Time to integrate cystatin C into clinical practice
Webinar | March 25th, 2026 | 09:00 AM PT / 12:00 PM ET / 06:00 PM CET
For decades, serum creatinine has been the cornerstone of kidney function assessment. Yet clinicians and laboratorians know its limitations. Creatinine levels are influenced by age, sex, diet, and muscle mass, which can lead to misclassification of kidney function in many patients.
Cystatin C has emerged as a powerful alternative biomarker for estimating glomerular filtration rate (GFR). Produced by all nucleated cells at a constant rate and less affected by muscle mass, cystatin C offers a more reliable assessment of kidney function in many clinical scenarios.
About the webinar:
Beyond creatinine: Why it’s time to integrate cystatin c into clinical practice
In this webinar Dr. Potok, Assistant professor of Clinical Medicine, Division of Nephrology-Hypertension, University of California, San Diego, will review the biological basis of cystatin C, identify patient populations most likely to benefit from testing, and provide guidance on interpreting results, especially when creatinine and cystatin C based eGFR differ. Current barriers to cystatin C testing and implementation in routine clinical practice will be discussed. In addition, the role of cystatin C in medication dosing will also be addressed.
Join Dr. Potok as she explores how cystatin C can move from guideline recommendation to everyday clinical practice, with the latest KDIGO guidelines recommend measuring serum cystatin C in patients with Chronic Kidney Disease (CKD) to confirm diagnosis and refine prognostic assessment.
This webinar is designed for clinicians, laboratory professionals, and healthcare providers seeking practical guidance on modernizing kidney function assessment.

Meet Dr. O. Alison Potok
Assistant professor of Clinical Medicine, Division of Nephrology-Hypertension, University of California, San Diego
Dr. O. Alison Potok pursued her medical education in Paris, France at the Université Paris V. She completed a residency in internal medicine at the University of Pennsylvania Health System, in Philadelphia, PA, and pursued a nephrology fellowship at the University of California, San Diego (UCSD).
She was awarded the prestigious American Kidney Fund Clinical Scientist in Nephrology fellowship grant and is currently funded by an NIH career development award. She was appointed assistant professor of clinical medicine at UCSD in August, 2021. Dr. Potok’s research focuses on improving understanding of kidney function measurements, especially the clinical implications of cystatin C vs creatinine-based GFR estimates. She co-authored a review on cystatin C and has been interested in including cystatin C in risk prediction models for chronic kidney disease progression.
