Matrix Study Designs – Recent Trends

• Collaborative Studies • Up to 3 collaborators per site using the same equipment if work is performed  independently • Independent test portions for each collaborator. • Independent analyses performed by each collaborator. • Single matrix must be the most challenging matrix/enrichment combination  from the SLV or PTM study. • 8 replicates per collaborator is acceptable for qualitative studies harmonized  with ISO 16140‐2, but 12 replicates is preferred.
