Deming regression analyses (all study participants). (A) Correlation between 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) Correlation between 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) Correlation between 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) Correlation between 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) Correlation between 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) Correlation between Hb in capillary blood measured using the BD FACSPresto system and Hb in venous blood measured using the reference standard (Sysmex XT-4000i analyzer).
