From: A comparative study of blood endotoxin detection in haemodialysis patients
Population | Assay | Slope | Proportional error (%) | Y-intercept (constant error) [EU/mL] | Correlation coefficient |
|---|---|---|---|---|---|
HD (n = 5) | Turbidimetric | 1.042 [0.927–1.157] | 4.2 | 0.016 [−0.130–0.162] | 0.962 |
Chromogenic | 0.678 [0.625–0.731] | 32.2 | −0.027 [−0.094–0.041] | 0.939 | |
Healthy (n = 5) | Turbidimetric | 0.882 [0.821–0.943] | 11.8 | 0.067 [−0.011–0.145] | 0.954 |
Chromogenic | 0.41 [0.320–0.500] | 59 | −0.011 [−0.128–0.102] | 0.922 |
