Final answer:
The Pancreolauryl test (PLT) is a screening test used to study platelet function. It involves the ingestion of fluorescein dilaurate, which is hydrolyzed by pancreatic cholesterol esterase, releasing fluorescein. The test measures serum concentrations of fluorescein.
Step-by-step explanation:
A screening test commonly used to study platelet function is the Pancreolauryl test (PLT). This test helps in detecting patients with moderate pancreatic insufficiency.
It involves the ingestion of fluorescein dilaurate, which is hydrolyzed by pancreatic cholesterol esterase, releasing fluorescein.
The released fluorescein is absorbed by the gut, conjugated by the liver, and excreted in the urine. Serum concentrations of fluorescein are measured to assess platelet function.
