CD64 and NE ELISA for whole blood from patients with suspected sepsis (n=34, red squares) or ICU controls (n=9, green triangles) or healthy (n=51), blue circles). (A) Assigned cut-off for total CD64 (1.5 x Mean); 31/34 sepsis patients have levels of CD64 above these cut-offs. Arrows: These eight patients negative by Leuko64^TM flow cytometric assay were positive for Total CD64. (B) Expanded data for samples with levels of total NE <2.5 μg/ml, including the 2 neutropenic sepsis samples (red) that have elevated levels of CD64 compared to an assigned cut-off of 1.6 x the trendline for healthy controls.
