Experiencing recurrent infections, digestive problems, or suspected immune deficiency and want to assess your mucosal immunity and immune system function?

The Immunoglobulin A (IgA) test measures antibodies that protect mucous membranes in the respiratory and digestive tracts. Abnormal IgA levels can indicate immune deficiencies, chronic infections, or autoimmune conditions such as coeliac disease.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"

Overview

The Immunoglobulin A (IgA) test measures your body's security guard for all the places where the outside world meets your inside – think of it as checking on the bouncer that protects your mouth, nose, lungs, and digestive system from unwanted invaders. IgA is like your body's first responder, stationed at these entry points to catch harmful bacteria, viruses, and other troublemakers before they can cause infections or slip deeper into your system.

When your IgA levels are too low (which happens to about 1 in 500 people), it's like having a security system with gaps – you might find yourself getting frequent respiratory infections, digestive issues, or seeming to catch every bug that goes around despite feeling otherwise healthy. This test is particularly helpful if you're dealing with recurring sinus infections, ongoing stomach problems, or if you just can't seem to shake off illnesses as easily as others, as it can reveal whether your body's natural defense system needs some support.

Symptoms

Essential for individuals with recurrent infections, suspected immune deficiencies, chronic digestive issues, or anyone needing comprehensive immune system assessment.

Questions

  • Low IgA (selective IgA deficiency) increases susceptibility to mucosal infections, may be associated with autoimmune conditions and allergies, and can affect the accuracy of certain antibody tests.
  • IgA deficiency can be genetic (primary immunodeficiency) or acquired due to medications, infections, autoimmune diseases, or other conditions affecting immune function.
  • Symptoms may include recurrent respiratory infections, chronic diarrhea, increased allergies, autoimmune conditions, and frequent illness, though some people have no symptoms.
  • While there's no cure for primary IgA deficiency, management includes prompt treatment of infections, avoiding live vaccines, and monitoring for associated conditions.
  • Elevated IgA may indicate chronic infection, autoimmune disease, liver disease, or certain cancers, requiring further evaluation to determine the underlying cause.
  • IgA deficiency can cause false-negative results on IgA-based tests like tissue transglutaminase antibodies for celiac disease, requiring alternative testing methods.

How to prepare

No special preparation required. Inform healthcare provider of recent infections, medications affecting immune function, and any immune-related conditions that might affect results.

After the test

Address abnormal IgA levels through comprehensive immune evaluation, appropriate treatments for underlying conditions, immune support strategies, and regular monitoring. Work with immunologists for specialized care.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results show IgA levels compared to normal ranges. Low levels may indicate immune deficiency requiring further evaluation, while elevated levels might suggest immune activation or certain diseases.

Frequently Asked Questions

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

Just your pathology referral form (we email it to you)

Of course. Just maybe don’t bring the friend who faints at the sight of blood.
