Primary/Backup rules for multiple reagent containers

The following rules are used to determine the Primary reagent container when multiple reagent containers are loaded for the same method. Deselected or empty reagent containers are not included in the ranking.

1. Reagent is calibrated.

2. The reagent container with the shortest Days Remaining value is used first. It is Primary and all other containers are Backup.

3. If all reagent containers have the same Days Remaining, the container with the nearest Expiration Date is Primary.

4. If all reagent containers have the same Days Remaining and Expiration Date, the container with the lowest # Tests is Primary.

5. If all reagent containers have the same Days Remaining, Expiration Date, and # Tests, the container with the lowest Posi. # is Primary.
