Cancerous (malignant) tumors in the small intestine are very uncommon, occurring in about 9,000 people in the United States each year. Adenocarcinoma is the most common type of cancer of the small intestine. Adenocarcinomas develop in the glandular cells of the lining of the small intestine. People with Crohn disease of the small intestine are more likely than others to develop adenocarcinoma.
Test Overview. A brain natriuretic peptide (BNP) test measures the amount of the BNP hormone in your blood. BNP is made by your heart and shows how well your heart is working. Normally, only a low amount of BNP is found in your blood.
MEASURING BNP Blood samples were kept at room temperature and analyzed within 4 hours of being taken from the patient. Each blood sample was analyzed 3 times using the Triage BNP test kit. The test kit is a disposable device. You add 250 ml of blood to it and the kit does the rest. See this article for more on how it works.
