Laboratory

Alpha defensins 1+2+3 [Presence] in Synovial fluid by Immunoassay

Definition

Qualitative detection of human neutrophil peptide-1, -2, and -3, also known as alpha defensins 1-3, in synovial fluid by immunoassay methods, such as ELISA or lateral flow assay, for the diagnosis of periprosthetic joint infections (PJI). This assay detects but does not differentiate between the three HNP peptides. This term was created for, but not limited in use to, Zimmer Biomet Diagnostics Synovasure Alpha Defensin ELISA and Lateral Flow Test kits. The Synovasure Lateral flow test utilizes the same anti-microbial peptide as the ELISA test to detect the immune response to infection, but the Lateral Flow returns results in 10 minute whereas the ELISA typically has a 24-48 hour result turnaround.
