Clinical Significance

This panel is usually ordered to monitor patients with chronic kidney disease (CKD) or as part of a health examination for individuals at high risk of developing kidney diseases [1,2].

Kidney disease is more likely to develop in individuals with certain conditions, such as high blood pressure, diabetes, heart disease, and a family history of kidney disease. Early symptoms of kidney diseases are often non-specific. This panel is commonly ordered during wellness checks and emergency-room admissions when symptoms and signs are suggestive of kidney diseases [2]. National Kidney Foundation recommends a kidney profile containing estimated glomerular filtration rate and albumin-creatinine ratio for detecting and monitoring CKD [1].

The results of this test should be interpreted in the context of pertinent clinical and family history and physical examination findings.
