text: Laboratory findings suggestive with the diagnosis of autoimmune polyendocrine syndrome (APS) include testing for the presence of autoantibodies (serology) followed by functional testing. Patients are tested for autoantibodies such as antibodies against 21-hydroxylase, 17-hydroxylase, glutamic acid decarboxylase (GAD), islet cell, thyroid peroxidase (TPO), TSH receptor and thyroid-stimulating immunoglobulins (TSI). Other tests include thyroid function test, adrenal function test, electrolytes, blood glucose,  complete blood count (CBC) and vitamin B12.
