Kidney Function Markers

Meaning

Kidney Function Markers are specific biochemical substances measured in blood or urine that provide quantitative data on the renal system’s capacity to filter waste, maintain fluid balance, and regulate electrolyte concentrations. These markers serve as clinical indicators for assessing overall renal health, detecting early signs of injury, and monitoring the progression of kidney disease. Key markers often include creatinine, urea nitrogen, and estimated Glomerular Filtration Rate (eGFR), offering essential insight into the body’s excretory efficiency. Regular evaluation of these markers is a cornerstone of preventative and diagnostic medicine.
