Gastrointestinal Testing

Lab testing for digestive health

These tests check what’s happening in your digestive system when you have symptoms like bloating, gas, diarrhea, or stomach pain. Stool tests look at gut bacteria, parasites, inflammation, and digestion. You’ll also find breath tests for SIBO, leaky gut tests, and urine tests that measure byproducts made by gut bacteria. Most can be done at home.

What digestive tests can check for

• Gut bacteria, yeast, and parasites
• Inflammation and how well you digest food
• Bacterial overgrowth (SIBO), using a breath test
• Leaky gut
• Byproducts of gut bacteria, measured in urine
