5-HIAA (HYDROXY INDOLE ACETIC ACID)-RANDOM URINE Test Purpose:

The 5-HIAA (Hydroxy Indole Acetic Acid)-Random Urine Test is performed to measure the level of 5-HIAA, a breakdown product of serotonin, in a random urine sample. Primarily, the test is used to help diagnose and monitor carcinoid tumors, particularly those that produce excess serotonin. Additionally, it assists healthcare providers in investigating symptoms such as flushing, persistent diarrhea, wheezing, and abdominal pain that may be associated with carcinoid syndrome. Furthermore, the test may be used to monitor treatment effectiveness and detect disease recurrence in individuals diagnosed with neuroendocrine tumors. Moreover, the results are interpreted alongside imaging studies, blood tests, and clinical findings to provide a comprehensive evaluation.

5-HIAA (HYDROXY INDOLE ACETIC ACID)-RANDOM URINE Test is Recommended for Individuals:

• Individuals with suspected carcinoid tumors.
• People experiencing persistent flushing of the face or neck.
• Individuals with chronic unexplained diarrhea.
• Patients with wheezing or asthma-like symptoms without an obvious cause.
• Individuals with suspected carcinoid syndrome.
• Patients undergoing treatment for neuroendocrine tumors.
• People with unexplained abdominal pain or symptoms suggestive of excess serotonin production.
• Anyone advised by an oncologist or healthcare provider to evaluate serotonin metabolism.

2. Do I need to prepare before the 5-HIAA Random Urine Test?
Yes. Certain foods and medications may affect the results. Therefore, your healthcare provider may advise you to avoid foods such as bananas, tomatoes, avocados, pineapples, walnuts, and certain medicines for a specified period before the test.

3. What does a high 5-HIAA level indicate?
A high 5-HIAA level may indicate carcinoid tumors or carcinoid syndrome caused by excess serotonin production. However, the results should always be interpreted together with your symptoms, imaging studies, and other laboratory tests by a healthcare professional.
