Accurate Diagnosis of a Changing Target has Significant Patient Impact

Hemodialysis Patient • Patient with kidney transplant for 10 years• Due to transplant failure on dialysis on 2003• Initial test negative, Abbott HBsAg positive• Confirmed by further serology and DNA test• HBV with changes in 6 amino acid positions: T115R,

P120Q, S154L, E164V, Q181R, S210R

• Avoided potential HBV transmission
