  - Installation
    Find details on the system requirements for the Biological Assay Package add-on and the steps to install the add-on in your environment.
  - Basic bioassay protocol
    Use Basic bioassay protocol documents to set up a workflow for producing reportable values from multiple independent assay runs. Organize complex methods, retest scenarios, and report several products in a single assay.
  - Combination of assay results
    Use Combination of assay results documents to perform combination calculations for independent assay runs, thus obtaining reportable values for the potency.
  - Equivalence margin development
    Use Equivalence margin development documents to develop and verify test systems based on historic assays and apply these test systems in new development of quantitative response assays.
  - Quantitative response assays
    Use Quantitative response assay documents to calculate the potencies of test samples relative to an established standard. You can also use them to determine absolute potencies based on stock solutions or raw materials.
  - Test system definition
    Use Test system definition documents of the Biological Assay Package to define a collection of suitability tests and corresponding margins for Quantitative response assay documents.
  - Use case: Automate a bioassay workflow
    For some biological assays, determining relative potency within a single run is not sufficient. In these cases, you perform multiple individual assay runs and then combine the resulting data to obtain a more reliable final potency estimate. The challenge is to combine these individual results efficiently and reproducibly, particularly in regulated environments or when preparing for automated workflows.

Test: Root mean square error (RMSE)

Add one or several tests for the root mean square error to your assay. To add the tests as assay suitability tests, add them as children of the Assay suitability tests element. To add the tests as sample suitability tests, add them as children of the Sample suitability tests element.

Important: Test definitions are ignored without notification if you select a type of test that is not valid for the model you use or the scope you select.

To pass the test, the square root of mean square error of the unrestricted regression fit has to be less than or equal to the upper margin set in the test definition.

All

Standard only: Runs the test for the Standard sample.
Test samples only: Runs the test for every Test sample.
Control samples only: Runs the test for every Control sample.
All assay elements: Runs the test for every assay element except Control lines.

Assay element: Runs the test on the data of individual assay elements. Example: If you set the scope of the test to 'Test samples only', the test is evaluated for each individual Test sample.
Assay (without simultaneous regression): Runs the test on the data of individual Test-vs-Standard and Control-vs-Standard comparisons. Example: If you set the scope of the test to 'Test samples only', the test is evaluated for each individual Test-vs-Standard comparison.
Assay (simultaneous regression): Runs the test on the data of the whole assay. Example: If you set the scope of the test to 'Test samples only', the test is evaluated for the whole assay.

Note: If you set the Extent of the test to 'Assay', the test is either evaluated for each Standard-vs-Test sample comparison or the whole assay in the case of simultaneous regression. Therefore, also setting the Assay element type scope to 'Standard only' is not supported.
