Precision Group Allocation for Animal Studies

In GLP toxicology and pharmacology studies, balanced group allocation is critical. Vizenta automatically assigns animals to treatment groups using validated statistical methods, eliminating weight and gender bias at the point of randomization.

  • Automatically balances body weight across all groups
  • Stratifies by sex, age, species, and strain
  • Supports block and stratified randomization per OECD guidelines
  • Assigns animals to dose, recovery, and satellite groups
  • Generates validated animal allocation reports with e-signature

Systematic Bias Elimination for Laboratory Experiments

In cell-based assays, compound screening, and analytical testing, systematic positional bias in plate layouts can skew results. Vizenta randomizes samples, well positions, and analytical sequences to ensure unbiased laboratory outcomes.

  • Randomizes plates, wells, and analytical sequences
  • Eliminates edge and positional effects in multi-well assays
  • Assigns compounds and replicates across batches
  • Tracks sample provenance with full chain-of-custody
  • Supports blinded analysis for objective results
