WebMethod: The aim of this study was to compare serum CgA measurement to both serum and 24 h urine 5-HIAA measurement. We measured serum CgA, 24 h urine 5-HIAA excretion and serum 5-HIAA in paired samples from 20 patients with known 5-HIAA secreting neuroendocrine tumours. Patients receiving PPI therapy were excluded from the study.
