The antigen profile of subjects with systemic lupus erythematosus (SLE) in renal remission also characterizes subjects with SLE in acute renal relapse and those without renal involvement. A three-dimensional principal component analysis (PCA) based on the seven antigen reactivities in Table 4 is shown. Classification of the 25 subjects in acute renal relapse and those without renal involvement yields two errors – a specificity of 92% (see text). The blue star represents the profile of a subject who was healthy at the time of serum collection but who later developed SLE.
