  - 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.
    - Combination calculation methods
      The combination calculation method determines the weighting of the results from the independent assay runs during the calculation process.
    - Basic concepts
      Combination of assay results documents use a set of concepts you should be familiar with when working with this document type.
    - Compendial guidance
      The methods and procedures provided by the Combination of assay results document type are based on use cases and requirements from literature.
  - 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.

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.

About this document type

Combination of assay results documents support you in evaluating assay consistency across mutliple runs. They let you combine independent potency estimates to improve the precision of the result and account for variations such as variability in cells or different operators. You can set up combination calculations for quantitative response and dichotomous assays.

These documents are commonly used in routine testing and trending scenarios, or as part of assay validation workflows.

Tip: You can identify documents of this type by the

Document structure

Each Combination of assay results document has three default sections, that is, Documentation, Setup, and Analysis, plus one or more optional Comment sections.

Figure 1. Sections of a Combination of assay results document displayed in the Content editor


Section	Description
Documentation	Add groups. A group usually corresponds to a reportable value. You can use groups to add information with which to identify the substance to the report.
Setup	Adjust the dataset structure used to summarize reportable values generated by the Combination of assay results document.
Analysis	Specify the combination type, compendial guidance, potency type, logarithm type, and the suitability tests to be used in calculations.
Comment	Add extra information to your assay. The PDF reports display the comments you add on the first page. You can use a simplified Wiki notation for the text. For details on the Wiki notation, see the Simplified Wiki notation topic.
