Faecal Pancreatic Elastase

BÜHLMANN fPELA Assay For Faecal Pancreatic Elastase

  • Utlilises the same CALEX extraction device as the fCAL turbo assay
  • Random access testing on standard clinical chemistry analysers
  • Comparable results to the current ELISA based methods

Pancreatic Insufficiency

Pancreatic insufficiency is the reduction of production or transportation of the digestive enzymes, which results in the inability to properly digest a meal (fats, proteins and carbohydrates). The insufficiency is not absolute, it is variable, which then has a graded impact on digestion and hence symptoms. Patients can suffer from a variety of gastric symptoms, ranging in severity, but including abdominal pain, weight loss, diarrhoea, smelly loose stools, flatulence, loss of appetite and fatigue. All of these can be confused with symptoms of a variety of other gastric complaints. Hence, performing a simple stool test to determine the level of elastase (a pancreatic enzyme), helps with the diagnosis of this condition. Clinicians then just need to determine the cause…

Pancreatic insufficiency really is just another symptom but the cause is almost always pathogenic, resulting from conditions such as chronic pancreatitis, cystic fibrosis, diabetes mellitus, Crohn’s disease, pancreatic cancer plus a variety of other things including lifestyle choices and aging.

Testing Pancreatic Elastase

The new BÜHLMANN fPELA assay utilises the same CALEX extraction device as the fCAL turbo assay, so it is possible to run both tests from a single extract.

The fPELA assay is random access and runs on standard clinical chemistry analysers (Roche, Abbott, Beckman, Siemens etc) although there is also a stand-alone solution as well. The assay is turbidimetric, with a dynamic range of 10 – 5000μg/g. Time to first result is 10 minutes with further results following every few seconds thereafter, making it one of the fastest faecal elastase assays available.

Data from historic NEQAS samples shows the new BÜHLMANN fPELA gives comparable results to the current ELISA based methods:


Pancreatic insufficiency is a consequence of several chronic conditions, and so the testing of faecal pancreatic elastase is in the recommendations for many patient pathways including:

  • BSG guidelines for screening of patients presenting with chronic diarrhoea or malabsorption after the initial infective, cancer and IBS/IBD routes have been investigated.
  • In patients with chronic pancreatitis NICE recommends that patients are monitored for insufficiency every 6 months if they are under 16 years of age otherwise every 12 months.
  • Studies have shown that 63% of newborn infants with cystic fibrosis have pancreatic insufficiency and a further 30% will develop the condition within 36 weeks. Overall 85% of cystic fibrosis patients will have pancreatic insufficiency requiring long term PERT treatment.
    In patients with Cystic Fibrosis NICE recommends ‘testing for exocrine insufficiency using a non-invasive technique such as stool elastase estimation. If the test is normal, repeat it if symptoms or signs suggesting malabsorption occur’.
