Summary

Medical diagnosis is the process of determining which disease or condition may explain a person's symptoms and signs. It helps clinicians make decisions about treatment and prognosis, but it is often uncertain and may develop as new information becomes available.

A medical diagnosis is a reasoned identification or classification of a person's condition. In medical contexts, the word diagnosis usually refers both to the conclusion and, depending on context, the process used to reach it. The plural is diagnoses; the verb is to diagnose, and a person who makes a diagnosis is a diagnostician.

All flashcards

What is medical diagnosis?
It is the process and resulting opinion used to identify or classify a condition from available information, supporting decisions about care and prognosis.
What is a nonspecific finding?
A finding that can occur in multiple conditions and therefore does not, by itself, identify one particular cause. Skin redness is one example.
What does pathognomonic mean?
It describes a sign or symptom, or a combination of findings, that is strongly characteristic of a particular condition and can make diagnosis easier.
What is etiology?
Etiology is the cause or origin of a disease or condition. A diagnosis may identify a condition without fully establishing its etiology.
What can prompt diagnostic assessment?
A patient complaint, a departure from normal function, an observation made during an encounter, or an incidental finding suggesting another condition can prompt assessment.

Quiz questions

  1. What is the main purpose of a medical diagnosis?Answer: To classify a condition and guide care decisions.
  2. How does a symptom differ from a sign?Answer: A symptom is experienced; a sign is observable.
  3. Why may skin redness alone be insufficient to identify a disease?Answer: Redness is nonspecific and occurs in many disorders.
  4. A clinician notices an unusual gait before the patient has described a complaint. What does this illustrate?Answer: An observed gait abnormality can prompt assessment.
  5. A patient does not improve with treatment that usually works for the diagnosed condition. What is an appropriate implication?Answer: Reconsider the diagnosis and assess alternatives.
