What does a low IGA serum mean?

A low serum IgA (Immunoglobulin A) level may indicate a deficiency in the body's immune system, making an individual more susceptible to infections, particularly in mucosal areas such as the respiratory and gastrointestinal tracts. It can be a primary condition, known as selective IgA deficiency, or secondary to other health issues. While many individuals with low IgA may remain asymptomatic, some may experience recurrent infections or autoimmune disorders. It's important to consult a healthcare professional for proper evaluation and management.
