|Blood Urea Nitrogen (BUN)||The BUN measures the amount of urea in the blood, which is a byproduct of protein breakdown. It is filtered by the kidneys and excreted in the urine. Its level in the blood increases in kidney disease, though other conditions may also be responsible.|
|Blood Urea Nitrogen (BUN) – Serum creatinine ratio||The ratio of blood urea nitrogen (BUN) and serum creatinine is a calculated value that helps to determine the possible cause of kidney dysfunction.|
|Serum creatinine||Creatinine is a breakdown product of muscles and is removed from the body by the kidneys. Its level in the blood increases in rhabdomyolysis, a condition where the muscles break down, or kidney disease, beside some other conditions.|
|Serum sodium levels||The serum sodium levels are maintained in a range of between 135 to 145 mmol/L. Low or high sodium levels may be associated with changes in fluid volume within the blood vessels.|
|Serum uric acid||Uric acid is a waste product that is eliminated by the kidneys through the urine. High levels result in gout, a condition that results in joint swellings, and kidney stones.|
