TheNardi test, also known as themorphine-neostigmine provocation test is a test for dysfunction of thesphincter of Oddi, a valve which divides thebiliary tract from theduodenum. Two medications,morphine andneostigmine, are given to people withsymptoms concerning for sphincter dysfunction, including sharp right-sidedabdominal pain. If the pain is reproduced by the medications, then dysfunction is more likely. The test poorly predicts dysfunction, however, and is rarely used today. The Nardi test was named forGeorge Nardi, who first described the procedure in 1966.
