Abstract:Objectives
Our objective was to maintain low interlaboratory variation and bias in international normalized ratio (INR) results following a network change in instrumentation and reagents, using a process of ongoing standardization and harmonization.
Methods
Network-wide standardization to new common instrument and reagent platforms followed by network-wide application of a simple novel process of verification of international… Show more
