A system and method of providing a confidence test in one embodiment includes determining a first quality metric based upon a first and a second test environment wherein the second test environment is different from the first test environment, exposing a sample to a plurality of test sites, establishing the first test environment at a first of the plurality of test sites, establishing the second test environment at a second test site, obtaining a first detection signal associated with the first of the plurality of test sites exposed to the sample and at the first test environment, obtaining a second detection signal associated with the second of the plurality of test sites exposed to the sample and at the second test environment, determining a second quality metric based upon the first detection signal and the second detection signal, and comparing the second quality metric with the first quality metric.
