Rethinking CKD Evaluation: Should We Be Quantifying Basal or Stimulated GFR to Maximize Precision and Sensitivity?

Area of Science:

• Nephrology
• Biomedical Engineering
• Medical Diagnostics

Background:

• Chronic kidney disease (CKD) presents a growing clinical challenge with limited diagnostic tools for severity and progression.
• Current methods lack commercial surveillance technology to precisely quantify glomerular filtration rate (GFR) loss.
• This diagnostic gap hinders early intervention and therapeutic development for CKD.

Purpose of the Study:

• To highlight the advantages of quantifying stimulated GFR by assessing renal reserve in CKD patients.
• To review advanced fluorescent technologies for measuring basal and stimulated kidney function.
• To enable earlier diagnosis and personalized treatment strategies for CKD.

Main Methods:

• Review of existing literature on CKD progression and diagnostic limitations.
• Exploration of optical measurement techniques for kidney function assessment.
• Discussion of renal reserve activation for enhanced GFR quantification.

Main Results:

• Stimulated GFR measurement, by activating renal reserve, offers a potential advantage for improved GFR quantification.
• Optical technologies show promise for minimally invasive or noninvasive assessment of kidney function.
• Early and precise GFR measurement can facilitate individualized therapy.

Conclusions:

• Quantifying stimulated GFR by assessing renal reserve is crucial for early CKD diagnosis and management.
• Advancements in optical measurement technologies are paving the way for personalized patient care.
• Early intervention based on precise GFR assessment can significantly improve patient outcomes in CKD.
