AMA (Antimitochondrial Antibody) and AMA M2 Test For Liver Diseases

AMA and AMA M2 Test diagnose liver diseases like primary biliary cholangitis by detecting specific antibodies attacking the mitochondria in liver cells.

AMA and AMA M2 Test

Here are the basic details of the AMA and AMA M2 Test.

*Test Price range may vary as per location, lab type, and procedure of lab test.

AMA and AMA M2 Test Means

The AMA and AMA M2 Test identifies antibodies targeting mitochondria in the body.

• It is particularly valuable for diagnosing primary biliary cirrhosis (PBC).
• This autoimmune liver disease can be detected through the presence of AMA antibodies, particularly AMA M2.
• The test assists in early PBC diagnosis, allowing for timely treatment.
• Antimitochondrial Antibody and AMA M2 results help in assessing liver function and disease severity.
• Diagnosis and monitoring of PBC are based on the outcomes of this test.

AMA and AMA M2 Test Purpose

The purpose of the AMA and AMA M2 Test is to:

• Identify antibodies targeting mitochondria in the body.
• Diagnose autoimmune liver disease, particularly PBC.
• Enable early detection and timely treatment of PBC.
• Assess liver function and disease severity.
• Guide diagnosis and monitoring of PBC.
• Support the development of a treatment plan for PBC.

AMA and AMA M2 Test Result

Here is the basic meaning of AMA and AMA M2 Test Result.

• Positive Result: A positive result suggests the presence of antimitochondrial antibodies, which are associated with primary biliary cholangitis (an autoimmune liver disease).
• Negative Result: A negative result typically means a lower likelihood of primary biliary cholangitis.
• AMA-M2: This subtype of antibodies is more specific for the disease.
• Consult a Hepatologist: If you have a positive result, it's important to consult a hepatologist for further evaluation and management.

AMA and AMA M2 Test Normal Result

Here is the normal result of the AMA and AMA M2 Test

A negative result for both of these tests is within the normal range, indicating the absence of these specific antibodies in the blood, which is a typical finding in individuals without PBC. If the result is positive, it may suggest the potential presence of PBC and would require further evaluation by a healthcare professional.
