Linearity criteria
Nettet24. aug. 2024 · Acceptance criteria. Linearity – squared correlation coefficient (r 2 ) = NLT 0.99 for binary. %RSD of peak height obtained for five replicate injections of the sample should be NMT 2.0% for quaternary. Annexure 6: Calibration of UV-Visible / PDA detector by reference energy of the HPLC lamp. NettetRequirements for Linearity. A system is called linear if it has two mathematical properties: homogeneity (hōma-gen-ā-ity) and additivity. If you can show that a system has both properties, then you have proven that the system is linear. Likewise, if you can show that a system doesn't have one or both properties, you have proven that it isn't ...

NettetRecommended Linearity Acceptance Criteria: The assay need not give results that are directly proportional to the concentration (a mount) of analyte in the sample for the test … Nettet13. mai 2024 · The new CLSI EP6-Ed2 protocol no longer requires fitting polynomial models to determine linearity. Instead, the deviation from linearity is calculated as the difference between the mean of each level and a linear fit through the data. That can then be compared against the allowable nonlinearity criteria.

NettetLinearity refers to the relationship between the final analytical result for a measurement and the concentration of the analyte being measured. This distinction is relevant because a plot of analyte concentration versus measurement signal from the instrument may not be linear. The concept of “linearity” is not separately designated by CLIA.
