Our naturopathic doctors in Vancouver WA utilize both standard laboratory tests and specialized laboratory assessment tools to investigate the causes of their patients’ symptoms. The tests ordered by naturopathic doctors can provide insight into a patient’s cardiovascular, metabolic, immune, digestive, nutritional and endocrine health. Tests requiring a blood draw or urine samples are typically performed at a commercial lab such as Quest Diagnostics but sometimes can be performed in the office. Many specialized and alternative testing can be performed at home by the patient via salivary, stool, blood spot, or urine collection.
