Delayed orthopedic joint prosthesis infections (DOJP-Is) due to staphylococci frequently result in prosthetic revision. Specific and noninvasive diagnostic tests are unavailable, and DOJP-Is are commonly diagnosed at advanced stages of disease. An enzyme-linked immunosorbent assay (ELISA) was developed to detect serum antibodies against staphylococcal slime polysaccharide antigens. Using a cutoff of 0.35 ELISA units, the test showed a specificity of 95.1% (95% confidence interval [CI], 85.4 to 98.7%) and a sensitivity of 89.7% (71.5 to 97.3%) on a sample of 90 individuals.
