1).		: Outlier (this result has been dropped and was not included in calculation of Mean, SD and CV).
2). Standard Deviation Index (SDI) = (Individual Result - Individual Mean) / Individual SD
3). The reference values were determined by reference method at the QC reference Lab.
4). Survey / Sample No.：RH 2007-03/S2 ; RH 2007-07/S1 ; RH 2007-09/S1 ; RH 2008-03/S2 ; RH 2008-11/S2 ; RH 2009-07/S2 ; RH 2010-03/S2
