Limit of Detection. The lowest concentration of a substance that can be determined to be significantly different from zero.

limit of detection. Lowest concentration of a pesticide residue in a defined matrix where positive identification can be achieved using a specified method.

Limit of Detection. The minimum concentration of an analyte that, in a given matrix and with a specific method, has a 99% probability of being identified, qualitatively or quantitatively measured, and reported to be greater than zero.

Limit of detection. (AIHA, 1996)

Limit of detection. The lowest concentration of an analyte that the bioanalytical procedure can reliably differentiate from background noise.

Limit of detection, the lowest level at which a chemical can be measured in a sample by the analytical method used.
