Overview

Westgard Advisor™ online is an optional feature of Unity Real Time™ online that identifies the tests needing improvement and the tests routinely achieving the required quality. Westgard Advisor™ online uses the following information to recommend statistical process control (SPC) rules, and the number of control samples per run:

• Data for the test
• A selected TE_a
• A selected consensus group

  The consensus group can be a date range of the laboratory's data or a Unity™ Interlaboratory consensus group (Peer, Method, or All Labs).

Using Westgard Advisor™ online, it is possible to generate rules based on different combinations of these selections, display the OPSpecs Chart, and apply the suggested SPC rules.

Westgard Advisor™ online always provides suggestions. However, if a method has poor performance, Westgard Advisor™ online is not able to recommend a set of SPC rules that will solve performance problems. When no multirule meets the quality specification, Westgard Advisor™ online reports a maximum QC condition and recommends all available multirules.

Note: The rules suggested by Westgard Advisor™ online are recommendations only. Conditions in the laboratory may make some rules impossible to use.
