Serotornin Plasma / Urine

Serotonin is a neurotransmitter in the central nervous system. Serotonin deficiencies are connected with disorders such as depression, schizophrenia, and Parkinson’s disease. Serotonin is produced by carcinoid tumors.

In Urine.

Patients with carcinoid tumors usually show increased levels of serotonin in plasma and urine as well as of 5-HIAA in urine. As some tumors show a decreased serotonin turnover (e.g. AADC-deficient tumors), low 5-HIAA levels must be verified by the determination of serotonin. The test kit of RECIPE provides a highly selective sample preparation and guarantees a reliable chromatography.

In Plasma.

The determination of serotonin, together with its metabolite 5-HIAA, is used to confirm or exclude a tumor. The RECIPE test kit allows a quick and sensitive determination of serotonin from platelet-rich plasma, platelet-poor plasma and serum. For the determination from urine an additional test kit is available.
