Pancreas Health

  • Faecal Elastase

About this test

The Faecal Elastase Test measures elastase, an enzyme released into the gut by the pancreas, in a stool sample. A low level can indicate that the pancreas is not releasing enough digestive enzymes, a condition sometimes described as pancreatic exocrine insufficiency, which can cause chronic diarrhoea, pale or greasy stools and weight loss.

At £63, it costs about 42% less than the £108 median for the 29 similarly sized gut health tests we track, though as a single, narrowly focused marker its Clinical Depth score sits in the lower third of that wider set. There is no direct comparison group of equivalent pancreatic function tests in our data to benchmark it against more precisely.

value for money scores well given how far below the broader gut health median it sits, but Collection Convenience is lower than most of Selph's other stool tests, reflecting a turnaround of 7 to 8 days rather than the 1 to 6 days typical elsewhere in the range.

Who is it for?

This suits you if you have symptoms suggestive of pancreatic enzyme insufficiency, such as chronic diarrhoea, pale or floating stools and weight loss, particularly alongside a risk factor such as chronic pancreatitis, coeliac disease or a history of bariatric surgery. If your symptoms are more general gut discomfort without these specific features, a broader panel such as Selph's Complete Gut Health Test & Symptom Screen may be more useful; speak to your GP about which test fits your symptoms.

How it works

You collect a stool sample at home and post it to the lab; there is no blood-based or clinic alternative for this test. A Selph doctor reviews your faecal elastase result and provides a written report, typically within 7 to 8 days.

Pros & cons

Pros

  • About 42% below the £108 median price for similarly sized gut health tests we track.
  • Simple at-home stool collection with no blood draw required.
  • Comes with a written doctor's report explaining your result.

Cons

  • Turnaround of 7 to 8 days is slower than most of Selph's other stool tests.
  • A single, narrow marker aimed at one specific cause of gut symptoms, not a general gut health check.

Our editorial score

Compare Health Test Score Cheap niche marker, but one of Selph's slowest tests
Editorial confidence: 10.0/10

This single-marker faecal elastase test costs £63, about 42% below the £108 median for the 29 similarly sized gut health tests we track. It is a narrow test, aimed specifically at pancreatic enzyme function rather than gut symptoms generally, which is reflected in a below-average Clinical Depth score for the category. The main drawback is a comparatively slow turnaround of 7 to 8 days.

Score breakdown

  • Clarity and documentation 9.0/10

    The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.

  • Clinical depth 6.4/10

    1 biomarkers, placing it in the 32nd percentile of gut health tests we track.

  • Collection convenience 7.0/10

    A stool sample you take at home, no needle; results in around 8 days, slower than similar tests.

  • Results and follow-up 7.0/10

    Results are reviewed by a doctor; the provider does not describe the report format.

  • Trust signals 10.0/10

    Trustpilot 4.9 from 71,592 reviews; accredited lab (UKAS ISO 15189 partner labs (Inuvi, TDL)); CQC registered; doctor review as standard.

  • Value for money 8.6/10

    £63.00 against a median of £108.00 for the 29 similarly sized gut health tests we track (-42%).
