📖About Kidney Function Test
A kidney function test measures substances in the blood, primarily creatinine, blood urea nitrogen and electrolytes, to assess how effectively the kidneys are filtering waste from the body. The results are used to calculate the estimated glomerular filtration rate (eGFR), a key indicator of overall kidney health and the stage of any chronic kidney disease present. It is used to screen at-risk individuals, diagnose acute or chronic kidney impairment, and monitor known kidney disease or the kidney-related effects of medications. Because kidney function often declines silently, regular testing is important for patients with diabetes, hypertension or a family history of kidney disease.
