  • direct correlation of fecal pancreatic Elastase concentration and pancreatic function
  • no age-dependency of the fecal pancreatic elastase secretion from
    infancy (first year) on
  • the fecal pancreatic elastase molecule is stable for at least 6 days at refrigeration and for at least 3 days at room temperature
  • polyclonal antibodies raised against synthetized specific sequences of the human pancreatic Elastase
  • high sensitivity and specificity
  • minimum of strain for patients due to non-invasive diagnosis
  • FDA-registered

The Bioserv Elastase ELISA for the detection of fecal pancreatic Elastase allows a highly sensitive and specific determination of fecal pancreatic Elastase, enabling the clinician to establish a prompt and reliable diagnosis of suspected cases of pancreatic insufficiency.

Principle of the test

Sandwich-ELISA with polyclonal antibodies directed against defined sequences of human pancreatic elastase.

Sample material:

  • Stool

Medical indications for the application of the test

Exocrine pancreatic insufficiency, caused by

  • Chronic pancreatitis
    is a progressing disease causing the original and functional pancreatic parenchyma to degenerate in a gradual sclerotic process. Characteristic features are its symptoms (abdominal pain, steatorrhea, loss of weight), typical morphological changes of the pancreas (calcification, a dilated and irregularly demarcated Ductus pancreaticus) as well as a continuous loss of the exocrine and endocrine function (maldigestion, Diabetes mellitus). Clinical prevalence chronic pancreatitis is 6 to 8 cases per 100,000 inhabitants each year. 

  • Hereditary pancreatitis
    is associated with mutations in the genes coding for trypsinogen and a proteinase inhibitor. The patients show a high incidence for pancreatic cancer.

  • Autoimmunologically caused pancreatitis
    clinically manifest pancreatitis without fibrosis and calcifications. Mainly destruction of the pancreatic ducts.

  • Pancreatic cancer
    mostly adenocarcinoma of the head of the pancreas, leading to an obstructive pancreatitis.

  • Cystic fibrosis
    caused by mutations of the gene coding for the protein CFTR (cystic fibrosis transmembrane conductance regulator). The incidence rate is dependent on the ethnic group:

    • Afrika: 1/17.000 births
    • Asia: 1/100.000 births
    • Europe, North America: 1/1.600 - 1/2500 births

    The most common mutation is the in-frame deletion ΔF 508, entailing the loss of a phenylalanine at position 508. 900 more mutations have been described. Only heterozygous carriers of these mutations manifest the disease. The clinical picture is determined by metabolic disorders, obstructive disorders (e.g., pancreatic insufficiency) and chronic infections of the respiratory tract. The disease can be symptomatically treated by enzyme substitution, antibiosis and training of the respiratory musculature.

  • Cholelithiasis (Gallstones)
    may cause an obstructive pancreatitis

  • Diabetes mellitus
    very probably correlates with an enhanced risk for an exocrine pancreatic insufficiency for both type 1 (IDDM = insulin dependent diabetes mellitus=juvenile diabetes mellitus) and for type 2 (NIDDM=non insulin dependent diabetes mellitus mostly of adults).

  • Autoimmunopathies and connectivitides
    can be accompanied by exocrine pancreatic insufficiency. Examples are Wegener's Granulomatosis, sclerodermia and others.

  • Chronic inflammatory bowel diseases
    like, e.g., Morbus Crohn, may cause an exocrine pancreatic insufficiency.

  • Pancreatic resection
    may, depending on the extent of the resection, lead to an exocrine pancreatic insufficiency. The organ reserve of the exocrine pancreas is about 90%, so there is much room for compensation.

  • Shwachman-Diamond-syndrome
    is a very rare autosomal recessive hereditary disease characterized by exocrine pancreatic insufficiency in combination with neutropenia, thrombocytopenia, anemia and, in about half of the cases, metaphysary dysostoses leading to stunted growth.
