What is an anti smooth muscle antibody test?

Anti-smooth muscle antibody is a blood test that detects the presence of antibodies against smooth muscle. The antibody is useful in making a diagnosis of autoimmune hepatitis.

What is F-actin AB IgG?

Actin (Smooth Muscle) Antibody (IgG) – Actin is the major antigen to which smooth muscle antibodies react in autoimmune hepatitis. F-Actin IGG antibodies are found in 52-85% of patients with Autoimmune Hepatitis (AIH) or chronic active hepatitis and in 22% of patients with Primary Biliary Cirrhosis (PBC).

What is a positive smooth muscle AB with reflex titer?

If your results show a high amount of SMA antibodies, it probably means you have the type 1 form of autoimmune hepatitis. A lower amount may mean you have the type 2 form of the disease. If no SMAs were found, it means your liver symptoms are being caused by something different than autoimmune hepatitis.

What is Asma positive?

The presence of ASMA in the blood indicates that a person may have autoimmune hepatitis or another disease that damages the liver.

Can a fatty liver cause a positive ANA?

Up to 30% of patients with non-alcoholic fatty liver disease (NAFLD) may have antinuclear antibodies (ANA). Low titre (<1:320) ANA positivity is not uncommon, but a high titre is rare. The ANA titre does not correlate with the histological grade of NAFLD.

What causes anti smooth muscle antibody?

An ASMA test looks for the one type of autoantibody that attacks smooth muscle. Anti-smooth muscle antibodies are found in autoimmune liver diseases such as primary biliary cholangitis and autoimmune hepatitis (AIH).

What is actin smooth muscle antibody test for?

The smooth muscle (SMA) or actin antibody test is primarily ordered along with antinuclear antibodies (ANA) and liver kidney microsomal type 1 (LKM-1) antibodies to help diagnose autoimmune hepatitis and to differentiate between the two major types of autoimmune hepatitis, type 1 and type 2.

Can you live a normal life with autoimmune hepatitis?

Therefore, it is possible to have a normal life expectancy, even with the life-long condition of autoimmune hepatitis.

What is smooth muscle AB titer?

A smooth muscle antibody titer of 1:80 is suggestive of a liver disease called autoimmune hepatitis. This is a disease where the immune system works abnormally and starts attacking your own body cells instead of normal things like bacteria and viruses.
