| pubmed-article:6155229 | pubmed:abstractText | After extraction with two organic solvent mixtures, urinary 5-hydroxy-3-indoleacetic acid can be assayed by "high-performance" liquid chromatography on a reversed-phase column, with electrochemical detection. Compared to the nitrosonaphthol method (J. Biol. Chem. 216: 499, 1955), this method is more specific for detection of patients with carcinoid tumors. | lld:pubmed |
