3. Laboratory tests per clinical protocol. The clinical standard of care will be followed in performing post-Tx monitoring labs consisting of complete blood count with differential count, serum sodium, potassium, chloride, bicarbonate, BUN, creatinine and glucose, and liver function tests consisting of Total bilirubin, aspartate alanine transaminase (ALT), aspartate glutamine transaminase (AST), and glutamyl galactosyl transaminase (GGT), and TAC whole blood concentrations. These laboratory tests are performed at least weekly in the first and second months, twice monthly in month 3, and monthly thereafter to the sixth month. The extra 1 to 11 ml needed for pharmacodynamic and pharmacogenomic studies is discussed further in items 5 and in Table 1.
