Diagnosing chronic kidney disease

Area of Science:

• Nephrology
• Internal Medicine
• Diagnostic Medicine

Background:

• Chronic kidney disease (CKD) affects millions globally.
• Accurate diagnosis is crucial for effective management and prognosis.
• Current diagnostic criteria rely heavily on estimated glomerular filtration rate (eGFR).

Purpose of the Study:

• To review the current diagnostic approaches for CKD.
• To evaluate classification systems based on eGFR and kidney damage.
• To assess the role of albuminuria in CKD diagnosis and prognosis.

Main Methods:

• Literature review of current diagnostic standards for CKD.
• Analysis of classification systems incorporating eGFR and markers of kidney damage.
• Evaluation of prognostic data linked to eGFR and albuminuria levels.

Main Results:

• CKD classification systems have limitations, particularly in specific populations like the elderly.
• eGFR alone can be insufficient for diagnosing CKD without other signs of kidney damage.
• Albuminuria, when combined with eGFR, offers significant value in determining CKD prognosis.

Conclusions:

• CKD diagnosis using eGFR alone warrants caution, especially in older adults without evident kidney damage.
• The presence and level of albuminuria are critical for accurate CKD diagnosis and prognosis.
• Integrating albuminuria assessment enhances the diagnostic and prognostic utility of eGFR in CKD.
