NettetLinearity is achievable for sample recoveries within a range of 80% to 120% of the expected values. Values that fall below two times the limit of quantification for the assay should be avoided in consideration of dilutional data due to statistical limits at the low end of the assay range.

NettetLinearity of dilution refers to the extent in which a spike or natural sample’s (in a particular diluent) dose response is linear and in the desired assay range. Spike and recovery and linearity of dilution are related. Experiments can be designed to test both simultaneously. The following discussion considers each one separately. NettetValidation results may provide verification of sample compatibility and possible sources of interference with future implications on assay optimization. Dilutional Linearity Dilutional linearity determines whether sample matrices spiked with detection analyte above the upper limit of detection can still provide reliable quantification after dilution within …
