Overview
The Fecal Elastase test measures the level of elastase, an enzyme produced by the pancreas, in stool samples.
This test is primarily used to assess pancreatic exocrine function and diagnose conditions such as exocrine pancreatic insufficiency (EPI), which can lead to malabsorption and other gastrointestinal symptoms.
Indications for Testing
The Fecal Elastase test is indicated for:
- Symptoms of Pancreatic Insufficiency: Patients presenting with unexplained diarrhea, weight loss, abdominal pain, steatorrhea (fatty stools), and malnutrition.
- Monitoring Conditions: Useful for monitoring pancreatic function in patients with chronic pancreatitis, cystic fibrosis, or after pancreatic surgery.
- Evaluating Digestive Disorders: Helps in diagnosing the cause of malabsorption and gastrointestinal complaints.
Test Methodology
- Specimen Type: A stool sample is required, typically collected in a clean, dry container.
- Collection Instructions:
- Collect a fresh stool sample (approximately 5 grams).
- No preservatives should be added.
- If not sent immediately, the specimen can be refrigerated or frozen to preserve enzyme activity.
Reference Values
- Normal Range:500 µg elastase/g feces indicates normal pancreatic function
- Moderate to Mild Exocrine Pancreatic Insufficiency:
- 100 – 200 µg elastase/g feces.
- Severe Exocrine Pancreatic Insufficiency:
- <100 µg elastase/g feces.
Turnaround Time
Results for the Fecal Elastase test are typically available within 3 to 5 days, depending on laboratory processing times.
Interpretation of Results
- Normal Results: Suggest adequate pancreatic function and enzyme production.
- Low Results: Indicate potential pancreatic insufficiency, warranting further investigation or management strategies.
