The AMA M2 test is a specific blood test used to identify AMA subtype M2, which is particularly associated with primary biliary cholangitis. This test helps in confirming the diagnosis of PBC and distinguishing it from other liver conditions.
How is the AMA M2 test performed?
The AMA M2 test is a simple blood test. A healthcare professional will draw a small blood sample from your arm, and the sample will be analyzed in a laboratory to check for the presence of AMA subtype M2.
Is the AMA M2 test the only diagnostic tool for PBC?
No, the AMA M2 test is a crucial tool for diagnosing PBC, but it is typically used in conjunction with other tests, such as liver function tests, imaging studies, and liver biopsies, to confirm the diagnosis and assess the extent of liver damage.
