Bland–Altman analyses of relative deviations (all study participants). (A) Deviation analysis of absolute CD4 cell count (AbsCD4) in venous blood measured using the BD FACSPresto system and AbsCD4 in venous blood measured using the reference standard (BD Tritest kit and BD FACSCalibur system). (B) Deviation analysis of AbsCD4 in capillary blood measured using the BD FACSPresto system and AbsCD4 in venous blood measured using the reference standard (BD Tritest kit and BD FACSCalibur system). (C) Deviation analysis of CD4 T lymphocyte percentage of all lymphocytes (CD4%) in venous blood measured using the BD FACSPresto system and CD4% in venous blood measured using the reference standard (BD Tritest kit and BD FACSCalibur system). (D) Deviation analysis of CD4% in capillary blood measured using the BD FACSPresto system and CD4% in venous blood measured using the reference standard (BD Tritest kit and BD FACSCalibur system). (E) Deviation analysis of hemoglobin concentration (Hb) in venous blood measured using the BD FACSPresto system and Hb in venous blood measured using the reference standard (Sysmex XT-4000i analyzer). (F) Deviation analysis of Hb in capillary blood measured using the BD FACSPresto system and Hb in venous blood measured using the reference standard (Sysmex XT-4000i analyzer).
