Selection factors in the choice of immunoassay technology: implementing technology in the new era

Centralized Laboratory Services, Inc. is a large, freestanding laboratory that underwent a major equipment reconfiguration for the performance of endocrine/tumor marker/anemia assays (N = 15) in August 1995. Before the transition these assays were done on six instruments, none of which were computer interfaced. All assays were subsequently consolidated on four ACS-180+ instruments (Chiron Diagnostics, Norwood, MA), which were interfaced to our laboratory information system (Cerner Corp, Kansas City, MO). Our experience suggests that significant increases in productivity and reductions in cost are possible through instrument upgrades. Both laboratory-specific and analytical system-specific factors were found to be important in the optimal selection of immunoassay technology. As laboratorians necessarily adjust to changing economic and organizational circumstances and are compelled to "do more with less," technology assessment will become an increasingly important function for senior laboratory management.
