# Antiextractable Nuclear Antigens

> This test measures specific antibodies in your blood that target proteins found inside the nucleus of your cells. It helps show whether your immune system is attacking healthy tissue, which is often the cause of symptoms like joint pain, fatigue, or rashes. These results assist doctors in distinguishing between different autoimmune disorders, such as Lupus or Mixed Connective Tissue Disease. However, a positive result does not confirm a diagnosis by itself and requires further evaluation of your medical history.
