| neutralization | 1. The act or process of neutralising, or the state of being neutralized. 2. <chemistry> The act or process by which an acid and a base are combined in such proportions that the resulting compound is neutral.

| neutralization plate | A metal plate used for the internal fixation of a long bone fracture to neutralise the forces producing displacement. (05 Mar 2000) |
| neutralization tests | Titration of an antiserum by testing a series of dilutions of virus or immune serum to a given end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (cpe) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (id50) or die (ld50).

| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| serum bactericidal test | Method of measuring the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy. It is used to monitor the therapy in bacterial endocarditis, osteomyelitis and other serious bacterial infections. As commonly performed, the test is a variation of the broth dilution test.

| antilymphocyte serum | Immunoglobulins raised xenogeneically against lymphocyte populations. Referring particularly to antisera recognising one or more antigenic determinants on T-cell populations. Of use in experimental immunosuppression. (18 Nov 1997) |
| antirabies serum | A sterile solution containing antibodies obtained from the blood serum or plasma of a healthy animal, or human, that has been immunised against rabies by means of vaccine; administered immediately after severe or multiple bites by domestic animals suspected to be rabid and in all wild animal bites, to be followed by a regimen of rabies vaccine.
