Diagnózist

Diagnózist is the Hungarian term for diagnosis, the medical determination of the nature of a patient’s illness or condition. It is the conclusion reached by a clinician after evaluating symptoms, history, examination findings, and test results. A diagnosis can be provisional or definitive and may be refined as new information becomes available. In practice, doctors often formulate a working or differential diagnosis, listing several possible conditions that could explain the presenting signs and deciding which tests or observations are needed to confirm the most likely possibility.

The diagnostic process combines data gathering (history taking, physical examination, laboratory tests, imaging, and other procedures), clinical reasoning, and, when appropriate, consultation with specialists. The accuracy of a diagnosis depends on the quality of information, the prevalence of diseases in the population, and the performance of diagnostic tests, which have sensitivity and specificity characteristics.

Types of diagnosis include etiologic diagnosis (identifying the cause), descriptive or syndromic diagnosis (grouping symptoms into a syndrome), and differential diagnosis (comparison among possible diseases). A final diagnosis may follow a provisional or working diagnosis as test results clarify the condition. Documentation and communication with the patient are essential parts of the process.

Importance and impact: a diagnosis guides treatment, prognosis, and management decisions, and informs patient counseling and public health measures. Misdiagnosis carries risks of unnecessary or inadequate therapy.

Historically, diagnostic practice has evolved from symptom-based judgments to evidence-based methods, aided by laboratory testing, imaging, and standardized criteria and classification systems used in medicine and allied health fields.
