    Dried Blood Spots for Doping Purpose-Two-Step Protocol for Analysis of Non-Threshold Substances and Anabolic Steroid Esters From One Spot/Pebble

    A validated two-step LC-MS/MS protocol can identify 91 prohibited doping agents from a single dried blood spot collected on either cellulose cards or volumetric absorptive microsampling devices.

    Improvement of EPO Transgene Detection From Polymeric Dried Blood Spots for Antidoping Application

    In a head-to-head comparison of three DBS devices, polymeric Tasso-M20 and Neoteryx Mitra outperformed cellulosic Whatman 903 for EPO transgene detection;

    Quantitation of BCAA and BCKA in plasma and patient-centric dried blood microsamples in a clinical setting

    A comparison of three patient-centric dried blood microsampling devices, paper DBS, Mitra and Tasso-M20, found strong to excellent correlation with traditional venous plasma for measuring branched-chain amino acids and ketoacids.

    Detection of a Single Microdose of Testosterone and Recombinant EPO in Healthy Volunteers

    The authors found that a single microdose of recombinant EPO was detectable up to 72 hours using ITP and CP methods, though the Tasso microsampling device showed lower sensitivity than Mitra and Capitainer.

    Comparability of different analytical workflows for steroid esters detection in doping control field

    The study compared five microsampling devices, including Mitra tips and Tasso-M20, for detecting 27 steroid esters in dried blood by LC-MS/MS, and found that methanol extraction with Girard's reagent P or T provided the best screening sensitivity with detection limits of 0.05 to 1.0 ng/mL, while methoxyamine derivatization was recommended for confirming boldenone and certain testosterone esters.
