diagnostischen

Diagnostisch is a German adjective derived from Diagnose and refers to procedures, criteria, or tools used to determine a condition or state. The form diagnostischen is the declined variant used in several grammatical contexts, such as the plural nominative and accusative after a definite article (die diagnostischen Methoden) or the dative plural (den diagnostischen Methoden).

In medical contexts, diagnostisch describes activities within the broader field of Diagnostik, the systematic process of diagnosing diseases or injuries. Common phrases include diagnostische Tests, diagnostische Verfahren, diagnostische Kriterien, and diagnostische Bildgebung. The noun Diagnostik denotes the overall practice and methodology of diagnosis.

Beyond medicine, diagnostisch appears in engineering, information technology, and other technical fields to denote diagnostic capabilities or analyses. Examples include diagnostische Systeme, diagnostische Fehleranalyse, diagnostische Tools, and diagnostische Auswertungen. In these areas, the term often refers to methods for identifying faults, monitoring states, or assessing performance.

Usage notes emphasize that diagnostisch typically precedes nouns and follows standard German adjective declension rules. The ending -en commonly appears in plural phrases (die diagnostischen Methoden, den diagnostischen Parametern); other endings occur in singular forms depending on gender and article. The term is closely related to the noun Diagnostik and to the noun Diagnose, which denote the process and the result of the determination, respectively.

Originating from Greek roots through Latin and German, diagnostisch has become a standard descriptor in technical and clinical language for anything related to diagnosis. See also Diagnostik, Diagnose.
