What is 5-HYDROXY INDOLE ACETIC ACID?
This blood test measures the level of 5-hydroxyindoleacetic acid (5-HIAA), which is a breakdown product of serotonin. Serotonin is a chemical produced by certain cells in your body, including those in the gut.
Why is this test important?
Elevated levels of 5-HIAA in the blood can indicate the presence of carcinoid tumors, which are rare, slow-growing cancers that produce excess serotonin. This test is crucial for diagnosing and monitoring these tumors, especially when symptoms like flushing or diarrhea are present.
How to Prepare
Specific dietary restrictions (e.g., avoiding bananas, avocados, pineapples, tomatoes, nuts, and certain medications) are usually required for several days before the test. Consult your doctor for detailed instructions.
