Immunoglobulin A IgA Blood Test
Immunoglobulin A IgA Blood Test (Labcorp)
The Immunoglobulin A (IgA) test measures levels of IgA antibodies in a person's blood. Antibodies are produced by the immune system in response to various bacteria, viruses and diseases in the body. IgA antibodies are typically found in areas of the body such as the digestive tract, ears, eyes, breathing passages, saliva, tears and blood. In most people, IgA antibodies account for about 10-15% of total antibodies. Some people however have a condition which causes their body to not produce IgA antibodies.
Elevated IgA levels can be indicative of a number of conditions such as Rheumatoid Arthritis, Lupus, Cirrhosis and Hepatitis. High IgA levels may mean that a person has a condition known as Monocolonal Gammopathy. This condition may not cause immediate health concerns but has the potential of developing into a type of cancer known as Multiple Myeloma.
Some people's bodies produce very low levels of IgA antibodies or none at all. People with low IgA levels have a higher risk of developing certain type of autoimmune disorders. Low IgA can also indicate conditions such as Leukemia, kidney disease and intestinal disease.
This test may be ordered as part of a screening for certain autoimmune disorders or cancers. IgA levels are often ordered with other types of tests since IgA levels by themselves are not specific enough to pinpoint specific conditions.
For a more comprehensive screening, the Immunoglobulin IgA IgG IgM test is also available.
Turnaround for this test is typically 1-3 business days.
