RESUMO
Quantitative immunoglobulin tests are often ordered as part of the initial evaluation for suspected immune deficiency. Although alterations in immunoglobulin levels can explain recurrent infections, in a patient without symptoms, there are a variety of other factors that can alter immunoglobulin levels. Common causes for elevated immunoglobulin A levels include malignancy and hepatic impairment in addition to a variety of infiltrative, infectious, and inflammatory diseases. We present a case of a 45-year-old man with a history of recurrent sinopulmonary symptoms without bacterial infection found to have an isolated elevated level of immunoglobulin A.
