WebA positive direct antiglobulin test (DAT) with polyspecific antihuman globulin (AHG) generally indicates that the red cells are coated in vivo with immunoglobulin and/or complement. To differentiate the reaction, monospecific AHG reagents are used, such as anti-IgG, -IgA, -IgM, -C3, -C3b, -C3c, -C3d and -C4. ID-Card (Id-n°: 50560): WebThe AHG serum that is routinely used by most labs for pretransfusion IATs is monospecific anti-IgG. When doing DATs to detect in vivo sensitization with IgG or C3, blood banks must use polyspecific AHG serum containing anti-IgG, anti-C3b, and anti-C3d. Preparation and Source of AHG Serum Indirect Antiglobulin Test (IAT, IDC, IAGT) WebWhen using polyspecific antihuman globulin (AHG) reagents to detect unexpected antibodies or for crossmatching, reactivity in the AHG phase may be due exclusively to the AHG anticomplement component. A lengthy evaluation may be needed to prove that the reactivity is caused by a "nuisance" antibody, one that is clinically insignificant. flirt in tagalog
