Diese Patienteninformation beschreibt den qualitativen Test der Disaccharid-verdauenden Enzymaktivität im Stuhl (Qualitative) zur Diagnose von Verdauungsproblemen.

Why This Test Might Be Ordered

Your doctor may recommend this test if you have symptoms like chronic diarrhea, bloating, or gas after eating certain foods (e.g., dairy or sugary items). It helps identify if digestive enzymes are insufficient, which can cause trouble absorbing nutrients.

What to Expect Before the Test

No special preparation is needed. Bring any medications you’re currently taking, as some may affect results. Avoid giving your child dairy products (like milk) for 24 hours before testing if instructed by your doctor.

How the Test Works

A small sample of your stool is collected and tested for enzyme activity. The test looks for signs of normal digestion by measuring how well enzymes break down specific carbohydrates in the stool.

Possible Results and Next Steps

If results are normal, your digestive enzymes likely work as expected. If abnormal, further testing (like genetic evaluation or a gluten challenge) may be needed to diagnose conditions like celiac disease or lactose intolerance.
