Differential diagnosis is a systematic method used in medicine and other diagnostic fields to identify a specific condition from a set of similar possible conditions. This process involves a careful evaluation of a patient's symptoms, medical history, physical examination findings, and diagnostic test results. The goal is to narrow down the possibilities until the most likely diagnosis can be determined.

The process typically begins with a broad list of potential diagnoses that could explain the presenting signs and symptoms. Each potential diagnosis is then considered and evaluated against the available patient information. This involves looking for characteristic features of each condition and ruling out those that do not fit the clinical picture. Factors such as the prevalence of a disease, the patient's risk factors, and the specific combination of symptoms are all taken into account.

Diagnostic tools such as laboratory tests, imaging studies, and biopsies are often employed to further differentiate between the remaining possibilities. The process is iterative, with new information potentially leading to the addition or removal of diagnoses from the list. Ultimately, differential diagnosis helps clinicians arrive at the most accurate and appropriate treatment plan for the patient. It is a crucial skill in clinical practice, ensuring that patients receive the correct diagnosis and therefore the most effective care.
