WebAnalytical sensitivity: The assay’s ability to detect very low concentrations of a given substance in a biological specimen. Analytical sensitivity is often referred to as the limit of detection (LoD). LoD is the actual concentration of an analyte in a specimen that can be consistently detected ≥ 95% of the time. WebLinearity is the method’s ability to obtain test results, which are directly proportional to the concentration of the analyte in the sample. (1) The term “linear” can in mathematics refer to the fact that the statistical models considered are linear in terms of all parameters (coefficients), also including polynomial relationships.
