5-Hydroxyindole Acetic Acid (5-HIAA), 24 hr Urine

The following foods and medications should be avoided for three (3) days prior to the collection of urine, and during the collection of the sample:
Foods containing high hydroxyindole concentrations (e.g. aubergines, avocados, bananas, black- and red-currants, kiwi, gooseberries, melons, tomatoes, plums, pineapples and walnuts) as well as Glyceryl Guaiacolate (an ingredient in some cough medicines) can increase urinary 5-HIAA excretion. Pregnancy and sleep deprivation can also result in raised 5-HIAA excretion.
Medications and drugs such as Levodopa, Methyldopa, Monoamine Oxidase Inhibitors, Ethanol, Imipramine, Isoniazid, Reserpine and p-Chlorophenylalanine can reduce 5- HIAA production. Others, such as Acetanilide, Phenacetin, Methocarbamol, Cisplatin, Fluorouracil, Melphalan and Rauwolfia Alkaloids can increase urinary 5-HIAA, as can 5- Hydroxytryptophan, which is used to treat depression and is available over-the-counter.

Provide 24 hour volume and date of collection.
