谱析（上海）生物科技有限公司提供——VMA, HVA and 5-HIAA in Urine 质谱诊断方案
 
一、说明
Vanillylmandelic acid (VMA) and homovanillic acid (HVA) are end-products of the catecholamine metabolism. The determination of VMA and HVA in urine serves as a screening test for neuroblastoma, one of the most common solid tumors in early childhood. 5-hydroxyindoleacetic acid (5-HIAA) is a metabolite of serotonin and is used for the diagnosis of carcinoid tumors. The RECIPE ClinRepe@  Complete Kit allows a reliable determination of VMA, HVA and 5-HIAA in only 15 min time for analysis. Also available: Complete kits for automated sample preparation.
