Nettet* LoD = LoB + 1.645(SD (low concentration sample)). * LoQ is the lowest concentration at which the analyte can not only be reliably detected but at which some predefined goals for bias and imprecision are met. The LoQ may be equivalent to the LoD or it could be at a much higher concentration.

NettetDetection capability (CCβ) – the concentration level of the analyte in the sample at which there is a probability β (again usually defined as 0.05 or 5%) that the method will give a result lower than CCα, meaning that the analyte will be declared as undetected.
