This was a prospective, single center, double blind observational study of diagnostic accuracy of an inflammatory and immune panel in sepsis.
C-reactive protein, procalcitonin, and neutrophil CD64 individually accurately discriminated early sepsis and infection in the critically ill patients.
The absolute lymphocyte count by flow cytometry (CD45+) and the frequency of monocytes expressing HLA-DR as well as HLA-DR expression on monocytes while significantly lower were not sufficiently good as discriminators for sepsis
The combination of C-reactive protein, procalcitonin, and neutrophil CD64 improved the diagnostic accuracy of sepsis.
