Representative plots of monocyte HLA-DR measurement by flow cytometry. Monocyte HLA-DR expression was measured by flow cytometry. The samples were collected at day 3 after admission. a The left dot-plot (SSC vs. FITC) delimited the monocytic region. The right dot-plot (APC vs. FITC) delimited the CD14⁺ HLA-DR⁺ monocyte (upper right region). The analysis was performed on a patient with immunosuppression as was reflected by the decreased proportion of CD14⁺ HLA-DR⁺ monocyte (18.5%). b The same strategy of analysis was used on a patient without immunosuppression. FITC, fluorescein isothiocyanate; APC, allophycocyanin; SSC, side scatter
