What does differential diagnosis refer to?

Differential diagnosis refers specifically to the process of identifying a list of potential diseases or conditions that could be causing a patient's symptoms. It is an essential part of clinical assessment where a healthcare provider evaluates the symptoms presented by a patient and considers various possible underlying medical conditions. This list of possibilities helps in narrowing down the true cause of the symptoms through further evaluation, testing, and clinical judgment.

This process is critical in ensuring that the correct diagnosis is made, as many diseases may present with similar symptoms. By systematically considering and ruling out potential causes, healthcare providers can arrive at a more accurate final diagnosis, which is vital for determining the appropriate treatment plan for the patient. The importance of differential diagnosis lies in its ability to avoid misdiagnosis and ensure comprehensive patient care.
