workup

Workup refers to a set of procedures undertaken to complete or clarify a process after a primary event, action, or result. The term is used in various professional domains, including medicine, laboratory science, and research, and generally denotes the sequence of steps taken to obtain a final diagnosis, product, or understanding. The objective is to ensure accuracy, safety, and reproducibility, and to transition from preliminary findings to a usable conclusion.

In clinical practice, a diagnostic workup comprises history taking, physical examination, laboratory tests, imaging studies, and sometimes procedures or consultations. The aim is to establish a diagnosis or to narrow the differential diagnosis, inform treatment decisions, and assess prognosis or risk. Workups are tailored to presenting symptoms and may be expedited in acute settings; results must be interpreted in the context of pretest probability and may require repeat testing or specialist input.

In chemical synthesis or laboratory experimentation, a workup describes the post-reaction sequence used to isolate and purify the desired product and to render the mixture safe for handling. Typical steps include quenching reactive components, extracting with solvents, washing and drying, concentrating, and purifying by chromatography or crystallization, followed by structural characterization. The specific workup depends on the reaction's reagents, by-products, and the intended product.

Outside science and medicine, workup may refer to broader information-gathering processes such as due diligence, data collection, or investigative procedures performed to complete a project or inquiry. Across domains, good workups emphasize clear objectives, rigorous methodology, documentation, and safety.
