In our report, the values of whole blood serotonin (5-HT) in 87 apudoma patients (diagnosed by operation and pathology) were summarized. Among them, the levels of urinary 5-hydroxyindole-3-acetic acid (5-HIAA) of 44 patients were also tested. The results showed that both parametres of apudoma patients were higher than those of non-apudoma, post-operative patients of apudoma as well as the normal. The increasing extent of the levels of whole blood 5-HT and urinary 5-HIAA in small intestinal carcinoid was the most obvious one but that of rectum was not. The referable diagnostic values suggested were: 5-HT>130 ng/ml, 5-HIAA>30 mg/ 24 hours.
