1. A method of determining whether an evaluation testing method is clinically equivalent to a reference testing method, comprising the steps of: storing results from a reference testing method and an evaluation testing method in a memory; determining, with a processor, a level of variance based on the results obtained using the reference testing method stored in the memory, determining, with the processor, a bias between the evaluation testing method and the reference testing method, based on the results stored in the memory, comparing, with the processor, the determined bias relative to the determined level of variance in the reference testing method, and based on the comparison, generating a report indicating whether the evaluation testing method is clinically equivalent to the reference testing method, and outputting the report to an output device.
