"La concentrazione delle endotossine batteriche utilizzate durante lo studio, deve risultare ***ridotta di 3 valori in scala logaritmica***, secondo le procedure operative approvate dal reparto di Controllo Qualità."

I realise that we are talking about logarithmic scale values here, however I am at a loss as to how to express the part in asterisks in mathematical-speak. I am sure the answer will reveal itself to be straightforward, but right now I am somewhat in the dark with this.

Thanks in advance for any input!

Units? I think they are saying that the concentration must decrease by three units on a log scale. If this is referred to a base 10 logs scale, it would mean a decrease of three orders of magnitude (a factor of 1,000).
