Calculate 2SD Limits using Mean and 1SD
Helpful when published confidence limits are 3SD
Facilitates set-up of QC programs that require 2SD limits, such as the Daily QC Assessment Templates SLT_105, SLT_400
Simplifies Comparison of Insert Limits to Peer Limits, or Limits derived from user parallel testing
