Diagnostic tests
Neurological diagnostic tests
INPM performs neurological diagnostic tests in its own offices in Walnut Creek and Vallejo. They include VNG and posturography, TCD bubble study, carotid and transcranial Doppler, autonomic testing, long-term and sleep-deprived EEG, nerve fiber skin biopsy and computer-based cognitive testing. INPM also offers GeneSight® genetic testing to help guide medication choices.
The diagnostic tests are done in our offices and are ordered by your INPM clinician after a referral and evaluation. Each page explains what the test is for, how to prepare, what happens step by step and when to expect results.
