White Horse Laboratories Week 24 Counterfeit Detection Report

White Horse Laboratories Week 24 Counterfeit Detection ReportMy apologies for the delay from Week 23 to Week 24, and you’re going to get weeks 24 through 26 in rather rapid succession now that I’m back from a short break and some exceptionally long days preparing for, and then catching up, from said break.

We saw a broad reversal of fortunes in Week 24 with Testing rates recovering 15 points back to a 72% lot pass rate but Inspection acceptance rates dropping back down 21 points to 65% when compared to Week 23 figures. Still, the improvement in Testing pass rates lead shipping volumes to a 200% recovery.
