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 2006-09/S1 ; RH 2006-10/S1 ; RH 2007-03/S3 ; RH 2008-05/S2 ; RH 2010-01/S1 ; RH 2011-05/S2
