Multicentric reference values for some quantities measured with Tina-Quant® reagents systems and RD/Hitachi analysers

Abstract

Ten clinical laboratories in different regions of Spain have shared the search for reference individuals and the production of reference values for quantities concerning ferritin, transferrin, rheumatoid factors, C-reactive protein and antistreptolysin O, using Tina-Quant® reagents systems and RD/Hitachi analysers. All the logistic work has been done in co-operation with the supplier of the reagents and analysers (Roche Diagnostics España, S.L., Barcelona). The reference limits produced in the virtual laboratory are derived from the blend of reference values obtained by each laboratory. The multicentric reference limits were estimated according to the recommendations of the International Federation of Clinical Chemistry. The work done is amodel of co-operationbetween the in vitro diagnostic industry and clinical laboratories for the production of reference values.
