Diagnosti

Diagnosti is not a standard term in English and may appear as a truncated form or in non-English contexts where the root of diagnosis is used in longer words. In practice, the concept most closely associated with diagnosti is diagnosis, the process of identifying the nature of a disease or condition based on a patient’s history, symptoms, examination findings, and test results. Medical diagnosis often involves formulating a differential diagnosis — a ranked list of possible conditions that could explain the observed information — and refining it through additional investigations such as laboratory tests, imaging, or procedures.

The field that studies and supports this process is commonly referred to as diagnostics or diagnostic medicine. Diagnostics encompasses the tools, tests, and methodologies used to detect health issues, monitor disease progression, assess prognosis, and evaluate responses to treatment. This includes laboratory assays, radiologic imaging, genetic testing, and clinical decision rules, as well as point-of-care testing and telemedicine workflows.

In other domains, diagnostics also refers to methods for assessing system health and performance, such as computer hardware and software diagnostics, automotive diagnostic tools, and industrial process monitoring. These applications share a core aim with medical diagnosis: to identify faults or abnormalities, determine likely causes, and guide corrective action.

Etymology traces diagnostic terms to Greek roots meaning to distinguish or know through examination. See also diagnosis, diagnostic, and diagnostics.
