谱析（上海）生物科技有限公司提供——Serotonin in Urine 质谱诊断方案
 
一、说明
Serotonin is an important neurotransmitter. The main metabolite of serotonin is 5-hydroxyindole acetic acid (5-HIAA) which is excreted with 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 RECIPE test kit provides a highly selective sample preparation and guarantees a reliable chromatography.
