diagnosis
The identification and naming of an illness by a doctor based on symptoms and examinations.
Nach mehreren Tests konnte der Arzt endlich eine klare Diagnose stellen.
After several tests, the doctor was finally able to make a clear diagnosis.
The most important verb used with 'Diagnose' (diagnosis) is 'stellen' (to make). Doctors or technicians 'stellen eine Diagnose' (make a diagnosis). It is a common mistake to use 'machen' instead.
Der Spezialist hat eine schnelle Diagnose gestellt.
The specialist made a quick diagnosis.
The context tells you whether the medical or technical meaning is intended. Words like 'Arzt' (doctor), 'Krankheit' (illness), or 'Symptome' (symptoms) point to the medical meaning. Words like 'Techniker' (technician), 'Computer' (computer), or 'Fehler' (error/fault) point to technical analysis.
Die Diagnose des Arztes war eine schwere Grippe.
The doctor's diagnosis was a severe flu.
In a medical context, you can also 'bekommen' (get) or 'erhalten' (receive) a diagnosis. The result is often introduced with 'die Diagnose lautet ...' (the diagnosis is ...).
Gestern habe ich die endgültige Diagnose vom Arzt bekommen.
Yesterday I got the final diagnosis from the doctor.
test
'der Test' and 'die Diagnose' often appear in the same situation, but they do not mean the same thing. A 'Test' is an examination or testing procedure. A 'Diagnose' is the result or expert assessment afterward, for example what illness someone has or why a technical problem occurs. The words can be confused because a test can lead to a diagnosis. Memory aid: the 'Test' provides information; the 'Diagnose' names the cause or illness.
Nach der Untersuchung stellt die Ärztin eine klare Diagnose.
After the examination, the doctor makes a clear diagnosis.
Nach dem Essen macht sie zu Hause einen Test, weil sie Fieber hat.
After eating, she takes a test at home because she has a fever.
