Quest / Inflammation & Immune Markers
Smooth Muscle Antibody (SMA)
The Smooth Muscle Antibody (SMA) test checks for autoantibodies — proteins made by your immune system that mistakenly target the smooth muscle in your body. These muscles line organs like your intestines, blood vessels, and bladder — but when the immune system goes off course, these antibodies can cause inflammation and tissue damage.
