Renal Nutrition Roundtable:
Clarity on GFR and Kidney Function Labs
An evidence-based discussion to simplify GFR, kidney labs, and the patient conversations that follow.
Cost: $35
Why this course
A low or declining GFR is often frightening for patients—and unfortunately, many healthcare providers don’t fully explain what GFR means, how CKD is diagnosed, or the limitations of relying on GFR alone. This lack of clarity fuels fear, confusion, and frustration, making it harder for patients to engage in positive diet and lifestyle changes.
This CPE equips dietitians with clear explanations, practical resources, and discussion tools—covering how to interpret kidney labs, what questions patients can ask their doctor, and how to prepare for accurate lab draws. We’ll also explore why trends matter more than single numbers and highlight other factors beyond GFR that are important for assessing kidney health.
With this knowledge, you’ll be able to help patients put their labs into perspective—reducing fear and empowering them to move forward with confidence in their care.

Lindsey Zirker MS, RDN, LD
Lindsey has spent over 20 years specializing in renal nutrition — and she’s just as passionate about it today as when she started. As lead clinical dietitian at the Kidney Nutrition Institute (and previously more than a decade at the Idaho Kidney Center), she’s worked alongside clinicians in every corner of renal care.
She writes a monthly column for Renal, Urology and Transplant journal and has been published in multiple scientific papers, but what truly sets her apart is her ability to take complex nutritional science and make it practical. Lindsey blends cutting-edge research with real-world application so dietitians not only understand the “why” behind best practices, but also the “how” to make them work for patients in everyday clinical settings.
