The interpretation of Statistical Process Control results is supported by the use of several Unity Real Time features, including two prospective review options:

• Autoverification is possible with Unity Real Time through a bi-directional interface that communicates rule evaluations to other systems.
• Laboratories may also use Unity Real Times Bench Review for run-time analysis and Supervisor Review for periodic supervisory data analysis.

Bench and Supervisor Review

Unity Real Time displays all pending results by automatically refreshing displays for both prospective and supervisory review. Bench Review displays all the pending results for a selected range of tests for prospective review. Supervisor Review displays all pending results for periodic supervisory review.

Both displays are color-coded to indicate rule violations (yellow for warnings and red for rejections) to facilitate the identification of problems and improve laboratory workflow. Users can link to Levey-Jennings charts or the complete data history on any test for troubleshooting. Both levels of review are recorded, along with any documented corrective actions, in a local report. This report assists laboratories in meeting the requirements of regulatory agencies to document quality control data review.

Local Charts and Reports

Unity Real Time offers several charts and reports to interpret quality control data, including:

• Levey-Jennings (single) Chart
  Levey-Jennings charts plot a set of data points against a mean and 3 standard deviation (SD) range. Unity Real Time users have the option to plot against their fixed mean and SD, floating (cumulative) mean and SD, the mean and 3 SD range of another instrument in the lab or against the consensus group dat
