Diagnosis of ciguatera poisoning is primarily clinical, based on the patient's history of recent fish consumption and the characteristic symptoms. There are no specific laboratory tests available for routine clinical use to detect ciguatoxins in humans. However, research laboratories may use methods like mass spectrometry to detect ciguatoxins in fish samples. Clinicians often rely on the exclusion of other potential causes for the symptoms and the recognition of the unique symptom profile associated with ciguatera.
