WebSep 8, 2024 · What is Spike recovery method? In spike and recovery, a known amount of analyte is added (spiked) into the natural test sample matrix. Then the assay (here assumed to be ELISA) is run to measure the response (recovery) of the spiked sample matrix compared to an identical spike in the standard diluent. WebThe Spike and Recovery method is an important technique for analyzing and accessing the accuracy of ELISA and other analytical methods for particular sample types. It is used to determine whether analyte detection can be affected by the difference between diluent used for preparation and the experimental sample matrix. margin cushion meaningWebIf the recovery differs, then components in the sample matrix are causing the difference, and adjustments must be made to the method to minimize the discrepancy.
