What is the difference between the diagnosis and prognosis of a disease?

Prognosis vs. Diagnosis. People often confuse the terms prognosis and diagnosis. The difference between the two is that while a prognosis is a guess as to the outcome of treatment, a diagnosis is actually identifying the problem and giving it a name, such as depression or obsessive-compulsive disorder.

What is the difference between a diagnostic test and a prognostic test?

Typically patients are classified as diagnostic test positive or negative to estimate the test’s accuracy as sensitivity (true postive fraction) and specificity (true negative fraction). In contrast, a prognostic test is used to predict a patient’s likelihood of developing a disease or experiencing a medical event.

What is prognosis disease?
