Multi-mycotoxin analysis using dried blood spots and dried serum spots [PDF]

Analytical and Bioanalytical Chemistry, 2017
In this study, a rapid multi-mycotoxin approach was developed for biomonitoring and quantification of 27 important mycotoxins and mycotoxin metabolites in human blood samples. HPLC-MS/MS detection was used for the analysis of dried serum spots (DSS) and dried blood spots (DBS).
