Traceability - the key to accurate laboratory results for patients

The results from laboratory medicine tests influence a high percentage of all clinical decisions. The Joint Committee for Traceability in Laboratory Medicine (JCTLM) is working with many global partners to reduce between-method variability. The production and adoption of reference materials, reference methods and the establishment of reference laboratories are drivers for accurate patient results. JCTLM maintains a database of these higher order materials and methods. JCTLM also provides news and educational resources to increase an understanding of the importance of traceability in laboratory medicine.
