Diagnosis of serotonin toxicity is primarily clinical and based on the patient's history and presenting symptoms. There are no specific laboratory tests for serotonin syndrome, but confirming the use of serotonergic medications and ruling out other conditions is crucial. The Hunter Criteria is often used to aid in diagnosis. This involves evaluating symptoms such as spontaneous clonus, inducible clonus, and ocular clonus, among others.
