Prognosis vs. Diagnosis: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 30, 2023
Diagnosis is identifying a disease from its symptoms; prognosis is the likely outcome of that disease.
Key Differences
Let's understand that prognosis and diagnosis are terms commonly used in medicine. A diagnosis is what healthcare professionals use to identify a disease or condition based on signs and symptoms. On the other hand, prognosis refers to the likely course and outcome of the diagnosed disease.

Diagnosis is derived from the Greek word "diagnōsis," meaning "discernment" or "distinguishing." Diagnosis is crucial for determining the appropriate treatment for a patient. Conversely, prognosis comes from the Greek word "prognōsis," meaning "foreknowledge." Prognosis gives an estimation of the likely progression and outcome of the disease.

Diagnosis is a critical step in the medical process. It involves a thorough examination and often requires various tests and procedures. A correct diagnosis is essential for effective treatment. In contrast, prognosis often depends on factors such as age, overall health, and how well the disease responds to treatment.

It's important to note that prognosis can be uncertain and may change as more information becomes available. While diagnosis is usually definitive, prognosis is an educated guess based on statistics and trends. Both are essential components of the healthcare process, and they work hand-in-hand to provide the best possible care for patients.
