What is a BQ score?
A bias quantification (BQ) score provides a numerical value for the level of bias observed in a PreAmp reaction. It is based
on comparing the theoretical difference between a sample with and one without PreAmp compared to the observed (actual)
difference between a sample with and without PreAmp. Zero indicates no bias, and the farther from zero the BQ score
becomes, the greater the bias introduced.
