Which factors require assessment of patient renal function prior to administration of intravascular contrast material?

  • • Patient age >60
  • • History of renal disease, including:
    • • Dialysis
    • • Renal transplant
    • • Single kidney
    • • Renal cancer
    • • Renal surgery
  • • History of hypertension requiring medical therapy
  • • History of diabetes mellitus
  • • Metformin or metformin-containing drug combinations (for iodinated contrast material administration only)

At our institution, when the serum creatinine level is ≤ 1.4 mg/dL, iodinated contrast material can be administered, assuming that there are no other contraindications. When the serum creatinine level is between 1.5 and 1.9 mg/dL or rising, iodinated contrast material can still be administered, but only after a conversation with the referring physician has taken place to discuss the risks and benefits of administering contrast material and possible diagnostic test alternatives. When the serum creatinine level is ≥ 2.0 mg/dL, iodinated contrast material is generally not administered unless there is an urgent medical necessity.
