Summary
This is a Proprietary Laboratory Analyses (PLA) code, meaning that the code applies to only one unique lab test made by a specific manufacturer or performed by a specific lab. Report 0312U to be reported only for Avise® Lupus from Exagen, Inc. Using a specimen such as serum, or plasma and whole blood, the test identifies 10 biomarkers to aid in the differential diagnosis of systemic lupus erythematosus (SLE). The biomarkers include eight IgG autoantibodies associated with SLE and two cell–bound complement activation products (CB–CAPs). CB–CAPs are traces of cell–surface proteins activated as part of the complement immune system, which is the body’s first line of defense against foreign invaders.
