HE QUANTITATIVE ESTIMATION of urinary 5-hydroxyindoleacetic acid (5-HIAA) has attained clinical importance with increasing interest in indole metabolism. Urinary 5-HIAA levels have largely been determined by the use of an extraction procedure described by Udenfriend et al. (1). The author has found, as have others (2), that this method produces inconsistent results on varying dilutions of a given urine sample and suggests the following extraction procedure to circumvent the source of error.
