Fecal Elastase Test
The Fecal Elastase Test measures how much elastase is present in a stool sample. The body produces the enzyme to aid in the breakdown of the proteins, carbohydrates, and fats. By measuring the amount of elastase in the stool can assist in figuring out how well the pancreas is working. When Fecal Elastase test levels show lower than normal, it is an indicator of pancreatic insufficiency. This is a condition where the pancreas does not produce enough enzymes to properly digest food and absorb nutrients.
Why is Fecal Elastase Test Important?
- Helps diagnose pancreatic dysfunction causing malabsorption.
- Differentiates between pancreatic and non-pancreatic diarrhea.
- Monitors chronic pancreatitis or cystic fibrosis patients.
Benefits of the Fecal Elastase Test
1. Non-invasive & painless
2. High accuracy for PEI detection
3. No dietary restrictions.
How to improve pancreatic elastase levels
Treatment for EPI typically includes pancreatic enzyme replacement therapy (PERT) and lifestyle changes.PERT involves taking supplements that contain pancreatic enzymes at mealtimes. This helps increase levels of pancreatic elastase so the small intestine can digest food properly.
Lifestyle changes and choices that may help improve pancreatic elastase levels include the following:
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 (> 200 μg/g) – Healthy pancreatic function.
- Moderate (100-200 μg/g) – Mild to moderate insufficiency.
- Severe (< 100 μg/g) – Significant pancreatic dysfunction.
Interpretation of Results
- Normal Results: Suggest adequate pancreatic function and enzyme production.
- Low Results: Indicate potential pancreatic insufficiency, warranting further investigation or management strategies.
Turnaround Time
Results for the Fecal Elastase test are typically available within 3 to 5 days, depending on laboratory processing times.
Frequently Asked Questions (FAQs)
What is a fecal elastase test?
It measures elastase-1, a digestive enzyme produced by the pancreas, in stool samples. Low levels may indicate pancreatic exocrine insufficiency (PEI).
Why is this test done?
It helps diagnose PEI, often linked to conditions like chronic pancreatitis, cystic fibrosis, Crohn’s disease, or diabetes-related pancreatic damage.
What symptoms suggest pancreatic insufficiency?
Symptoms include chronic diarrhea, oily stools (steatorrhea), unexplained weight loss, bloating, and nutrient deficiencies.
How do I prepare for the test?
No fasting is required. Avoid laxatives or stool softeners before collection. Inform your doctor if you’re taking pancreatic enzyme supplements.
How is the stool sample collected?
You’ll use a sterile container to collect a small stool sample. Avoid contamination with urine or toilet water.
Can medications affect the results?
Yes, pancreatic enzyme replacement therapy may alter results. Your doctor might advise pausing them temporarily.
What happens if my result is low?
Your doctor may recommend enzyme supplements, dietary changes, or further testing like imaging studies.
Is this test suitable for children?
Yes, especially for conditions like cystic fibrosis or chronic digestive issues.
How long does it take to get results?
Typically, results are available within 2–5 business days.
