The fecal elastase test measures the concentration of the elastase-3B enzyme found in fecal matter with an enzyme-linked immunosorbent assay . Results of this test can give a good indication of exocrine pancreatic status, and the test is less invasive and expensive than the current "gold standard", secretin-cholecystokinin test. [9] Levels of ...
The gene that codes for pancreatic elastase 1 is CELA1 (synonym: ELA1) Pancreatic elastase 1 is encoded by a single genetic locus on chromosome 12. Studies of human pancreatic elastase 1 have shown that this serine protease maps to the chromosomal region 12q13 [ 10 ] and it is close to a locus for an autosomal dominant skin disease, Diffuse ...
The latter is a less used test that assesses exocrine function in the pancreas by inserting a tube into the small intestine to collect pancreatic secretions. The fecal elastase test is a less cumbersome test that has replaced the 72-hour fecal fat test; in the fecal elastase test, pancreatic enzyme replacement therapy (enzyme supplementation ...
Exocrine pancreatic insufficiency can be confirmed by also checking a fecal elastase level, with low levels specifying exocrine pancreatic insufficiency. [3] A quantitative fecal fat test can also be done to quantify the fat levels in the stool and confirm the presence of exocrine pancreatic insufficiency. [3]
A fecal pH test may be used to determine lactose intolerance or the presence of an infection. [13] Steatorrhea can be diagnosed using a fecal fat test, which checks for the malabsorption of fat. [14] Faecal elastase levels are becoming the mainstay of pancreatitis diagnosis.
In chronic pancreatitis, the fecal pancreatic elastase-1 (FPE-1) test is a marker of exocrine pancreatic function. Additional tests that may be useful in evaluating chronic pancreatitis include hemoglobin A1C , immunoglobulin G4 , rheumatoid factor , and anti-nuclear antibody .
Humans have six elastase genes which encode the structurally similar proteins elastase 1, 2, 2A, 2B, 3A, and 3B. Unlike other elastases, elastase 3A has little elastolytic activity. Like most of the human elastases, elastase 3A is secreted from the pancreas as a zymogen and, like other serine proteases such as trypsin, chymotrypsin and ...
The four "pancreatic elastases", chymotrypsin, and neutrophil elastase are serine proteases. [3] The "macrophage elastase" is a matrix metallopeptidase . Chymotrypsin is weaker at digesting elastin than the architypical pancreatic elastase.
