WebIn spike-and-recovery, a known amount of analyte is added (spiked) into the natural test sample matrix and its response is measured (recovered) in the assay by comparison to an identical spike in the standard diluent. WebA spike-and-recovery experiment is designed to assess this difference in assay response. Performing a spike-and-recovery experiment A known amount of analyte is added to the sample matrix and standard diluent. The two sets of responses are compared based on values calculated from a standard curve.

WebSpike recoveries on samples are used to detect systematic errors due to the sample matrix, or to evaluate the stability of a sample after its collection. Ideally, samples are spiked in the field at a concentration that is 1 to 10 times the analyte’s expected concentration or 5 to 50 times the method’s detection limit, whichever is larger. WebJul 17, 2024 · Whenever we develop a new method, recovery is done is several matrices and even different types of samples. As a result one gets a range of recovery values in different matrices or for different samples. It is better to say that a method shows gives a recovery between 95% to 115%.
