Immunoglobulin A

Elevated Immunoglobulin A (IgA) levels might mean that your immune system is working extra hard to protect your body from harmful substances like bacteria and viruses. This could be due to various reasons, such as fighting an infection, dealing with inflammation, or managing an autoimmune condition like celiac disease or lupus. Some medications, like corticosteroids or immunosuppressants, can also cause higher IgA levels. While increased IgA levels can show that your body is doing its best to defend itself, it might also point to an overactive immune response that could require further investigation.

Symptoms of high levels of IgA may not be specific and can vary widely, but they could include frequent infections, fatigue, digestive issues, or skin rashes.

Having low Immunoglobulin A (IgA) levels might mean that your body's defense system, especially in the moist linings of your breathing and digestive systems, isn't as strong as it should be. This could be due to various reasons, such as ongoing stress, not eating well, not getting enough sleep, or taking certain medications that can weaken your immune system. It might also point to a condition called Selective IgA Deficiency, which is fairly common and often mild, but can make you more prone to infections in areas like your lungs, sinuses, and gut.

Symptoms of low levels of IgA could include frequent respiratory infections, digestive issues, allergies, and possibly autoimmune disorders. However, some individuals may not experience any noticeable symptoms at all.
