The Smooth Muscle Antibody (SMA) test is a diagnostic tool used to detect specific antibodies in the blood associated with autoimmune liver diseases.
What does it mean to have a positive smooth muscle antibody?
A positive smooth muscle antibody (ASMA) suggests autoimmune activity, potentially indicating conditions like autoimmune hepatitis or other autoimmune disorders.
What is anti smooth muscle antibody and ANA?
Anti-Smooth Muscle Antibody (ASMA) targets liver and muscle cells, while ANA (Antinuclear Antibody) targets cell nuclei. Both are markers for autoimmune diseases.
What does a smooth muscle antibody of 1:40 mean?
A smooth muscle antibody titer of 1:40 is considered within the normal range in many labs. Higher titers may indicate autoimmune activity.
