Evidence stage
DeploymentAn employer has put it into production. Can move the baseline — weighted by scale and how similar the setting is.
Tasks this bears on
Handling the specimen
Receiving, spinning, aliquoting, and dealing with the sample that arrived clotted, short, unlabelled or at the wrong temperature.

Where this applies
A peer-reviewed study of the chemistry and immunoassay laboratory at a university hospital in Seoul, comparing December 2018 (partial automation, 1,151,501 tests) with December 2019 (full automation, 1,182,419 tests). It reports that the weighted tube touch moment — the average number of manual operations needed to process a sample from registration to archiving — improved by 77.6%, and that actual full-time equivalents in 2020 were reduced by 2.5 to 3.0. The authors declare no conflicts; the staffing figures for later years in the paper are projections and are not used here.
What this means
Handling the specimen is where total lab automation bites hardest: the number of times a person touches a tube fell by about three quarters, and a few full-time posts went with it. What stays is the sample the line rejects.
What it does not yet show
One hospital lab and one before-and-after comparison; it does not show what happened to rejected or problem specimens, and later staffing figures are projections.
What you can check
Open Kim et al., Ann Lab Med 2022;42(1):89–95 on PubMed Central and find "improved by 77.6%".
Does it change the assessment?
No. The impact index is never moved by a single event. Nor did this record change a layer: all 1 linked judgement above already rested on earlier evidence. This one adds to them.
