Final answer:
To test for intact absorption in someone who had removal of the pancreas, several tests can be done including the pancreolauryl test, direct test of exocrine pancreatic function, and secretin-pancreozymin test.
Step-by-step explanation:
To test for intact absorption in someone who had removal of the pancreas, there are several tests that can be done:
- Pancreolauryl test (PLT): This test measures the concentration of fluorescein in the serum, which is absorbed by the gut after the ingestion of fluorescein dilaurate with a standard breakfast. It has the same sensitivity and specificity as urine collection.
- Direct test of exocrine pancreatic function: This test measures the percentage recovery of p-aminobenzoic acid (PABA) in the urine after the ingestion of N-benzoyl-L-tyrosyl-p-aminobenzoic acid (Bz Ty PABA), which is hydrolyzed by chymotrypsin in the small intestine.
- Secretin-pancreozymin test: This test analyzes duodenal contents for various pancreatic enzymes following the injection of secretin and pancreozymin. It provides information about pancreatic function and can help diagnose pancreatic insufficiency.
