Blood Test for Bloating

May 6, 2026

Blood Test for Bloating

A blood test for bloating investigates the medical conditions that cause persistent abdominal discomfort—including coeliac disease (affecting 1 in 100 people, most undiagnosed), thyroid dysfunction, food intolerances, small intestinal bacterial overgrowth (SIBO) markers, and inflammatory conditions—because chronic bloating isn't normal and often has an identifiable, treatable cause.

At Blood Test London, our bloating investigation panel costs from £295 with results in 2-3 days. A doctor always reviews every result.

Find Out Why You're Bloated

Causes of Chronic Bloating

Digestive Conditions

  • Coeliac disease (often undiagnosed)

  • Inflammatory bowel disease (IBD)

  • Small intestinal bacterial overgrowth (SIBO)

  • Food intolerances

Hormonal/Metabolic

  • Thyroid dysfunction (hypothyroidism)

  • Perimenopause/menopause

  • PCOS

Other Causes

  • IBS (diagnosis of exclusion)

  • Ovarian issues (women—persistent bloating)

  • Dietary factors

What Our Bloating Panel Tests

Priority Tests

  • Coeliac antibodies (tTG-IgA) — Rules out/diagnoses coeliac

  • Full blood count — Anaemia suggests malabsorption

  • Thyroid function — Hypothyroid causes bloating

Supporting Tests

  • Iron and ferritin (low = malabsorption)

  • Vitamin B12 and folate

  • Vitamin D

  • CRP (inflammation)

  • Liver function

Optional Add-Ons

  • Food intolerance panel

  • CA-125 (women with persistent bloating)

Important: Coeliac Testing

You MUST be eating gluten for coeliac antibodies to work.

  • Eat gluten daily for 6+ weeks before testing

  • If already gluten-free, discuss with doctor first
