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.
- Simple and efficient sample preparation
- Fast results due to short analysis times
- Long column life times
This assay allows for reliable HPLC determination of serotonin in urine as part of routine diagnostic laboratory testing. Easy and fast sample preparation leads to exact and reproducible results. The chromatographic determination requires an isocratic HPLC system with electrochemical detection. Calibrator and quality controls are available separately – they are produced from pure 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).
