What is prognostic method?

Prognosis–the prediction of the course and outcome of disease processes–plays an important role in patient management tasks like diagnosis and treatment planning. As a result, prognostic models form an integral part of a number of systems supporting these tasks.

What is prognostic test example?

For example, blood pressure and cholesterol levels are both biomarkers that tell us something about the state of someone’s health. In prognostic tests for Crohn’s disease and ulcerative colitis the biomarkers may help predict future events in your disease.

Since time is of the essence: diagnosis is used to identify a present disease, illness, problem, etc., by examination and observation (of signs and symptoms); prognosis refers to predicting the course of the diagnosed disease, illness, problem, etc., and determining treatment and outcome.
