White Horse Laboratories Week 25 Counterfeit Detection Report

White Horse Laboratories Week 25 Counterfeit Detection ReportWeek 24 should be fairly fresh in your memory as it was issued the day prior to Week 25.

Week 25 saw a welcomed recovery in acceptance rates following inspection, climbing 15 points from Week 24 to 80% in Week 25. Similarly, lot pass rates on electrical testing climbed 11 points to 83% in Week 25 with volumes gaining 14% on the improved yields.

Bear in mind that not all lots go through both inspection analysis and electrical testing – many lots are rejected after inspection and never make it to testing while other lots are tested only depending on the buyer’s requirements.

Inspection: 80% accept      Testing: 83% passed
