Precision and accuracy of the assay method for etravirine in rat plasma

	Theoretical concentration
	Low (2.5 ng/mL)	Medium (25 ng/mL)	High (50 ng/mL)
Intra-day (n=6)
Mean	2.52	25.73	50.07
SD	0.06	0.31	0.19
Precision (CV%)	2.48	3.6	0.37
Accuracy (% bias)	0.93	0.24	0.13
Inter-day (n=18)
Mean	2.52	25.0	50.0
SD	0.06	0.44	0.44
Precision (CV%)	2.54	1.7	0.89
Accuracy (% bias)	0.8	3.35	0.01

CV% = (standard deviation/mean)×100.

%bias = [(measured concentration − theoretical concentration)/theoreti
