Kidney Profile
Blood Urea Nitrogen (BUN): Urea measured as Blood Urea Nitrogen (BUN) is a waste product obtained from natural breakdown of protein in the liver. It is excreted in the urine after it has filtered through the kidneys. The Urea Nitrogen level reflects both the metabolism of the protein and the effectiveness of the kidneys filtering blood.

  • High BUN levels could mean: Chronic renal disease, acute renal failure, ketoacidosis, dehydration, GI bleeding
  • Low BUN levels could mean: Late normal pregnancy, decreased protein intake, IV fluids, SIADH, severe liver damage
  • BUN/Creatinine Ratio: Urea Nitrogen/Creatinine result. Can determine whether elevated urea nitrogen is due to impaired kidney function or to other factors such as dehydration, urinary blockage, or excessive blood loss.
  • Creatinine: Creatinine is derived from muscles and released into the blood. It is removed from the body by the kidneys. When creatinine level is elevated, a decrease in kidney function is suggested.
  • High Creatinine levels could mean: Renal disease, insufficiency, low glomerular filtration
  • Low Creatinine levels could mean: Decreased muscle mass, severe liver disease
  • Uric Acid: Serum Uric Acid measurements are useful in the diagnosis and treatment of numerous renal and metabolic disorders, including renal failure, gout, leukemia, psoriasis, starvation or other wasting conditions, and in patients receiving cytotoxic drugs.
  • High Uric Acid levels could mean: Gout, kidney stone, inborn error of metabolism, diuretics, disseminated neoplasms, alcohol consumption, renal failure, hypertenstion
