Diagnostiskt

Diagnostiskt is an adjective used in Swedish (and to some extent in other Nordic languages) meaning relating to diagnosis or techniques used to determine a condition. It is used to describe tests, tools, procedures, or criteria that are intended to identify or establish diseases, states, or problems. For example, ett diagnostiskt test (a diagnostic test) or diagnostiska verktyg (diagnostic tools).

In Swedish, diagnostiskt is the neuter singular form of the adjective diagnostisk, and it appears before neuter nouns. The form changes with gender and number for other noun classes, for instance diagnostisk arbetsmetod or diagnostiska tester. The term is commonly found in medical, psychological, veterinary, and technical contexts, as well as in information technology and automotive diagnostics.

Etymology traces diagnostiskt to the Greek diagnostikos, through Latin diagnosticus, with the Swedish suffix -isk that marks adjectives. The root shares cognates in other languages, such as diagnostic (English) or diagnostik (the field or study of diagnosis).

Usage and scope: diagnostiskt describes anything designed to aid diagnosis, including tests, imaging procedures, assessment tools, and criteria used to determine a condition. It does not denote a final conclusion itself but the process or instrument aimed at identifying an issue. Related terms include diagnostik (the science or discipline of diagnosis), diagnos (diagnosis), and diagnostiker (a diagnostician).
