             equation (listed below) using serum creatinine measured at screening, confirmed via a
             single repeat, if deemed necessary

          6. Subject with a positive result for hepatitis B surface antigen (HBsAg), hepatitis B
             core antibodies (HBc Ab) or hepatitis C virus (HCV) antibodies
