High values Levels of IgA also get higher in some autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus (SLE), and in liver diseases, such as cirrhosis and long-term (chronic) hepatitis. IgG. High levels of IgG may mean a long-term (chronic) infection, such as HIV, is present.

Is High IgA serious?
If your immunoglobulin levels are too high, it may be a sign of an autoimmune disease, a chronic illness, an infection, or a type of cancer.
What does a positive IgA test mean?
Tissue Transglutaminase Antibodies (tTG-IgA) – the tTG-IgA test will be positive in about 98% of patients with celiac disease who are on a gluten-containing diet. The test’s sensitivity measures how correctly it identifies those with the disease.
What is a normal IgA level?
The IgA normal range differs with age and the IgA normal range for an healthy adult is between 80 – 350 mg/dL.
How do I lower my IgA levels?
Your doctor may suggest steps you can take to reduce inflammation. Some complementary approaches include yoga, herbal supplements (curcumin), and following a healthy diet. Studies suggest that cocoa, avoiding heavy drinking, and refraining from fasting may also reduce inflammation and lower IgA levels.
Is IgA elevated in celiac disease?
However, 3 percent of patients with celiac disease have IgA deficiency. Therefore, if the serum IgA tTG result is negative but clinical suspicion for the disease is high, a serum total IgA level may be considered.
Does low IgA mean celiac?
What is the Connection between Celiac Disease and IgA Deficiency? An estimated 2% of people with celiac disease also have selective immunoglobulin A (IgA) deficiency. If someone has IgA deficiency and celiac disease, the IgA deficiency can cause a false negative on a celiac disease antibody test.
What IgA means celiac?
Immunoglobulin A (IgA) — this test is usually ordered along with the tTG IgA test (below) to detect IgA deficiency, which occurs in about 2-3% of people with celiac disease. If you have an IgA deficiency then the test for tTG IgA may be negative even if you have celiac disease (false-negative test results).
How long is IgA test?
An Immunoglobulin A (IgA) Blood Test is a quantitation of IgA, the chief antibody in the mucous membranes of the gastrointestinal and respiratory tract and in saliva and tears. Preparation: No special preparation required. Test Results: 2-3 days. May take longer based on weather, holiday or lab delays.
Why is my IgA low?
Autoimmune diseases, in which your immune system attacks particular organs or tissues in your own body, can be found with selective IgA deficiency. Common autoimmune conditions found with IgA deficiency include rheumatoid arthritis, lupus, celiac disease or inflammatory bowel disease.
What is considered a low IgA level?
Selective IgA deficiency is an IgA level < 7 mg/dL (< 70 mg/L, < 0.4375 micromol/liter) with normal IgG and IgM levels. It is the most common primary immunodeficiency. Many patients are asymptomatic, but some develop recurrent infections and autoimmune disorders.
Does low IgA mean immunocompromised?
Selective IgA deficiency is the most common primary immunodeficiency disease (PIDD). People with this disorder have absent levels of a blood protein called immunoglobulin A (IgA). IgA protects against infections of the mucous membranes lining the mouth, airways and digestive tract.
What is IgA kidney disease?
IgA nephropathy is a disease in which IgA protein builds up in and damages the filtering part of the kidney (glomerulus). The damage may cause few or no symptoms. Blood in the urine is the most common symptom. The condition is diagnosed by blood and urine tests. Kidney biopsy may also be needed.
Can I live a normal life with IgA nephropathy?
There’s no cure for IgA nephropathy and no definitive way of knowing what course the disease will take. Some people experience complete remission, others live normal lives with low amounts blood or protein in their urine, while some people progress to renal failure.
How serious is IgA nephropathy?
While IgA nephropathy is a lifelong disease, for most people it doesn’t progress to anything serious. Treatment typically involves controlling your blood pressure and cholesterol levels with medications. Some people with IgA nephropathy will eventually need a kidney transplant.
How is IgA treated?
Medications to treat IgA nephropathy include: High blood pressure medications. Taking angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) can lower your blood pressure and reduce protein loss. Omega-3 fatty acids.
