A biobank will be opened at V laboratory Aarhus University hospital in an appropriate freezer. The material will be analyzed in small batches in order to avoid inter assay differences. The liver biopsy will be examined for histology the same day. After the project has come to an end any leftover material (blood or tissue) will be placed in a biobank for further research, should this prove valid and the research subject accept. Urine samples will be analyzed immediately and not preserved.
