A voluntary collective of specialists applying R programming and statistical tools to quality management in Brazilian clinical laboratories.
The LabR Group bridges the gap between statistical science and clinical practice — building free, open-source tools that help Brazilian laboratories achieve excellence through data.
Advanced SQC methods implemented in R — Westgard rules, sigma metrics, OPSpecs charts and beyond.
Automated reference interval computation with the LabRI suite — robust, partitioned, and IFCC-compliant.
Applying clustering, classification and AI to diagnostic problems — from delta checks to result plausibility.
Bias, precision, linearity and measurement uncertainty workflows following CLSI and ISO 15189 standards.
A growing book, blog, presentations and YouTube tutorials — all freely available in Portuguese and English.
All code published on GitHub. Every tool, every analysis, every method is transparent and reproducible.
Subscribe to our YouTube channel for tutorials, project walkthroughs and quality management deep-dives.
Our flagship toolset for computing reference intervals — available as a Shiny app and an AI-powered chatbot.
