Z-factor Differentiator

Regulation: FDA allows for ~15% variability (~20% at LLOQ) to pass clinical trials.


Problem: Pharmaceuticals face an accumulation of variability from multiple sources throughout the course of a clinical trial and the higher the variability, the less percent of batches that pass.


Solution: Dr. Rao Marepalli coined the term “Z-Factor” to differentiate the various sources of variability in a clinical study and convey how Sannova minimizes variability from bioanalysis through high-quality proprietary systems and processes. Please see below for data showing our single digit variability and high percent accuracy.
