These findings can be used for genetic counseling and policy decisions regarding carrier screening for TSD in populations of French-Canadian descent. © 2020 National Society of Genetic Counselors.Stanozolol is still the most commonly used illicit anabolic-androgenic steroid (AAS) in professional sports. Therefore, accurate and fast analysis and long detection windows are of high interest in the field of anti-doping analysis. In this work, a very simple, fast and highly sensitive online solid-phase extraction method coupled with liquid chromatography - high-resolution tandem mass spectrometry (HPLC-HRMSMS) for the analysis of stanozolol-N-glucuronides was developed. This fully validated procedure is characterized by only a few manual steps (dilution and addition of internal standard) in the sample preparation. A limit of identification (LOI) of 75 pg/ml, high accuracy (87.1% - 102.1%), precision (3.1% - 7.8%) and sensitivity was achieved. Furthermore, good linearity (> 0.99) and robustness, as well as no carry-over effects, could be observed. In addition to excellent confirmation analysis performance, this method shows sufficient potential for the identification and characterization of unknown metabolites. Using this method, it was possible to unambiguously confirm the presence of 1'N- and 2'N-stanozolol-glucuronide in human urine for the first time due to the access to reference material.

As a retrovirus, its genome is highly variable and easily recombined between different subgroups. Previous studies found several recombinant events among subgroup A, B, and E, but few data s
