While the lab you wish to delete is displayed (use the record navigation buttons in the lower left corner if required), press the Delete Lab button.. A confirmation message will appear asking you to confirm deletion. Press Yes to delete.
Caution! Once you have scheduled samples to use analysis packages from this lab, by deleting the lab you will affect both samples that have already been scheduled and/or collected as well as future samples requiring this package. A notification of this will appear if you try to delete a lab that has already been used by SiteFX.
