Get the Answers Your Gut Has Been Asking For

If you experience symptoms like bloating, headaches, fatigue, or skin issues after eating foods that contain wheat, barley, or rye, you may have a gluten sensitivity. While some people dismiss these reactions as “normal,” they could be signs of gluten intolerance or even coeliac disease—an autoimmune condition that affects the small intestine.

The Gluten Intolerance Test by GetTested offers a clear, lab-based way to assess your body's response to gluten. This simple at-home blood test detects transglutaminase IgG antibodies, which can indicate a heightened immune reaction to gluten and suggest the presence of gluten sensitivity or coeliac-related markers.

What Is Measured?

This test measures IgG antibodies against tissue transglutaminase (tTG)—a key marker used to detect gluten intolerance and potential coeliac disease. Elevated levels may point to an immune response to gluten proteins in your diet, even if you haven’t been officially diagnosed with coeliac disease.

Common Symptoms of Gluten Intolerance

Gluten-related symptoms can vary widely and often affect multiple systems in the body. Common signs include:

• Digestive discomfort (bloating, diarrhoea, constipation)

• Fatigue and low energy

• Headaches and migraines

• Skin conditions like eczema or rashes

• Joint pain or inflammation

• Mood issues such as anxiety or depression

• Trouble concentrating or “brain fog”

• Difficulty gaining or maintaining weight

• Infertility or menstrual irregularities

Gluten Intolerance vs. Coeliac Disease – What’s the Difference?

While both conditions can produce similar symptoms, coeliac disease is an autoimmune disorder—gluten ingestion triggers the immune system to attack the lining of the small intestine, leading to long-term damage. Gluten intolerance, on the other hand, causes discomfort and inflammation but does not damage the intestine.

That said, both conditions can seriously affect your quality of life and may require gluten-free dietary adjustments to manage symptoms and prevent complications.

Nutrient Deficiencies in Coeliac Disease

Chronic intestinal inflammation in coeliac disease can interfere with nutrient absorption. This may lead to:

Iron deficiency, contributing to anaemia

Calcium and vitamin D deficiency, increasing risk of osteoporosis

Folate and vitamin B12 deficiency, affecting energy and red blood cell production

Zinc deficiency, impairing immunity and skin health

Vitamin B6 deficiency, essential for metabolism and brain function

Early detection through testing can help address these imbalances and guide appropriate supplementation or dietary changes.

How Is This Different from a Food Intolerance Test?

While the Food Intolerance Test (40, 80, or 240 items) measures IgG4 antibodies, which detect delayed immune responses to various foods, it does not assess for autoimmune reactions.

In contrast, the Gluten Intolerance Test specifically measures IgG antibodies to tissue transglutaminase (tTG)—a clinical marker that may point to coeliac disease or gluten sensitivity.

In short:

Food Intolerance Test = delayed non-autoimmune food reactions

Gluten Intolerance Test = autoimmune marker for gluten reactivity

How the Test Works

1. Sample Collection: A small blood sample is collected at home using a simple finger-prick kit.

2. Lab Analysis: Your sample is analysed in a certified laboratory.

3. Results: Receive your detailed report within 10–15 business days, showing your IgG levels for gluten sensitivity.

For deeper insights, consider pairing this test with:

Leaky Gut Test – to assess gut permeability and inflammation

Allergy & Intolerance Test – to screen for both IgE (allergy) and IgG4 (intolerance) reactions

Empower Your Health with Clarity and Confidence

Living with undiagnosed gluten sensitivity can lead to years of discomfort, confusion, and trial-and-error dieting. The Gluten Intolerance Test by GetTested provides accurate, targeted insight into how your body responds to gluten—so you can make informed decisions about your diet, reduce inflammation, and support long-term gut health.

If you suspect gluten is affecting your well-being, this test is a smart, accessible place to start.
