Spike and recovery method
WebSpike recovery analysis demonstrates that the assay can recover added HCP or other impurity or contaminant spiked into that sample matrix; usually performed for final product or in-process samples. For more information, watch the video, "Dilution Linearity and Spike Recovery". Learn More Orthogonal Coverage Analysis by AAE™ 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.

WebIf 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. Correcting for poor spike-and-recovery results. Two kinds of adjustments can be made to re-optimize an ELISA when a spike-and-recovery experiment detects a discrepancy. WebTo test a glucometer, a spike recovery is carried out by measuring the amount of glucose in a sample of a patient’s blood before and after spiking it with a standard solution of …
WebSpike-and-recovery and linearity-of-dilution experiments are important methods for validating and assessing the accuracy of ELISA. Spike and recovery is used to determine … Webstandard curve range. Use this dilution for the spike/recovery and linearity assays. If sample value is unknown, preliminary testing of a serial-dilution of the sample, such as neat, 1:10, and 1:20, should be run to establish sample value, prior to performing spike/recovery and linearity tests.)
