Fecal chymotrypsin

When the enzymes in the pancreatic juice pass through the intestinal tract, most of them are decomposed into amino acids which are reabsorbed by the small intestine, and only chymotrypsin is less damaged. Fecal chymotrypsin assay can be used as an indicator of pancreatic exocrine function to a certain extent. Clinically, the principle of spectrophotometry is used for determination. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Tips: Tell your doctor about the history of medication before checking. Normal value 1. Normal value > 100 μg/g. 2. 100 to 75 μg/g is suspicious, and less than 75 μg/g is abnormal. Clinical significance Abnormal results: Fecal chymotrypsin assay has certain value for the diagnosis of chronic pancreatitis or cancerous disease, especially for the diagnosis of pancreatic fibrotic cyst disease. The majority of patients are children, which is difficult to accept for duodenal intubation. The chymotrypsin assay basically solves the diagnostic problem. The content of chymase in feces of pancreatic fibrocystic disease was significantly reduced, while that of non-pancreatic steatorrhea was significantly increased. Need to check the object: 1, long-term gastrointestinal discomfort. 2, children. Low results may be diseases: chronic pancreatitis in children, chronic pancreatitis precautions Preparation before inspection: The stools were collected in plastic bags for 72 hours and stored frozen for testing. Note when checking: 1. Tell the doctor about the history of medication. 2, this inspection is mostly for children, so you need to pay more attention when checking. Not suitable for people: Nothing is suitable for the crowd. Inspection process This test uses ultraviolet spectrophotometry. The principle of ultraviolet spectrophotometry: visible light, ultraviolet radiation to certain substances, mainly due to the absorption of radiation by the valence electron level transition in the material molecule, resulting in the visible ultraviolet absorption spectrum of the compound. Based on the selective absorption of light by the substance Establish analytical methods for spectrophotometry or absorption spectroscopy. Not suitable for the crowd Nothing is suitable for the crowd. Adverse reactions and risks This check will not cause complications or harm.
