Limit of Detection definition

Limit of Detection or “LOD” means the minimum concentration of a substance that can be measured and reported with ninety-nine percent (99%) confidence that the analyte concentration is greater than zero (0) for a particular analytical method and sample matrix.

Limit of Detection or “LOD” means the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) within a stated confidence limit (generally 1%).

Limit of Detection means the lowest concentration level that can be determined to be statistically different from a blank.

Examples of Limit of Detection in a sentence

U Result is less than the Limit of Detection (LOD) and/or Reporting Limit (RL).
The Lower Limit of Detection (lloq) used was 1.5 ng/mL for the sad part and subsequently upgraded to 0.75 ng/mL for the mad part after introduction of new iCp-ms instrument with greater sensitivity.
However, some samples did yield constituents that were in concentrations between the Limit of Detection (LOD) and Limit of Quantification (LOQ), with one constituent in concentrations higher than the LOQ.
Therefore, this concentration was determined as Limit of Detection for the GSD NovaPrime® SARS-CoV-2 (COVID-19) RT-PCR kit.

More Definitions of Limit of Detection

Limit of Detection or “LOD” means the lowest con- centration or amount of analyte that can be identified, measured, and reported with confidence that the concentration is not a false positive value. For department purposes, the LOD approximates the MDL and is determined per the method cited in sub. (46).

Limit of Detection or “LOD” means the lowest con- centration level that can be determined to be significantly differ- ent from a blank for that analytical test method and sample matrix.

Limit of Detection means the lowest concentration level that can be determined to be statistically different from a blank sample for that analytical test method and sample matrix.

Limit of Detection or “LOD” means a measurement of the concentration of a substance that can be measured and reported with ninety-nine percent (99%) confidence that the analyte concentration is greater than zero (0) for a particular analytical method and sample matrix. The LOD is equivalent to the method detection level or MDL.

Limit of Detection or "LOD" means an estimate of the minimum amount of a substance that an analytical process can reliably detect. An LOD is analyte and matrix specific and may be laboratory dependent.

Limit of Detection means the output signal or concentration value above which it can be affirmed, with a stated level of confidence that a sample is different from a blank sample containing no determinand of interest;

Limit of Detection or “LOD” means the lowest concen- tration or amount of analyte that can be identified, measured, and reported with confidence that the concentration is not a false posi- tive value. The department considers the LOD to be equivalent to the method detection limit and is determined under the method cited in sub. (46).
