This topic describes options for managing assay designs. Assay designs can be defined in a local container, or shared from a project or sitewide from the Shared
project. Be aware that editing a design shared in other locations will change it for all users. Another alternative is to edit a copy of the design.
Manage an Existing Assay Design
Open the list of currently defined assays by selecting (Admin) > Manage Assays
. Click on the name of any assay to open the runs page. The Manage Assay Design
menu provides the following options:
- Edit assay design: Add, delete, or change properties or structure. Note that all current users of the assay design, including those in subfolders, will be impacted by these changes.
- Copy assay design: This option lets you create a new assay design based on the current one. Changes to the copy do not affect the original design or runs that use it.
- Delete assay design: This option will delete the current design as well as all runs that used it. You will see a list of what would be deleted and have a chance to confirm or cancel this action.
- Export assay design: The design will be exported to a XAR file you can import elsewhere. See Export/Import Assay Design.
- Set default values: Described below.
- Create QC trend report: Create a QC trend report to track metrics relevant to your instrument. Learn more in this topic: Quality Control Trend Reports.
Set Default Values
Fields in an assay design can support defining default values using the field editor
. Defaults can be of several types: last entered, editable default, and a fixed value.
Values for editable and fixed value properties are then set using the Set Default Values
option on the Manage Assay Design
menu. The assay design may be then be inherited in subfolders, which may override these parent defaults if needed using the Set Default Values
option in the other container. These folder defaults will, in turn, be inherited by sub-folders that do not specify their own defaults.
You can set defaults for:
- Batch fields
- Run fields
- Properties specific to the assay type. For example, for an Luminex assay, additional items would include "analyte" and "Excel run file" properties.
Assay Data Auditing and Tracking Changes
Some assays, like the General assay type, allow you to make run and data rows editable individually. Editability at the run or result level is enabled in the assay design by an administrator. Any edits are audited, with values before and after the change being captured. See the audit log's Assay/Experiment events
. Upon deleting assay data, the audit log records that a deletion has occurred, but does not record what data was deleted.
Some assays like Luminex and the General type allow you to upload a replacement copy
of a file/run. This process is called "re-import" of assay data. The server retains the previous copy and the new one, allowing you to review any differences.
See the Assay Feature Matrix
for details on which assay support editable runs/results and re-import.
