Aurora Stats provides quick efficient statistical evaluation of control data. It can support direct analyzer data input or manual entry. Standard precision Levey-Jennings with Westguard rules are assignable. Custom criteria can also be established. This package was also initially released as an integrated component of a laboratory instrument and then as a QC compiler for similar instruments. Aurora Stats capabilities have been expanded to receive data from a wide variety of instruments and to allow for manual entry of QC data where an electronic transfer is not available.
