Solving Complexities in Algae Growth Inhibition Test Analysis
A single OECD TG 201 “Algae Growth Inhibition Test” study requires entirely different mathematical approaches: basic arithmetic for Test Validation, non-linear regression for ECx, and complex decision trees for Hypothesis Testing. General statistical software forces you to jump between Excel and multiple programs to piece these together.
Old Way (Fragmented)
Manual calculation in Excel (Validation)
Export to Software A (EC50)
Export to Software B (NOEC/LOEC assumption checks)
Time-consuming and Error-prone.
ToxGenie Way (Integrated)
Upload raw biomass data
ToxGenie’s engine autonomously executes the validation, regression, and hypothesis testing in parallel
Fully documented and publication-ready in seconds.
100% Automated Analysis Flow
From Raw Biomass to Final Endpoints in One Click
OECD TG 201 “Algae Growth Inhibition Test” strictly requires endpoint calculations for both the average growth rate and the yield. Instead of running your analysis twice, ToxGenie’s architecture processes both biological endpoints simultaneously from a single raw data upload, halving your processing time while maintaining absolute statistical rigor.
STEP 1
Automated Test Validation (Limit & Definitive)
The system automatically calculates and verifies the OECD TG 201 acceptance criteria in the background, including the control growth factor (>16) and the coefficient of variation (CV) for both section-by-section and average growth rates.
STEP 2
Dual Point Estimation (EC10, EC20, EC50 + 95% CI)
ToxGenie simultaneously executes Non-Linear Regression for both Average Growth Rate and Yield, automatically determining the best-fit model to calculate precise ECx values and robust 95% Confidence Intervals.
STEP 3
Auto-Determined NOEC & LOEC
The engine autonomously runs normality and homogeneity assessments on your dose groups. It then seamlessly routes the data to the correct parametric (e.g., Dunnett’s) or non-parametric (e.g., Steel’s Many-One) test to determine defensible NOEC and LOEC values.
STEP 4
Limit Test Analysis
For single-concentration setups, ToxGenie verifies significant growth inhibition using robust Two-Group Comparisons, perfectly tailored for both Growth Rate and Yield evaluations.
Perfect Sweden Water Research Alignment. Total Trust.
We processed identical toxicity datasets from official Sweden Water Research, and ToxGenie’s outcomes matched perfectly. This proven consistency ensures you can fully trust ToxGenie with your most critical scientific data.
Validity of the Test
Auto-Calculation & Validation
ToxGenie automatically calculates the ‘Validity of the Test’ for OECD TG 201 and determines whether it meets the required criteria.
Proven Accuracy and Reliability
ToxGenie yields results highly consistent with established methods, ensuring exceptional accuracy and reliability in its automated analysis.
EC10, EC20, and EC50 for Average Growth Rate

STATISTICAL DOCUMENTATION
Generate Publication-Ready Statistical Reports.
ToxGenie eliminates the “Black Box.” Generate comprehensive statistical reports that include the exact rationale for model selection.
User-Selected Formats
Output your final report in either PDF (for secure, audit-ready archiving) or MS Word, depending on your current needs.
Manuscript & GLP Ready
Highly requested by our beta testers. Export to MS Word to seamlessly copy and paste the statistical rationale, tables, and graphs directly into your GLP Final Reports or academic papers.
Defensible Rationale
Every report explicitly justifies why a specific statistical method was applied, providing you with perfect defensibility for regulatory submissions (OECD, EPA).
Why is ToxGenie better than using standard statistical software (like SPSS or R) for OECD 201 "algae Growth Inhibition Test"?
Standard software requires you to manually perform test validations in Excel, write separate scripts for non-linear regression (ECx), and manually check assumptions for ANOVA/Dunnett’s (NOEC). ToxGenie is the only platform that integrates all these distinct methodologies into a single, automated engine specifically coded for the OECD TG 201 guidelines, reducing analysis time by over 70%.
How does the system handle the Test Validity Criteria?
Upon uploading your raw biomass or cell count data, the engine first calculates the control group’s growth factor and the coefficients of variation (CV). It explicitly flags whether the assay meets the strict validity requirements mandated by the OECD before proceeding to endpoint calculations.
Does the software generate plots for the manuscript?
Yes. Alongside the comprehensive statistical rationale, ToxGenie automatically generates publication-ready dose-response curves and growth curve plots for both Average Growth Rate and Yield, which can be directly exported for your manuscript.
