Faecal elastase

Faecal elastase

The faecal elastase test is a non-invasive diagnostic tool designed to evaluate pancreatic exocrine function by measuring elastase enzyme levels in stool samples. Elastase, produced by the pancreas, is crucial for digesting proteins in the small intestine. This test is primarily used to diagnose and monitor exocrine pancreatic insufficiency (EPI), a condition marked by insufficient enzyme production leading to nutrient malabsorption and symptoms like steatorrhea, weight loss, and abdominal discomfort. It is also useful in assessing pancreatic function in conditions such as chronic pancreatitis, cystic fibrosis, and pancreatic cancer. The test involves collecting a fresh stool sample, which is analyzed using techniques like ELISA to determine elastase concentration. Results are categorized into normal, moderate, or severe pancreatic insufficiency based on elastase levels. The faecal elastase test is convenient, can be performed at home, and provides a reliable assessment of pancreatic health, aiding in effective diagnosis and management of related conditions.

Purpose of the test

The faecal elastase test is a non-invasive diagnostic tool used to assess pancreatic exocrine function by measuring elastase levels in stool. It is crucial for diagnosing and monitoring exocrine pancreatic insufficiency (EPI), which can lead to nutrient malabsorption and symptoms like steatorrhea and weight loss. The test is also useful in conditions such as chronic pancreatitis and cystic fibrosis. Key points include:

- Normal Level: >200 µg/g indicates a healthy pancreas.
- Moderate Insufficiency: 100-200 µg/g.
- Severe Insufficiency: <100 µg/g.

This test is convenient, with results typically available in 4-10 days.

Who Should Get Tested

The faecal elastase test is essential for evaluating pancreatic function. It measures elastase levels in stool, indicating enzyme production by the pancreas. This test is crucial for diagnosing and monitoring exocrine pancreatic insufficiency (EPI), which can cause nutrient malabsorption and symptoms like weight loss and abdominal discomfort. Key applications include:

- Diagnosing EPI in patients with unexplained gastrointestinal symptoms.
- Monitoring pancreatic function in conditions like cystic fibrosis and chronic pancreatitis.
- Screening for pancreatic damage or dysfunction.

The test is non-invasive, convenient, and provides clear results, aiding in effective diagnosis and management.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results is crucial for interpreting the faecal elastase test, which assesses pancreatic function. Here's a quick guide:

- Normal Levels: Elastase >200 µg/g indicates a healthy pancreas.
- Moderate Insufficiency: Elastase 100-200 µg/g suggests moderate pancreatic insufficiency.
- Severe Insufficiency: Elastase <100 µg/g indicates severe insufficiency.

While normal results suggest optimal function, they don't rule out pancreatic issues entirely. Further testing may be needed for a comprehensive diagnosis. Always consult with a healthcare provider for accurate interpretation and next steps.
