A complete clinical guide to cystatin C testing at home, normal ranges, optimal targets for longevity, and how cystatin C-based eGFR outperforms creatinine in detecting early kidney decline.
Read clinical reviewHow to read your Cystatin C result at every age, what optimal versus normal ranges mean, and why this biomarker beats creatinine-based eGFR for detecting early kidney decline in clinical and longevity practice.
Read clinical reviewA clinician-reviewed deep dive into cystatin C reference ranges, longevity-medicine targets, and how this kidney biomarker outperforms creatinine-based eGFR for predicting cardiovascular, cognitive, and all-cause mortality risk.
Read clinical reviewA clinical deep-dive into how common medications alter cystatin C levels, what the optimal and normal ranges mean, and how to interpret eGFR-cystatin C in patients on TRT, GLP-1s, corticosteroids, and other therapies.
Read clinical reviewA clinician-reviewed guide to interpreting cystatin C rate-of-change, normal ranges, optimal targets, and what serial measurements reveal about kidney aging and GFR decline.
Read clinical reviewCystatin C levels differ by sex, menstrual cycle phase, pregnancy, and hormone therapy. Learn the optimal range, how hormones shift results, and when creatinine-based eGFR misleads.
Read clinical reviewHow diet, fasting, and specific nutrients shift cystatin C levels, what the optimal range looks like, and how to interpret your result in the context of what you ate before the test.
Read clinical reviewHow aerobic training, resistance exercise, and chronic physical activity affect Cystatin C levels, eGFR accuracy, and kidney function interpretation. Clinician-reviewed guide with normal ranges, optimal targets, and evidence-based protocols.
