This article will help you understand the different statuses of lots.

When you enter a "Date Opened" you will see this status. Note: "Opened Expiration" does not show a status.

When you enter a "Date in Use" you will see this status.

This status shows that the control/reagent will expire in 3 days. The status will give you a notice and countdown for 7 days before the expiration when an expiration date has been entered.

On the final day of expiration the status will look like this.

Once the control/reagent has expired the status will look like this. You will not see it on the list of lots available unless you uncheck the Hide Expired Lots box as in this example.

When you enter a "Discarded Date" will see this status. When your lot is discarded the Controls/Reagents box for that lot will turn pink.
