Measure your IgA levels accurately with our Immunoglobulin A blood test to monitor immune function and safeguard your health.
Immunoglobulin A (IgA) is a crucial antibody that plays a vital role in the immune system, primarily functioning in the mucous membranes lining the gut and respiratory tract. It serves as the body's first line of defence against harmful pathogens like bacteria and viruses. The IgA Blood Test measures the levels of IgA antibodies in your blood, providing a snapshot of your immune system's health. This test is particularly useful for individuals experiencing recurrent infections, gastrointestinal issues, or symptoms of autoimmune disorders. Elevated or decreased levels of IgA can be indicative of underlying health conditions such as celiac disease, liver diseases, or certain types of blood disorders. By assessing the levels of IgA in your blood, this test offers a comprehensive overview of your immune system's current state.
