Selective IgA deficiency

Diagnosis

Diagnosis confirmation usually involves blood tests to assess IgA levels. Low IgA levels commonly indicate selective IgA deficiency. These tests are particularly important for individuals prone to frequent infections or autoimmune issues.

Selective IgA deficiency typically presents without symptoms and is often incidentally discovered during testing for other health conditions, such as celiac disease.

Treatment

While there is no cure for selective IgA deficiency, some children may outgrow the condition during their early years. In most cases, treatment may not be necessary unless frequent infections occur.

Management involves addressing associated conditions. Antibiotics may be prescribed to manage infections linked to selective IgA deficiency and to prevent recurring infections.
