I am not a doc but I don't think you have anything to worry about. Here are comments from a pathology lab.
" Smooth muscle antibody measurements are useful in confirming the diagnosis of chronic active hepatitis (CAH). Titers generally range from 1:80-1:320 and persist for years."
Hummm never has those tests done first I have heard of them.
I had hep c for 37 years before I was cured 2.5 years ago with Harvoni my 5th treatment for hep c. I have been living with liver cirrhosis for the last 9.5 years. My cirrhosis was diagnosed with liver biopsy.
As far as I know I have never had those tests done.
Best of luck on treatment
"Please Note:
All samples that are positive for Smooth Muscle Antibodies (SMAs) are titred at 1:40, 1:80 and 1:160. This is requested by the laboratory.
A low titre (1:40) Smooth Muscle Antibody (SMA) can often be associated with increased age, infection, malignancy, Primary Biliary Cirrhosis, Chronic Viral Hepatitis, and Alcoholic Chronic Hepatitis.
A higher titre (1:80 and 1:160) Smooth Muscle Antibody (SMA) is often associated with Chronic Active Autoimmune Hepatitis....."
