This would be a false positive test result.

Anti-HBs less than 5 mIU/mL: Negative for HBV infection, but susceptible and hence requires vaccination.

Difference Between Antiserum and Antibody

The key difference between antiserum and antibody is that antiserum is the blood serum we obtain from an immunized host, while antibody is an immunoglobulin protein that detects the presence of antigens and aid in neutralizing them. Moreover, antiserum contains water, antibodies, dissolved solutes, etc., while antibody is a protein molecule.
