A Method For Quantitative Extraction of Urinary 5-Hydroxyindoleacetic Acid
Abstract A method for the quantitative assay of urinary 5-hydroxyindoleacetic acid (5 HIAA) is presented. The limits of accuracy and precision obtained reflect good recovery and reproducibility. The relatively high recovery is largely due to maintaining a low distribution coefficient of 5-HIAA during purification of the aqueous extract ...

Specific Photometric Determination of 5-Hydroxyindoleacetic Acid in Urine [PDF]
Abstract Udenfriend‘s nitrosonaphthol test for 5-hydroxyindoleacetic acid (5-HIAA) is subject to interference by urinary phenolic acids and drug metabolites. Studies in our laboratory have shown that the specificity and sensitivity of the nitrosonaphthol reaction with 5-hydroxyindoles can be greatly enhanced by the addition of 2 ...
