It provides to assess the range of concentrations for which the method can reliably function. Analytical method validation is an essential requirement to perform the chemical evaluation [ 1, 2, 3 ]. Graphically it represents a straight line when plotted against each other. 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. LINEARITY Definition:- Linearity is a mathematical relationship between two variable quantities (they may be of the same unit), which are directly proportional to each other. ... Linearity: Linearity of a technique is its capacity to acquire test comes about that is accurate relative to the example fixation over a given range. Linearity is the ability of the method to elicit test results that are directly, or by a well-defined mathematical transformation, proportional to analyte concentration within a given range. Results from method validation can be used to judge the quality, reliability and consistency of analytical results; it is an integral part of any good analytical practice. LOD 7. EP9-A2. The type of validation programme required depends entirely on the particular method and its proposed applications.

M ethods used in pre-clinical studies not required to be performed to GLP should be fit for purpose but not necessari ly developed in a GLP facility. Linearity commonly understood as proportional relationship between two units, in context of method validation, it refers toproportional relationship between test results and concentrations. Basic validation philosophy. Precision 2. Keton Consulting offers the most complete line of Calibration Verification and Linearity products designed to assist with CLIA-88 revalidation. The reason being that, if the analyte signal in samples is linear, then it is almost certain that it is also linear in calibration solutions, while the opposite might not be true. Analytical Method validation. Acceptance criteria should be r 2 >-0.99. 2. Although the Analytical Methods Committee and some articles on analytical validation discouraged using the correlation coefficient in the context of testing for linearity , , , , many laboratories around the world base the linearity of their instrumental methods on a so-called (by the author of the present article) “r-test”.
