Smooth muscle antibodies (SMA) are autoantibodies produced by the body that attack its own actin, a protein found in tissues, especially the liver. SMA or F-actin antibody tests help diagnose and differentiate autoimmune hepatitis type 1 and type 2.
Liver kidney microsome type 1 (anti-LKM-1) antibodies target the body’s own enzyme CYP2D6 found primarily in liver cells. The anti-LKM-1 test helps diagnose autoimmune hepatitis and differentiate between type 1 and type 2.
Thyroid Antibodies testing can help determine if your immune system and thyroid are functioning properly. It’s often used to diagnose Graves’ disease or Hashimoto’s thyroiditis.
Tests for extractable nuclear antigens (ENA) antibodies help distinguish between autoimmune disorders, such as lupus, scleroderma and Sjogren syndrome.
