Antismooth Muscle Antibodies (ASMA)

ASMA stands for Anti-Smooth Muscle Antibodies, which are autoantibodies that can be detected in the blood of people with certain autoimmune and liver diseases. ASMA blood test is used as a diagnostic tool for autoimmune hepatitis (AIH) and chronic hepatitis. AIH is a chronic liver disease in which the immune system attacks and damages liver cells, leading to inflammation, scarring, and eventually liver failure. The ASMA blood test can help diagnose AIH and differentiate it from other liver diseases that have similar symptoms. It is important to note that a positive ASMA test does not necessarily mean that a person has AIH or any other liver disease. Additional tests and a thorough medical evaluation are required to confirm the diagnosis.

There is an additional £20 phlebotomy fee for every donation.
