seroconversion

Immunology The development of antibodies detectable in the serum, after exposure to a particular organism or antigen, in a person who was previously immunologically 'naive' for–ie, previously unexposed to a particular antigen; seroconversion may indicate current infection–and transmissibility of a pathogen–eg, HIV-1–seroconversion to p24 and/or p41 antibody production or HBV–seroconversion to surface antibody-HBsAb or e antibody–HBeAb production. See Seropositive. Cf Seronegative.

se·ro·con·ver·sion
