Smooth muscle antibodies (SMA) are antibodies produced by your immune system which are directed against proteins of the smooth muscle.
Our test can help you investigate the cause of liver disease, as the presence of SMAs are strongly associated with autoimmune hepatitis. SMAs are also much less common in other forms of liver disease, such as primary biliary cirrhosis, and viral infections, such as hepatitis B.
