Changes in serum C-reactive protein levels in dogs with various disorders and surgical traumas.

ABSTRACT

The serum levels of C-reactive protein (CRP) produced as an inflammatory response in dogs with various disorders and surgical traumas were measured by enzyme-linked immunoabsorbent assay and slide reversed passive latex agglutination test (RPLA). The CRP levels were greatly increased 1-2 days after surgery in most of the dogs (n = 29) subjected to surgery. These levels had markedly decreased by the time the sutures were removed. In dogs with various disorders (n = 58), the serum CRP levels at first diagnosis were high in infectious diseases. In dogs from which paired serum samples were examined, the serum CRP usually showed a decrease with improvement in the condition (n = 11) or a terminal increase (n = 4) but, conversely, some showed an increase with improvement in the condition (n = 3).
