Over time, diagnoses sometimes change when additional evidence or
symptoms appear. Regarding genetic testing for
narcolepsy, positive test results indicate a susceptibility to narcolepsy but do not definatively diagnose narcolepsy. Positive genetic tests results are used to support a clinical diagnosis of narcolepsy.
We recommend that you speak with your doctor regarding your symptoms and test results as well as to discuss the most appropriate course of treatment for your specific situation.
