Immunoglobulin A (IgA) is an antibody class with an important role in mucosal immunity. The IgA secretory form is present in numerous secretions from the lungs, tears and salivary glands. The IgA test is most frequently ordered when a plasma cell cancer is suspected or in the evaluation of immune function. IgA is included in the immunoglobulin panel or it may be requested individually.
