The kidneys are vital organs responsible for filtering waste products from the blood, regulating fluid balance, blood pressure, and electrolytes. This test measures seven important markers that together provide a complete picture of kidney function and electrolyte balance. It is important for fatigue, high blood pressure, swollen ankles, low urine output, or when taking medications that can strain the kidneys.\u003c\/p\u003e\n\n\u003ch2\u003eWhat is tested?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCreatinine\u003c\/strong\u003e – Waste product from muscle tissue for kidney function assessment\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eeGFR\u003c\/strong\u003e – Estimated glomerular filtration rate (kidney function percentage)\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUrea (BUN)\u003c\/strong\u003e – Waste product produced by the liver and excreted by the kidneys\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSodium\u003c\/strong\u003e – Electrolyte for fluid balance and nerve function\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePotassium\u003c\/strong\u003e – Electrolyte for heart function and muscle function\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChloride\u003c\/strong\u003e – Electrolyte for acidity and fluid balance\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlbumin\u003c\/strong\u003e – Protein for osmotic pressure; abnormalities indicate kidney or liver problems\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy should you have a Kidney Function Blood Test?\u003c\/h2\u003e\n\u003cp\u003eThis test is crucial for early detection of kidney problems. Kidney disease often progresses silently without symptoms until severe damage occurs. The test is recommended for risk factors such as diabetes, high blood pressure, heart problems, a family history of kidney disease, or when using kidney-straining medications (painkillers, blood pressure medication, antibiotics). Kidney function should also be checked with symptoms such as fatigue, swollen ankles, low or high urine output, foamy urine, or high blood pressure. Early detection allows for treatment to prevent further deterioration.\u003c\/p\u003e\n\n\u003ch2\u003eWhat does it indicate?\u003c\/h2\u003e\n\u003cp\u003eThe results show how efficiently your kidneys filter waste products and whether electrolytes are in balance:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter function\u003c\/strong\u003e – Creatinine and urea rise when kidneys filter less effectively\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKidney function percentage\u003c\/strong\u003e – eGFR indicates the percentage of normal kidney function (normal is above 90%)\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrolyte balance\u003c\/strong\u003e – Sodium, potassium, and chloride for heart function, nerve function, and fluid balance\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtein loss\u003c\/strong\u003e – Albumin provides insight into protein loss through the kidneys\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDisruptions can indicate kidney disease, dehydration, heart failure, or side effects of medication.
