Peer Group Statistics (Table 1)

Monthly

			CI (Lot No.: TPC1502AC)										CII (Lot No.: TPC1502AD)
UnitID	Reagent Kit (Code)	Unit	Target	Mean	n for Mean	SD	CV (%)	TE (%)	TEa (%)	σ		Target	Mean	n for Mean	SD	CV (%)	TE (%)	TEa (%)	σ
NS004	9	uU/mL blood	6.0	6.4	15	0.47	7.3	21.4	10	0.5		25.2	26.5	15	2.07	7.8	20.8	10	0.6

Bias (%) = [ (│Mean - Target│) / Target ] x 100%
TE：Total Error(%) = Bias (%) + 2 × CV (%)
σ (Sigma) = [TEa% - Bias (%)] / CV (%)
