Intraday and interday accuracy and precision for GHB in rat plasma

Each measured concentration is the mean of triplicate measurements. The analysis was performed over 3 days.

	Nominal Concentration	Measured Concentration	S.D.	Precision	Accuracy
	μg/ml			CV%	%
Intraday	10	10.8	0.12	1.07	107.7
	125	121	4.36	3.60	96.8
	400	375	6.93	1.85	93.7
Interday	10	10.5	0.32	3.05	105.2
	125	118	2.96	2.50	94.9
	400	368	6.38	1.73	92.0

CV, coefficient of variation.
