What are the "rules" to prepare for a 5-HIAA urine test? Foods you can't eat, etc. And do these also apply to the blood test?


Ginna Deitrick, CRNP, MSN, Nurse Practitioner for Interventional Radiology at Penn Medicine responds.

For 24 hour 5-HIAA we tell patients to avoid the following foods 5 days before completing the test: avocados, pineapples, bananas, kiwi fruit, plums, eggplants, walnuts, hickory nuts, pecans; and the following medications: Tylenol (Acetaminophen). There are a few other medications that may interfere with the results, but your MD/ NP will be able to advise further.
