FAQs
What are smooth muscle antibodies?
Smooth muscle antibodies (SMA) are antibodies produced by your immune system which are directed against proteins of the smooth muscle.
What can I learn from an SMA test?
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.
What is a Smooth Muscle Antibodies Blood Test?
Our Smooth Muscle Antibodies Blood Test is usually used to help diagnose autoimmune hepatitis and distinguish it from other causes of liver disease or injury.
