How Is BPPV (Benign Paroxysmal Positional Vertigo) Diagnosed? Tests, Criteria & Process
BPPV (Benign Paroxysmal Positional Vertigo) diagnosis relies on Full blood count (FBC), Comprehensive metabolic panel (electrolytes, creatinine, LFTs), Urinalysis. Learn the full diagnostic pathway, clinical criteria, differential workup, and what to expect at your evaluation.
Updated March 27, 2026
BPPV (Benign Paroxysmal Positional Vertigo) is diagnosed using Full blood count (FBC), Comprehensive metabolic panel (electrolytes, creatinine, LFTs), Urinalysis and targeted clinical evaluation. BPPV is the most common cause of vertigo, caused by displaced calcium crystals in the inner ear. It causes brief but intense vertigo triggered by head position changes, treatable with repositioning maneuvers.
Clinical Context
The diagnostic process for BPPV (Benign Paroxysmal Positional Vertigo) begins with Thorough history and physical examination followed by basic blood and urine tests; targeted specialist investigation as needed. Key investigations include Full blood count (FBC), Comprehensive metabolic panel (electrolytes, creatinine, LFTs), Urinalysis, Chest X-ray. The gold standard is: Directed investigation based on clinical history and physical examination findings.

Tests, Criteria & Process usually becomes clinically useful only when the symptom pattern is read in context rather than as a single isolated phrase. On real pages, people search this question when they are trying to separate benign explanations from higher-risk causes such as BPPV (Benign Paroxysmal Positional Vertigo). The symptom becomes more meaningful when it appears together with associated symptoms, because that combination changes which diagnoses move higher on the differential and which ones can be deprioritised. That is why this page now reinforces the diagnostic path with direct links to the strongest canonical symptom and condition hubs, so Google and users can see a clearer entity relationship instead of another standalone FAQ fragment.
