Mitochondrial Antibody Blood Test (Labcorp)
This test measures the level of Antimitochondrial Antibodies (AMA) in the blood. AMA's are a type of autoantibody which are primarily associated with the condition Primary Biliary Cirrhosis (PBC). PBC is an autoimmune disorder that causes inflammation of the bile ducts in the liver. There are 9 varieties of Mitochondrial antibodies which are designated M1-M9. M2 is the type that is most likely to cause illness and most closely associated with cases of PBC. Testing for mitochondrial antibodies can aid in diagnosing PBC as well as differentiating it from other conditions that cause liver damage.
AMA testing is typically ordered when someone has symptoms of PBC which can include fatigue, jaundice, abdominal pain, itching, and inflammation of the liver. It may be ordered along with other tests such as an antinuclear antibody (ANA) and an actin smooth muscle antibody (ASMA).
Turnaround for this test is typically 1-3 business days.
