I had a Fibrosure blood test that indicated that I had F 4 Cirrhosis. I have read online that this is a highly reliable test for cirrhosis. Does anyone know anything about the Fibrosure test? I am scheduled to have an MRI, blood tests and liver biopsy at Mayo soon. I have also read that the Fibroscan test is more reliable than a biopsy in diagnosing cirrhosis because the Fibroscan gives the "big picture" of the liver while the biopsy only tests a small sample of the liver. Does anyone know anything about this?
