Recent trends in immunoassay automation have been concentrated in two basic
directions. The first trend, which started in the late 1980s, focused on c
onsolidating the immunoassay with routine clinical chemistry analysis into
a single analyzer. The second, and most recent, trend in immunoassay automa
tion has focused on pre-analytical and post-analytical steps in the analyti
cal process. Specimen transportation is becoming automated from sample pick
up to delivery and directly into the analyzer. Following the transportation
process, pre-analytical automation is providing hands-free centrifugation,
decapping, and aliquotting in automatically relabeled tubes. New levels of
computer sophistication are providing administrative oversight of all thes
e automated activities, The resulting efficiencies can reduce current labor
costs by as much as 50%.
