Witrynaexample, if an undiluted serum sample produces poor spike and recovery, perhaps one that is diluted 1:1 in standard diluent will work better. If the level of analyte in the diluted sample is sufficient to be detected by the assay, this method will correct many recovery problems. Better results for a sample matrix may be obtained by altering its ...
