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

(sēr'ō-kŏn-vĕr'zhŭn)
The process by which, after exposure to the etiologic agent of a disease, the blood changes from a negative to a positive serum marker for that specific disease.

Seroconversion

The change from HIV-negative to HIV-positive status during blood testing. Persons who are HIV-positive are called seroconverters.
