Abstract
The present disclosure provides a set of spiked matrix standards comprising: one or more carriers, each carrier comprising: (a) a reference standard analyte in an amount that is different in each carrier; and (b) a blank matrix that is in admixture or in contact with the reference standard analyte. Methods for preparing and quantitating an analyte in a test sample comprises (a) providing one or more test samples to be tested for the presence of the analyte (b) providing a set of spiked matrix standards; (c) processing the standards and test samples and (d) quantitating the amount of analyte in each of the standards and test samples.
