AMA (Antimitochondrial Antibodies)

What is the Anti-AMA Antibodies Blood Test?

The Anti-AMA Antibodies Blood Test is a laboratory test used to detect antimitochondrial antibodies (AMA) in the blood. AMA are specific antibodies directed against proteins in the mitochondria of cells. This test is particularly important for the diagnosis of Primary Biliary Cholangitis (PBC), an autoimmune disease affecting the liver.

Why should you have the Anti-AMA Antibodies Blood Test done?

This test is essential for people experiencing symptoms that may indicate PBC, such as fatigue, itching, dry eyes and mouth, and upper abdominal pain. Early detection of AMA can help establish the diagnosis of PBC, enabling early treatment to manage the progression of the disease.

What does it indicate?

A positive result for the Anti-AMA Antibodies Blood Test indicates the presence of AMA in the blood, which is a strong indication of PBC. It is a crucial component of the diagnosis, along with other clinical assessments and laboratory tests.

What does a positive result mean?

A positive result indicates the presence of AMA, which in most cases points to PBC. This result is an important diagnostic criterion for PBC and requires further evaluation and possible treatment by a specialist.

What does a negative result mean?

A negative result means that no AMA were detected in the blood sample. This may suggest the absence of PBC, but other factors and symptoms must also be considered. It is important to undergo a full medical evaluation if symptoms indicative of liver disease are present.
