Sample	Calibrator (ng/ml)	Range	CVa (%)
Intra-assay
Low	50	53.0 ± 3.36	6.33
Medium	100	93.9 ± 3.08	4.04
High	200	238.5 ± 12.5	5.25
Inter-Assay
Low	50	51.9 ± 2.59	5.0
Medium	100	100.3 ± 8.02	8.01
High	200	224.6 ± 14.68	6.54

Range values are the mean and standard deviation from five independent experiments

^aCV stands for co-efficient of variance
