Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

0.97/ 3· Robot exposure index
Scale, basis and source
Each physical task is graded 0–3 by the setting in which robots that have been deployed, sold or demonstrated could do it (0 none · 1 purpose-built robot settings such as a fenced machine cell or a bottling line · 2 structured facilities such as a hospital pharmacy or a container port · 3 unstructured settings such as a private home or a construction site), and the grades are averaged by share of working time
Physical tasks among this occupation's O*NET 29.3 tasks
Anthropic estimated the grades and time shares with Claude Opus 5 using web search, as of 2026.
The robot exposure index is a different measure from the AI exposure figures on this site and cannot be added to or compared with them. It does not measure actual adoption or cost, and 0 also covers occupations with no physical tasks.

Medical and pathology laboratory technicians perform clinical tests on specimens of bodily fluids and tissues in order to obtain information about the health of a patient or cause of death.
Tasks
- (a) conducting chemical analysis of body fluids, including blood, urine and spinal fluid, to determine presence of normal and abnormal components;
- (b) operating, calibrating and maintaining equipment used in quantitative and qualitative analysis, such as spectrophotometers, calorimeters, flame photometers and computer-controlled analysers;
- (c) entering data from analysis of laboratory tests and clinical results into records-keeping systems and reporting results to medical practitioners and other health professionals;
- (d) analysing samples of biological material for chemical content or reaction;
- (e) setting up, cleaning and maintaining laboratory equipment;
- (f) analysing laboratory findings to check the accuracy of the results;
- (g) establishing and monitoring programmes to ensure the accuracy of laboratory results and developing, standardizing, evaluating, and modifying procedures, techniques and tests used in the analysis of specimens;
- (h) obtaining specimens, cultivating, isolating and identifying microorganisms for analysis;

ESCO occupational vocabulary
Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.
- biology technicianESCO 3141.2.3This occupation is narrower
Biology technicians provide technical assistance in researching and analysing the relationship between living organisms and their environment. They use laboratory equipment to examine organic substances such as bodily fluids, medicines, plants and food. They collect and analyse data for experiments, compile reports and maintain laboratory stock.
- cytology screenerESCO 3212.1.2Overlapping, not the same
Cytology screeners examine under a microscope samples of human cells obtained from various body parts such as the female reproductive tract, the lung or gastrointestinal tract, assist in identifying cell abnormality and disease such as cancer or infectious agents under supervision, following the orders of the doctor of medicine.The abnormal cells are being transferred to the pathologist for medical diagnosis. They may also work under the supervision of a biomedical scientist. They do not treat patients or assist in medical treatments.
- medical laboratory assistantESCO 3212.2Overlapping, not the same
Medical laboratory assistants work under supervision of the biomedical scientist and carry out basic laboratory procedures. They work in the pre-analytical handling of samples such as checking the details of specimens received for analysis, maintaining analysers, loading reagents, and packaging specimens. They also perform clerical tasks such as monitoring the stock levels of reagents used in analysis.
- scientific laboratory technicianESCO 3141.2Overlapping, not the same
Scientific laboratory technicians carry out laboratory-based research, analysis and testing and support life science professionals. They sample, test, measure, research and analyse in areas such as biology, biotechnology, environmental science, forensic science and pharmacology. Scientific laboratory technicians also observe and monitor laboratory activities, record test sequences and analyse the results.
