What this test measures

2

This section shows the biological marker/agent measured by this diagnostic test. Each marker/agent opens its own page with related conditions. Detailed reference ranges are shown separately in the Reference ranges and concentrations section below, so they are not repeated here.

Reference ranges and concentrations

These ranges are pulled from the existing EH diagnostic-test reference range tables. They can vary by laboratory, method, age, sex, sample type and clinical situation.

Biological marker/agent / concentration	Reference range	Unit	Age	Gender	Category / test group
Normal A and B Waves on Retinograph	1 – 10	Present	All	Both	Electrograph Studies / Eye Tests
Normal Oculovestibular Reflex	1 – 10	Present	All	Both	Electrograph Studies / Eye Tests

Tip: scroll sideways on small screens to see all columns. Ranges are educational only and must be interpreted by a qualified clinician.
