Detection of Anabolic Androgenic Steroids and Steroid Esters-Comparing Dried Blood Spots Collection Devices and Urine Samples. [PDF]

Drug Test Anal
DBS (Capitainer‐B50 and Tasso‐M20) enabled detection of testosterone esters in all participants, whereas urine testing (T/E) missed cases including potential UGT2B17 del/del carriers and individuals with testosterone prescription. More AAS and steroid‐esters could be detected in Capitainer‐B50 versus Tasso‐M20.
