DIAGNOSTIC_TEST

Patients co-infected HBV/HDV

Step 1: collection of SNDS data from 2016 to 2020 Snapshot of the prescription of the Delta tests and the tests usually prescribed simultaneously (HBV but also HIV and HCV) in one year. The investigator will collect the number of tests performed once for a given patient: anti-HDV, HDV RNA, HBsAg, anti-HCV, anti-HIV, and for each test, the description of the profile and the geographical distribution of prescribers in the metropolitan area; the description of age and sex of the patients screened. Step 2: collection of anti-HDV and RNA tests performed in French private and Public laboratories over the year 2019 Anti-HDV and HDV RNA are subcontracted by most private laboratories to two specialized biology companies. Number of HDV tests prescribed, technique used, number of positive tests and name of the requesting laboratory will be collected. The investigator will then go back to the prescriber of the positive tests, identify the patient, his epidemiological profile and his medical care.
