Abstract:
Examination of the serotonin metabolite, 5-hydroxyindoleacetic acid (5-HIAA), in the urine of psychiatry patients has generally not been used because the reliability of urinary 5-HIAA levels has been questioned. Thirty-seven generalized anxiety disordered patients collected two consecutive urines for measurement of 5-HIAA. The correlation of the 5-HIAA collections was r = 0.82, p = 0.0001.
