Description

Secretory IgA – Gut Immune Function

Secretory IgA is one of the most important immune markers in the gastrointestinal tract. It reflects mucosal immune activity and may help identify whether the gut immune system is underactive, overstimulated, or chronically challenged.

This test can be clinically useful in patients with recurrent infections, chronic digestive symptoms, food reactions, dysbiosis, or suspected immune imbalance within the gut.

What this test evaluates

  • Secretory IgA as a marker of mucosal immune function

Who may benefit

  • Patients with chronic digestive symptoms
  • Individuals with suspected gut immune imbalance
  • Patients with recurrent infections or food-related symptoms
  • Cases of dysbiosis, microbiome disruption, or chronic gut irritation

Sample type

Stool sample collected at home using a dedicated collection kit.

Turnaround time

Approximately 5 to 7 working days after sample arrival at the laboratory.

  • Includes: Secretory IgA level assessment
  • Sample requirement: Stool

Suitable for postal submission.

Preparing for this test

WHL will send detailed collection, storage and return instructions with your test kit or appointment confirmation. Those test-specific instructions take priority.

Sample: Stool

Fasting: An overnight fast is usually not needed. Follow the kit’s food, drink and collection-timing instructions.

Use only the supplied stool containers. Discuss antibiotics, probiotics or bowel treatments with WHL before collection; the required timing depends on the test.

Do not stop prescribed medicines or prescribed supplements without advice from your treating clinician. Tell WHL about high-dose biotin; some tests need a longer pause. A short supplement pause does not remove all effects of long-term use.

If another test in the same order requires fasting, follow the combined instructions. Ask your clinician or WHL before fasting if you have diabetes, use glucose-lowering medicine, are pregnant, or are arranging testing for a child.

When to expect your results

Usually 3–10 days. This estimate starts when suitable samples reach the laboratory, not on the order or collection date. Shipping is additional. WHL will confirm any test-specific exception; a combined panel follows its slowest component.

Read WHL’s general preparation and reporting guidance

Practical preparation tips

If fasting is requested, drink only plain water in your usual amounts. Do not have coffee, tea, juice, milk, energy drinks, sweets or chewing gum. Avoid smoking or vaping that morning. Book an early appointment and eat after collection.

For a planned blood test, avoid alcohol and unusually strenuous exercise for 24 hours, where practical, and sit quietly for about 15 minutes before collection. Tell WHL if you could not follow the preparation instructions.

Do not extend fasting or change prescribed medication on your own. Ask your clinician first if you have diabetes, need medicine with food, are pregnant, or are arranging testing for a child. WHL’s full test-specific instructions take priority.
