Limit of Blank, Limit of Detection and Limit of Quantitation
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556583/
WEBSummary. Limit of Blank (LoB), Limit of Detection (LoD), and Limit of Quantitation (LoQ) are terms used to describe the smallest concentration of a measurand that can be reliably measured by an analytical procedure. LoB is the highest apparent analyte concentration expected to be found when replicates of a blank sample containing no analyte are ...

WEBApr 29, 2017 · 1. Introduction. Arguably among the most critical performance parameters for a diagnostic procedure are those related to the minimum amount of target that can be detected and quantified [11]. The parameters describing those properties are known as the limit of detection “LoD” and the limit of quantification “LoQ”.

https://www.chromatographyonline.com/view/limit-detection
WEBProcedure for estimating the critical level and the detection limit. 1. Take a test sample (ideally real but could also be artificially composed), where the concentration of the component is low (close to the expected detection limit). 2. Analyse a minimum of 10 portions following the complete analytical procedure.

Difference from Background: Limit of Detection | Analytical …
https://www.jove.com/science-education/14521/difference-from-background-limit-of-detection
WEBThe limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise.
