for implicit time measurements (ISCEV 2022).
