An immunoglobulin A test measures the level of immunoglobulin A (IgA) in your bloodstream. This test is recommended to identify whether you are at a risk of developing any autoimmune disease and other malignancies, such as cancers that affect the bone marrow, blood and immune system, chronic infections, and genetic disorders. This test is administered along with IgG test to arrive at conclusive and holistic diagnostic results.

Immunoglobulin A are the most commonly found antibodies in your body, produced by your immune system to identify and eliminate germs. These antibodies are vital in protecting your digestive system and respiratory tract from potential infections. The IgA levels in your body are usually high around the gastrointestinal tract, respiratory passages, saliva, gastric juices and mucous membranes.  

Learn everything about IgA Testing before you book your test online. Understand the why, how, and what of this test. 

Why Do I Need IgA Blood Test? 

Your primary healthcare physician will recommend an IgA level test if you have any sort of infection, particularly in the intestines, stomach, lungs, and sinuses. 

Opt for an IgA test right away if you or your loved ones experience: 

  • Infections in the Sinus, throat and ear
  • Respiratory infections, such as bronchitis and pneumonia - These respiratory tract and lung infections are usually caused by bacterial agents. 
  • Infections caused by Cytomegalovirus:  A virus related to chicken pox can lead to these infections. 
  • Yeast infections in the mouth, eyes, or the digestive tract  
  • IgA nephropathy symptoms: Blood in the urine (hematuria), pain in the sides of your back, swelling in the ankles (oedema) and high protein content in the urine (proteinuria) are some of the key symptoms of IgA nephropathy. 
  • HIV/AIDS: In case of an HIV/AIDS infection, the natural production of IgA gets compromised, which disbalances the IgA:IgM ratios in the mucosal fluids.  
  • Persistent diarrhoea 
  • Unintentional weight loss 
  • Skin rashes and other allergies 

You will also be recommended to go for this diagnostic IgA blood test if your physician suspects you to be at risk due to your past medical history or family history.    

How To Prepare For IgA Blood Test?

To prepare for IgA Test, follow these steps: Consult your healthcare provider, inform them about medications, avoid intense exercise, follow fasting instructions if given, and provide accurate medical history.

  • As per the scheduled time of the blood test, a lab technician who usually takes blood samples will arrive.
  • A thin needle will be used to draw blood from your arm’s vein.
  • The needle might cause a mild pinch and some discomfort.
  • The lab technician then fills a collection tube with blood and then removes the needle from the skin.

What Does Immunoglobulin A Test Results Mean?

Thus, getting your IgA blood test results checked out by your doctor is crucial for better interpretation.

FAQ Around IgA Test

IgA deficiency is a medical condition where a person has lower than normal levels of Immunoglobulin A (IgA) antibodies in their blood, leading to a potential increased susceptibility to infections in the respiratory and gastrointestinal tracts.

To reduce high IgA levels, focus on a diet rich in fresh fruits, vegetables, probiotics, omega-3 fatty acids, vitamin C, and zinc. Limit alcohol and processed foods. Stay hydrated with water and regularly monitor with healthcare providers.

IgA deficiency's seriousness varies. While some experience mild effects, others may face increased infection risks. Early diagnosis and management are vital.

Selective IgA deficiency is more prevalent among Caucasians (of European descent), with an estimated occurrence of 1 in 500 individuals. However, incidence rates may vary based on geographical location and ethnic background

Yes, IgA deficiency is considered a primary immunodeficiency. It is characterized by lower than normal levels of Immunoglobulin A (IgA) antibodies, which are crucial for immune defense, especially in the mucous membranes. Primary immunodeficiencies are usually genetic and occur due to defects in the immune system's development or function. IgA deficiency is one of the most common primary immunodeficiency disorders.

IgA deficiency is not curable, but complications can be managed. Prophylactic antibiotics and immunoglobulin replacement therapy may be used in some cases to reduce infection risks.
