In the review by AC Deacon published in the Annals in 1994 the period
suggested for dietary restriction in preparation for urinary 5-HIAA was 24
hours. In the past we also had suggested that the period for dietary
restrictions should be 3 days before commensing the urine collection - data
published from Australia (I can not put my hand on the reference) showed
that 5-HIAA from dietary sources was rapidly cleared and the period of
dietary restriction could be reduced to 12 hours prior to and during the
collection of 5-HIAA.
