Consensus Groups

Westgard Advisor™ online uses the consensus groups from the Unity™ Interlaboratory Program to calculate performance estimates.

Note: Westgard Advisor™ online will not be able to generate rules for a test if there are not any statistics available for the selected consensus group.

The following consensus groups are available:

• Peer group (most specific)
• The Peer consensus group is the ideal group for comparison. It is composed of all laboratories using the same instrument, lot number, level, reagent, analytical method, units, and temperature of a test.
• Method group (next specific)
• Choose the Method consensus group when there is an insufficent number of laboratories in the Peer group. It is composed of all laboratories using the same lot number, level, analytical method, units, and temperature of a test.
• All Labs group (least specific)

  The All Labs consensus group is composed of data from all laboratories using the same lot number, level, units, and temperature of a test.
