title: An improved specific and sensitive radioenzymatic method for determination of serotonin concentrations in biological fluids (radioenzymatic serotonin method).
abstract: Existing radioenzymatic assays for determining the concentration of serotonin in biological fluids have been further modified resulting in increased sensitivity and a lowered detection limit (0.017 pmol). The assay has been used for determinations in platelet-poor plasma (3.3-20.5 nmol/l) and cerebrospinal fluid (0.15-20 nmol/l) from man.
