Several blood tests may be ordered when evaluating vertigo to help identify underlying causes. There isn't one single "vertigo blood test."
While there is no specific blood test solely for vertigo, routine blood tests are often performed to help determine potential underlying causes of the dizziness and balance issues associated with vertigo. These tests can help identify conditions that may contribute to vertigo symptoms.
Here are some common blood tests ordered when evaluating vertigo:
-
Complete Blood Count (CBC): Checks for anemia and infection, both of which can cause dizziness.
-
Blood Glucose: Rules out hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), both of which can lead to dizziness and vertigo.
-
Electrolyte Panel: Evaluates the levels of electrolytes like sodium, potassium, and calcium. Imbalances can contribute to dizziness.
-
Thyroid Function Tests: Assesses thyroid hormone levels (TSH, T4, T3) to identify thyroid disorders, which can sometimes cause vertigo.
In summary, instead of a single, specific "vertigo blood test," a panel of blood tests evaluating blood sugar, blood counts, electrolytes, and thyroid function is typically used to investigate potential underlying causes of vertigo.
