WebWe also do not have any tests of T cell reactivity (ELISPOT, ImmuKnow®) serially performed on our cases to further study the immune response in this approach in pancreas recipients. We did not have any formal measurements of GFR through measured urine creatinine clearance or iothalamate studies, thus limiting its efficacy on true graft function. WebNephrology Qs Bank 20) The Answer is C: In most cases, either the Cockcroft-Gault or the MDRD equation is appropriate (and best) to assess kidney function. However, this patient is significantly below his ideal body weight and has malnutrition, so equations will likely overestimate his renal function (Answers A and B are incorrect).
