摘要： The present invention is directed to a method for detecting hepatic diseases which are associated with fibrosis by determining the level of human prolyl hydroxylase in a serum sample which comprises:(a) contacting a serum sample of a patient suspected of having said hepatic disease associated with fibrosis with a monoclonal antibody specific to the .beta.-subunit of human prolyl hydroxylase to form an antigen antibody complex bound on a solid support;(b) contacting said antigen antibody complex bound on said solid support with an enzyme-labeled monoclonal or enzyme-labeled polyclonal antibody specific to human prolyl hydroxylase to form an antibody antigen enzyme-labeled antibody complex; and(c) measuring the amount of enzyme activity of said bound antibody antigen enzyme-labeled antibody complex to determine the level of human prolyl hydroxylase present in said serum sample.
