Serotonin
Clinical relevance
Serotonin (5-hydroxytryptamine) is a biogenic amine. In humans, serotonin is involved in a large number of physiological processes, e.g. it acts as a tissue hormone and neurotransmitter in the central nervous system, the enteric nervous system and the cardiovascular system. A large amount of serotonin is found in the chromaffin cells of the gastrointestinal tract where it is part of the gastrointestinal hormone system. When released into the capillary blood, serotonin is almost absorbed by the thrombocytes.
A number of diseases are associated with pathological changes in the serotonin metabolism. For the routine, the diagnosis of carcinoid tumours together with the analysis of 5-hydroxyindoleacetic acid (5-HIAA) is very important.
This assay allows determination of serotonin in urine with HPLC (high performance liquid chromatography) with electrochemical detection.
It is intended as a monitoring test for patients with suspected serotonin-secreting tumours.
Product advantages
• Easy sample preparation
• Simple pH adjustment with pH indicator
• Short run time
Assay characteristics
The chromatographic determination requires an isocratic HPLC system with electrochemical detection. Calibrator and quality controls are available separately – they are produced from human matrices to prevent matrix-associated measurement variabilities.
Alternatively, Chromsystems offers an assay for determining serotonin in serum/plasma and whole blood (order no. 3030).
Detailed performance evaluation data for this assay can be found in the appendices of the instruction manual.
