What’s wrong with my digestive system?

Blood tests can measure levels of pancreatic enzymes that help you digest food, detect bowel syndrome conditions and identify nutritional deficiencies. Stool testing can diagnose digestive problems like parasitic infections, H. pylori, even cancer. Breath and saliva testing can show whether digestive bacteria have overgrown your small intestine. Digestive health concerns? These tests can help.

What do digestive lab tests look for?

  • Get to the bottom of digestive problems like diarrhea
  • Find out if you're suffering from enzyme deficiency
  • Test for metabolism, lactose intolerance and IBS
  • Determine your risk for Crohn's or Celiac disease
  • Uncover dangerous bacterial or parasitic infections
  • Choose from saliva, breath, blood or fecal swab tests

Digestive Health Laboratory Tests

Some of the lab tests for digestive issues are blood tests—but not all of them. There are fecal tests, urine tests and even minimally invasive saliva cheek swabs and breath testing. Check out the tests below, and figure out what’s bugging your gut!

Assesses small intestinal bacterial overgrowth (SIBO)

  • Save

This home breath kit measures gases that can indicate the presence of small intestinal bacterial overgrowth (SIBO). The lactulose breath test is one of two tests that measure hydrogen and/or methane gases.

NEW comprehensive stool test measure gastrointestinal health

  • Save

The GI360™ Profile provides in-depth insight into microbiome diversity, dysbiosis, and markers of intestinal health, with easy at-a-glance visual interpretation of results.

Combines multiple GI tests to give you the big picture

  • Save

Gastrointestinal complaints are common, but many of us are unsure of the causes. This fecal panel assesses your gut health in the areas of digestion/absorption, microbiome, inflammation, immune response, intestinal health markers, pathogenic bacteria, yeast, parasites and more.

Is this bacteria the cause of your gastritis?

  • Save

Helicobacter pylori (H. pylori) is a bacterium that can inhabit various areas of the stomach and small intestine. This test measures for IgG antibodies to H. pylori, which are strongly associated with chronic gastritis and peptic ulcer disease.

Measures lipase, a pancreatic enzyme that breaks down fats

  • Save

If you're concerned about pancreatitis because of your gastrointestinal symptoms, you or your doctor may want to assess your levels of lipase, a digestive enzyme made by the pancreas that helps break down dietary fat.

Measures amylase, a pancreatic enzyme that converts starch to sugars

  • Save

If you're concerned about pancreatitis because you've been having gastrointestinal symptoms, you or your doctor may want to check your levels of amylase, a digestive enzyme made by the pancreas that helps breaks down starchy foods.

  • Save

Celiac disease is an immune-mediated reaction to gluten, resulting in inflammation and other medical symptoms. This panel includes tests for deamidated gliadin IgA, tissue transglutaminase IgA and serum IgA level.

This blood test is used to detect systemic candidiasis (yeast)

  • Save

Assesses genetic risk of celiac disease

  • Save

This simple cheek swab test determines the presence of genetic markers of susceptibility to celiac disease, an immune disorder that results in inflammation following the consumption of foods that contain gluten.
