- Reference L = analyte concentration limit defined by the testing laboratory, reference A = analyte concentration limit defined by Oh and Brown (2003), reference B = analyte concentration limit defined by Bates and Lewis (2012), Quadrant = chart quadrant:
, Count = number of concurrent analyte pair concentration results within each quadrant
, Count = number of concurrent analyte pair concentration results within each quadrant
