| indirect reacting bilirubin | The fraction of serum bilirubin which has not been conjugated with glucuronic acid in the liver cell; so called because it reacts with the Ehrlich diazo reagent only when alcohol is added; increased levels are found in hepatic disease and haemolytic conditions. Synonym: unconjugated bilirubin. (05 Mar 2000) |

| indirect retainer | A part of a removable partial denture which assists the direct retainer's in preventing occlusal displacement of the distal extension bases by functioning through lever action on the opposite side of the fulcrum line. (05 Mar 2000) |
| indirect retention | Retention obtained in a removable partial denture through the use of indirect retainers. (05 Mar 2000) |

| indirect transmission | <epidemiology> Transmission of a parasite through an indirect life cycle. (05 Dec 1998) |
| indirect vision | Vision resulting from retinal stimulation beyond the macula. Synonym: indirect vision. (05 Mar 2000) |
| affinity antibody | The measure of the interaction between molecules such as a receptor and its ligand. This interaction is reversible. (05 Mar 2000) |
| agglutinating antibody | 1. An antibody that causes clumping or agglutination of the bacteria or other cells which either stimulated the formation of the agglutinin, or contain immunologically similar, reactive antigen. Synonym: agglutinating antibody, immune agglutinin. 2. A substance, other than a specific agglutinating antibody, that causes organic particles to agglutinate, commonly qualified, e.g., plant agglutinin. (05 Mar 2000) |
| anaphylactic antibody | Antibody that has an affinity for certain kinds of cells, in addition to and unrelated to its specific affinity for the antigen that induced it, because of the properties of the Fc portion of the heavy chain. See: heterocytotropic antibody, homocytotropic antibody, cytotropic antibody test. Synonym: anaphylactic antibody, cytophilic antibody. (05 Mar 2000) |
| anti-basement membrane antibody | Autoantibodies to renal glomerular basement membrane antigens. (05 Mar 2000) |
| antibody | An immunoglobulin molecule that has a specific amino acid sequence by virtue of which it interacts only with the antigen that induced its synthesis in cells of the lymphoid series (especially plasma cells) or with antigen closely related to it. Antibodies are classified according to their ode of action as agglutinins, bacteriolysins, haemolysins, opsonins, precipitins, etc. (18 Nov 1997) |
| antibody affinity | A measure of the binding strength between antibody and a simple hapten or antigen determinant. It depends on the closeness of stereochemical fit between antibody combining sites and antigen determinants, on the size of the area of contact between them, and on the distribution of charged and hydrophobic groups. It includes the concept of "avidity," which refers to the strength of the antigen-antibody bond after formation of reversible complexes. (12 Dec 1998) |
| antibody aldolase | <enzyme> Prepared by reactive immuninization to catalyze a wide variety of aldol reactions and decarboxylations Registry number: EC 4.1.2.- Synonym: fab 33f12, aldolase catalytic antibody (26 Jun 1999) |
| antibody-coated bacteria test, urinary | Fluorescent antibody technique for visualizing antibody-bacteria complexes in urine. The presence or absence of antibody-coated bacteria in urine correlates with localization of urinary tract infection in the kidney or bladder, respectively. (12 Dec 1998) |
