In February 2017, American triathlete Beth Gerdes was given a 2-year suspension for presence of ostarine, and American triathlete Lauren Barnett was given a 6-month suspension for the presence of Ostarine. Both triathletes claimed contamination from salt tablet supplements. Lauren Barnett was able to provide tablets and sealed bottle tablets which both tested positive for contamination, thus only the 6-month suspension. The 2-year suspension still stands for Beth Gerdes who provided tablets for testing, but tests showed only low levels of ostarine not high enough to confirm the finding. 
This is a powerful drug for the control of atrial and ventricular arrhythmias.

Patient A probably has many more enlarged abdominal nodes that cannot be felt by mere physical exam, but given his bulky lymphadenopathy (big word that means swollen nodes or glands) and swollen spleen (“splenomegaly”), chances are good a CT scan will find a lot more enlarged lymph node clusters in his abdomen. The 30K ALC in his blood test is nothing . It is a mere tip of the iceberg, as much as 90% or more of his disease burden (total number of CLL cells in the body) are in those swollen lymph nodes, spleen, may be liver and bone marrow, beyond the reach of a mere blood test.
