  • a On a per-test basis.

  • b S/N, signal to noise. Mean, ratio of the average signal generated from all samples positive for a specific target to the average noise generated from all samples negative for the same target; minimum, ratio of the lowest signal generated from a sample positive for a specific target to the highest noise generated from a sample negative for the same target.
