Coefficient of variation of turbidimetric and chromogenic assay in pooled uremic and non-uremic plasma

Concentration of endotoxin spike (EU/mL)		CV - onset reaction time (%)		CV - EU/ml (%)
		0.05	0.5	0.05	0.5
Population	Assay
HD (n = 2)	Turbidimetric	4.6	2.5	24.1	8.9
	Chromogenic	2.4	3.8	Undefined	25.8
Healthy (n = 2)	Turbidimetric	2.8	1.3	9.3	4.5
	Chromogenic	5.4	4.6	Undefined	26.5

In samples where spike recovery was 0 %, CV was undefined. CV coefficient of variation, EU/mL endotoxin units per millilitre
