New HBV Infection Biomarkers: Clinical Characterization and Impact on Management

The intervention involves the additional and minimal collection of two blood samples during routine care procedures (9mL in a dry tube and 9mL in a Paxgene tube). These samples are specifically collected for research purposes and will be stored in the laboratory at the Henri Mondor Biobank Platform under the responsibility of Pr Bijan Ghaleh-Marzban for 15 years. The samples will be preserved under strict conditions and may be used for future analyses related to the pathology of HBV infection or other scientific advancements, with the patient's informed consent.
