Interpretive Data:
The presence of smooth muscle antibodies (SMAs) and/or antinuclear
antibodies (ANAs) is consistent with a diagnosis of chronic autoimmune
hepatitis, in patients with clinical and/or laboratory evidence of
hepatocellular damage.
The presence of anti-mitochondrial antibodies (AMAs) is consistent with a diagnosis of primary biliary cirrhosis, in patients with clinical and/or laboratory evidence of hepatobiliary damage.
The presence of anti-mitochondrial antibodies (AMAs) is consistent with a diagnosis of primary biliary cirrhosis, in patients with clinical and/or laboratory evidence of hepatobiliary damage.
