In Accordance with Northwestern University’s Office for Protection of Research Subjects, Northwestern University will follow the guidelines for contrast administration set forth by Northwestern memorial Hospital (NMH). Current NHM policy states, “Prior to a radiology exam requiring gadolinium based contrast media all patients will have renal function assessed via estimated glomerular filtration rate (eGFR) on the day of the exam (within 24 hours).”
The Center for Translational Imaging (CTI) uses IStat to obtain eGFR results within 24 hours. If you have other means you will need to demonstrate this information before contrast is given.
I-STAT
- Point of Care I-STAT testing is a service that is provided by NMH and will be billed to the PI by NMH.
- RN starts IV and draws blood sample from IV for I-STAT testing. Allow 30 minutes for IV start, processing, and results.
- Any subjects taking Hydroxyurea also known as Hydrea, Droxia, and Mylocel will need to come in 1 ½ hours prior so the blood can be taken to the lab for process.
Responsible Party: Alexander Korutz, MD Assistant Professor of Radiology
