QUESTION FOR HEPATOLOGISTS: Could two Fibroscans and 3 ultrasounds miss advanced liver cirrhosis? Biopsy is out of the question

Reasonable test. If biopsy if unreasonable, the a fibroscan is a reasonable alternative. It is quite specific, meaning that if you are low value/result that it's unlikely that you have advanced fibrosis/cirrhosis, the actual percentage or specificity value, depends on your cut off point. So if you provide your specific results docs here may be better able to guide you.
