Clinical Information (ข้อมูลทางคลินิก):
Vanillylmandelic acic (VMA) and Homovanillic acid (HVA) are degradation product of adernaline and norepirnephrine, respectively. 5-Hydroxyindoleacetic acid (5-HIAA) are degradation product of serotonin. They play a key role in the transmittion of impulses in the nervous system.
 
Reference Value (ค่าอ้างอิง):
1.Vanillylmandelic Acid(VMA)= 1.60-7.30 mg/24h
2.Homovanillice Acid (HVA)=1.82-6.92 mg/24h 
3.5-Hydroxyindoleacetic Acid (5-HIAA)=2.00-8.00 mg/24h
 
Interpretation (การแปลผล):
High level of VMA and HVA was found in neuroendocrine tumors including neuroblastomas, pheochromocytoma and paraglanglioma. High level of 5-HIAA was found in serotonin producing tumor (carcinoids).
