Bilirubin, normal CRP,normal WBCs...his biopsy was negative for rejection or viral reactivation twice, his HBc Ab IgM was negative, his CMV level was not detected, no biliary dilatation in US, he had collection in US and was drained US guided.
He is on FK since post op. and his trough level always bellow 15 ng, enzymes decrease spontaneously and re rised again.
