| Comments | |||||
| For a positive result: CDC guidelines currently state that a value of >=10 mIU/mL indicates recovery from acute or chronic hepatitis B virus infection or acquired immunity from HBV vaccination. This assay does not differentiate between a vaccine-induced immune response and an immune response induced by infection with HBV. For a negative result: CDC guidelines currently state that a value of <10.00 mIU/mL indicates a lack of recovery from acute or chronic hepatitis B or inadequate immune response to HBV vaccination. | |||||
