      - Regression model
        Select a regression model to accurately quantify endotoxin levels by fitting a curve or a straight line to the assay data of your bioMérieux endotoxin detection assay.
      - Coefficient of variation
        The coefficient of variation (CV) assesses the precision of the assay, indicating how much variation exists between replicate measurements. A lower CV indicates more consistent, precise results, while a higher CV suggests greater variability and less reliability in the measurements.
      - Final activity rounding
        Final activity rounding lets you round the calculated final activity of a sample during an endotoxin detection assay, thus influencing the interpretation of the final values and ensuring consistency and compliance with predefined limits.
      - Gain optimization
        The gain of a plate reader reflects its dynamic range, indicating the level at which reasonable measurements can still be carried out. bioMérieux endotoxin detection assay documents let you define a gain optimization routine, therefore providing the data you need to adjust the signal amplification to maximize dynamic range and ensure the results remain within the instrument's detection limits.
    - Test system
      Set up a test system to prove the validity of your calculation. The bioMérieux endotoxin detection assay document type provides a set of tests that cover, for example, regression model parameters, recovery rate of the positive product control, coefficient of variation, and behavior of the blank control.
  - Templates
    The bioMérieux Endotoxin Detection Assay Package comes equipped with endotoxin detection assay templates, preconfigured with the analytical settings, test system, and assay layout required for the respective assay kit.
  - Use case: Validate a cleaning process for pharmaceutical water
    In the pharmaceutical industry, water is an important resource both in synthesizing and developing products and in cleaning vessels and other types of equipment. Validating the cleaning processes for pharmaceutical water to prevent product contamination is therefore crucial.

Final activity rounding

Final activity rounding lets you round the calculated final activity of a sample during an endotoxin detection assay, thus influencing the interpretation of the final values and ensuring consistency and compliance with predefined limits.

Note: You may need this feature to follow protocol procedures or company regulations. We do not recommend using rounding for comparing the final activity to the endotoxin limit.

Figure 1. Final activity rounding options of a bioMérieux endotoxin detection assay document

Rounding options

Rounded values are compared to the full-precision endotoxin limit. The following options are available:

No rounding
x decimal places (where x is an integer from 0 to 5)

Note: The rounding method 'half away from zero' is used.

Examples

The following table shows rounding examples for the '2 decimal places' option:


Endotoxin status	Final activity (before rounding)	Final activity (after rouding)	Endotoxin limit
Passed because 0.04 < 0.05	0.0425	0.04	0.05
Passed because 0.05 ≥ 0.05	0.04995	0.05	0.05
