## What is Norwich GFR Assessment System?

Norwich GFR is a teaching clinical utility app designed for nuclear medicine professionals to learn how to accurately assess glomerular filtration rate (GFR) using the plasma clearance technique. GFR is a critical marker of renal function, particularly valuable in situations where precise kidney evaluation is required.

The app supports the common use of Tc-99m DTPA as a radiopharmaceutical agent, enabling users to estimate renal filtration performance from timed blood sample measurements following tracer injection.

Use cases in teaching and training include:

Pediatric renal evaluation

Preoperative assessment prior to nephrectomy

Renal transplant follow-up

Oncology: patient eligibility for nephrotoxic chemotherapies (e.g., cisplatin, carboplatin)

Whether in a hospital setting or research environment, Norwich GFR simplifies data entry, streamlines workflow, and helps ensure accurate interpretation of GFR results.
