The purified capsular polysaccharides (PCPs) from the most common pneumococcal serotypes that cause disease have been formulated into polyvalent vaccines, and children immunized with the vaccines develop specific antibodies against some of the serotypes (3, 7, 10, 11, 22-24, 33). (docksci.com)
or it may be passive, being acquired from transfer of antibodies from another person or from an animal, either naturally, as from mother to fetus, or by intentional inoculation (artificial passive i.), and, with respect to the particular antibodies transferred, it is specific. (theodora.com)

In the field of immunodiagnostics, antibodies are used to quantify clinical biomarkers in complex biological samples like blood (Wild, 2013). (trea.com)
The heterogeneous immunoassays are today's gold standard for clinical diagnostics. (trea.com)
Since that time, millions of HIV antibody tests have been performed in laboratories of blood and plasma collection centers, in counseling and testing centers, and in clinical facilities as well as for purposes such as screening active duty military personnel and applicants for military service.
