| Additional Information | Most hepatitis of unknown origin will have been due to hepatitis A or hepatitis E (or non-viral causes).
Additional testing for those who give a history of hepatitis between 12 and 24 months previously ensures anti-HBc testing is carried out, to exclude hepatitis B infection.
After 24 months, donation testing for anti-HBc will be carried out routinely, as it will be at least two years since the donor last gave a blood donation or samples for testing by the transfusion service. These guidelines will be revised if policy for anti-HBc testing changes.
