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.
Many of these other tests do have consistent fasting requirements. It is important to be aware of and check the parameters of all tests that are taken simultaneously. Why It Is Used. The B-type natriuretic peptide blood test, also known as the brain natriuretic peptide (BNP) test, is used for detecting congestive heart failure. This test is used to assess how hard the heart is working to keep the blood pumping through the body and to determine if the heart is pumping the blood well enough.
