“ Your fibrosis result may be over-estimated (your liver may have less scarring than what your fibrosis result says) if you have:
Liver inflammation. This can be caused by a recent liver illness or drinking alcohol.
Benign (not cancerous) or cancerous tumors in your liver.
Liver congestion (when your liver is too full of blood or other fluids). This is usually caused by heart failure.
Your FibroScan results may also be less accurate if you have:
A body mass index (BMI) higher than 30 (obesity)
A build-up of fluid in your abdomen (ascites)
Too little bile flowing out of your liver (biliary obstruction)”
