SMAT (Smooth Muscle Antibody titers) refer to the measurement of the concentration or level of anti-smooth muscle antibodies in a patient’s blood serum. The titer provides information about the amount or concentration of these antibodies in the blood.

SMA titration is typically performed through laboratory testing, using techniques such as indirect immunofluorescence (IIF) or enzyme-linked immunosorbent assay (ELISA). These tests allow for the quantification of ASMA antibodies by comparing the patient’s serum to known standards or controls.

If SMA is found in your blood, you probably have autoimmune hepatitis. Autoimmune hepatitis is a disease in which the immune system attacks liver tissues. There are two types of autoimmune hepatitis:

Type 1, the most common form of the disease. Type 1 affects more women than men. It is also more common in people who also have another autoimmune disorder.
Type 2, a less common form of the disease. Type 2 mainly affects girls between the ages of 2 and 14.

Autoimmune hepatitis can be controlled with medications that suppress the immune system. Treatment is most effective when the disorder is detected early. Without treatment, autoimmune hepatitis can cause serious health problems, such as cirrhosis and liver failure.
