Cytological and biochemical correlates of viral NAAT results. (A) CSF protein levels were higher in HSV-1/2- and VZV-positive samples but not in CMV- or EV-positive samples. (B) CSF glucose concentrations were lower in HSV-1/2-positive samples than in negative samples. (C) CSF RBC counts were higher in HSV-1/2-positive samples than in negative samples. (D) CSF nucleated cell counts were higher in NAAT HSV-1/2-, VZV-, CMV-, and EV-positive samples. (E) CMV- and EV-positive samples had reduced CSF lymphocyte counts, relative to negative samples, while HSV-1/2-positive samples had relative lymphocytosis. (F) EV-positive samples had increased CSF neutrophil counts, relative to EV-negative samples. Dashed lines, upper and lower limits (0 if not shown) of the reference ranges. No reference range was established for CSF glucose levels. Solid line in panel D, proposed nucleated cell count acceptance criterion. Whiskers, 2.5% and 97.5% limits. Dots, outliers.
