Test economy

The test economy primarily examines the cost-benefit ratio between the effort of a test procedure and the benefit of the test result. It also clarifies whether the information obtained from the method is really needed for the diagnostic decision.

If a test is to be good from an economic point of view, the framework conditions and all costs incurred must be in a favorable relationship to the benefit. A test is particularly economical if the costs (material, personnel, etc.) are low in preparation, implementation and evaluation. Often, the test economy is used as a decision criterion for or against a procedure, since compliance with this quality criterion creates short-term financial added value.
