How We Build This Report

Primary Source Collection

Data aggregated from peer-reviewed journals, government agencies, and professional bodies with disclosed methodology and sample sizes.

Editorial Curation

Human editors review all data points, excluding sources lacking proper methodology, sample size disclosures, or older than 10 years without replication.

AI-Powered Verification

Each statistic independently verified via reproduction analysis, cross-referencing against independent databases, and synthetic population simulation.

Human Cross-Check

Final human editorial review of all AI-verified statistics. Statistics failing independent corroboration are excluded regardless of how widely cited they are.

Statistics that could not be independently verified are excluded regardless of how widely cited they are elsewhere.

Diagnosis and Testing Interpretation

While the array of strep diagnostics might feel like a medical game show—with tests ranging from the rapid but sometimes deceptive contestant (RADT) to the slow but reliable grand prize (culture), all judged by a panel of clinical criteria—the clear takeaway is that no single clue is perfect, but stacking them wisely gets you much closer to the truth without overusing antibiotics.
