Now let us examine each of the components of the M.A.A.R.I.E. framework beginning with the Method component.

METHOD

Method: Purpose of Testing2

Testing can be seen as the collection of information to assist in decision making. When looked at this way, much of what is done in health care can be regarded as testing, from obtaining information from the history and physical examination, to making decisions based on the prognosis of a disease. To understand the use of a test, we need to appreciate the multiple purposes for which a test may be used. The same test may at times be used for more than one purpose, but its performance often depends on the specific purpose for which it is being used.

Testing may be used for at least the following purposes:

Testing for risk factors: Testing for factor(s) or other disease(s) that increase the risk of the disease of interest

Screening test: Testing patients without symptoms for a particular disease

Diagnostic testing: Testing patients with symptoms for the presence of a particular disease

Testing for prognosis: Testing to predict the outcome of disease

Testing for causation: Testing to establish the relationship between symptoms and disease

Testing for response: Testing response to treatment including testing for adverse events associated with treatment
