• Serum Creatinine & eGFR: Measures creatinine, waste product healthy kidneys filter out, and uses it to calculate the estimated glomerular filtration rate, the standard measure of kidney function. 
  • Blood Urea Nitrogen (BUN): Checks the level of urea in the blood, which tends to rise as kidney function declines. 
  • Electrolyte Panel: Reviews sodium, potassium and other electrolytes, which kidney disease can push out of normal range.
