What Is an Immunoglobulin IgA Test?
The Immunoglobulin IgA test measures the level of Immunoglobulin A, an antibody protein that plays a key role in protecting the body's mucosal surfaces, such as the lining of the lungs, digestive tract, and sinuses. A doctor may order this test when a patient has frequent infections or when an immune system disorder is suspected. It is also known as the IgA blood test, quantitative IgA, or total IgA. The test uses a small blood sample drawn from a vein.
What Does an Immunoglobulin IgA Test Measure?
The Immunoglobulin IgA test procedure measures the concentration of IgA antibodies in your blood. IgA makes up roughly 15% of all antibodies in the body and is found not only in blood but also in saliva, tears, and secretions along the respiratory and digestive tracts. Here is what the test looks at:
| Parameter | What It Tells Us |
|---|---|
| Immunoglobulin A (IgA) | The amount of IgA antibodies in your blood, reflecting how well your immune system protects mucosal surfaces such as the gut and respiratory tract |
Why Is an Immunoglobulin IgA Test Done?
A doctor may request this test for several reasons, from investigating ongoing symptoms to tracking a known condition.
Common Symptoms That May Require This Test
The following symptoms are among the most common reasons a doctor may ask for an IgA blood test:
- Frequent sinus infections or chronic sinusitis
- Recurrent throat and ear infections, including strep throat
- Respiratory infections such as pneumonia or bronchitis
- Persistent diarrhoea or repeated gastrointestinal infections
- Unexplained fatigue alongside signs of poor immune function
- Suspected allergic or autoimmune symptoms
Conditions This Test Can Help Detect
The test can help identify several conditions, including:
- Selective IgA deficiency, the most common primary immune deficiency in people
- Long-term or recurrent infections
- Autoimmune conditions such as rheumatoid arthritis, systemic lupus erythematosus (SLE), and coeliac disease
- IgA nephropathy (Berger's disease), a kidney condition involving IgA deposits
Immunoglobulin IgA Test for Chronic Disease Monitoring
Doctors may use the Immunoglobulin IgA test to track how well treatment is working for conditions such as coeliac disease, lupus, and IgA nephropathy. Repeat testing is typically done every 3 to 6 months, depending on the clinical situation and the doctor's assessment.
How to Prepare and What to Expect
Preparation for the Immunoglobulin IgA test is straightforward, and the procedure itself takes only a few minutes.
Do You Need to Fast?
No, fasting is not required. You can eat and drink as normal before your appointment. If your doctor has ordered other tests alongside this one, check whether any of those require fasting.
Practical Tips Before Your Test
Keep the following points in mind before going for your Immunoglobulin IgA test:
- Bring a detailed clinical history, including your symptoms, previous test results, and any relevant medical records, as this is required for the test.
- Tell your doctor or the collection staff about all medicines you are currently taking, as some can affect results.
- Drink plenty of water before your appointment to stay well hydrated.
- Wear a loose-fitting top or a top with sleeves that roll up easily for simple access to your arm.
Step-by-Step Procedure
Here is what to expect during the Immunoglobulin IgA test procedure:
- A trained phlebotomist will clean the inside of your elbow with an antiseptic wipe.
- A small needle is inserted into a vein in your arm, and around 3 ml of blood is drawn into a special gel tube.
- You may feel a brief sting as the needle goes in. The collection itself takes less than five minutes.
- A cotton ball or small bandage is placed over the site to stop any minor bleeding.
- The sealed sample is stored at refrigerated temperature and sent to the laboratory for analysis.
- Results are typically ready within a day.
Factors That Can Affect Accuracy
The following factors may influence your IgA levels:
- Certain medications, including immunosuppressants, corticosteroids, some anti-rheumatic drugs, antiepileptic medicines, and ACE inhibitors
- Recent vaccinations or active infections at the time of testing
- Excessive alcohol consumption
- Age, as IgA levels are naturally lower in infants and young children
Understanding Your Immunoglobulin IgA Test Results
Your results should always be reviewed in the context of your full medical history. The table below provides general reference ranges to guide your understanding.
| Parameter | Normal Range | Unit |
|---|---|---|
| IgA (Adults) | 60 to 400 | mg/dL |
| IgA (Children) | Varies by age (lower in infants, increases with age) | - |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
A level below 7 mg/dL in an individual over four years of age, alongside normal IgG and IgM levels, may point to selective IgA deficiency.
Results During Special Conditions
Results can be affected by temporary or ongoing health factors. Active infections and inflammatory flares may cause IgA levels to fluctuate. Certain medications, particularly immunosuppressants and corticosteroids, can lower IgA production. Age also plays a role, as IgA levels are lower in infants and rise gradually through childhood into adulthood.
How to Maintain Healthy Levels
The following general wellness tips may support overall immune function:
- Eat a balanced diet that includes plenty of fruits, vegetables, and whole grains.
- Practise regular handwashing and good hygiene to reduce the risk of infections.
- Limit alcohol intake, as excessive consumption may affect immunoglobulin levels.

Frequently Asked Questions
The Immunoglobulin IgA test measures the level of IgA antibodies in the blood. IgA is an important antibody that protects the body’s mucosal surfaces, such as the lungs, gut, saliva, and tears. This test helps doctors assess immune system function and is used to investigate recurrent infections, diagnose immune deficiency disorders such as selective IgA deficiency, and support the diagnosis of autoimmune conditions such as coeliac disease. The results are always interpreted alongside symptoms and other medical tests.
The test involves a routine blood draw, which most people find only mildly uncomfortable. You may feel a brief sting when the needle is inserted, and there may be slight tenderness or a small bruise at the site afterwards. Both settle quickly in most cases.
A low IgA level may indicate an immune deficiency such as selective IgA deficiency or, in rarer cases, common variable immunodeficiency (CVID). These conditions can increase the risk of recurrent respiratory and gastrointestinal infections. However, a low IgA result does not always indicate illness, as some people have low levels without symptoms. Your doctor will decide whether further tests are needed based on your full clinical history.
The total Immunoglobulin IgA test does not directly diagnose coeliac disease. Instead, it is used to check IgA levels so that coeliac-specific antibody tests, such as tissue transglutaminase (tTG-IgA), can be interpreted accurately. If total IgA is normal, the tTG-IgA test is considered reliable for screening coeliac disease.
This depends on why the test was ordered. For patients with known autoimmune or immune deficiency conditions, repeat testing every 3 to 6 months may be recommended to track disease progression or treatment response. A single out-of-range result is generally confirmed with a repeat test before any significant follow-up steps are taken.
Yes, Immunoglobulin IgA test home collection is available. A trained phlebotomist will visit your home at your chosen time to collect the blood sample. The sample is then transported to a NABL-accredited laboratory for analysis, and your report is sent digitally once ready.
