Estrogen analysis may be helpful in establishing time of ovulation and optimal time for conception. Serial samples must be collected over several days to evaluate baseline and peak total estrogen levels.The majority of gastroenteropancreatic neuroendocrine, carcinoid tumors do not produce elevated whole blood or serum serotonin levels. In most cases, 5-hydroxyindoleacetic acid (5-HIAA) and chromogranin A are superior tests for the assessment of carcinoid syndrome.1-4 In rare instances, a deficiency of aromatic amino acids decarboxylase in carcinoid tumor cell limits the conversion of 5-HTP ...The chromogranin A test (CgA) is used in combination with 5-HIAA to help diagnose carcinoid tumors and may also be used to detect other neuroendocrine tumors.
