Total System Error

The generally accepted standard for quality of a result from any test method relates to the difference between the result obtained and the reference value. That difference is referred to as "Total System Error", which is a measure of both accuracy of the system (i.e., the bias of the system, or how close the average of a series of results on the same sample are to the reference value) and precision (i.e., the reproducibility of the system, or how a close a series of results on the same sample are to each other).
