Kidney biochemical tests are mainly to diagnose the kidneys, observe the development of kidney disease, through the serum urea nitrogen, serum creatinine, blood creatinine excretion rate and other indicators to check whether the normal renal function.
Serum urea nitrogen is measured by examining the nitrogen content in the blood to calculate the urea content, to detect whether the renal function is in normal state. Urea is the major end product of protein metabolism taken from food and excreted into the urine via the kidneys. Once the kidneys are abnormal, unable to excrete urea, leaving it in the blood, the blood urea nitrogen content will increase.
Serum creatinine test is to check the blood creatinine content, creatinine is the product of human muscle metabolism, decreased renal function, the blood creatinine content will increase. Serum creatinine levels provide an important reference for examining renal function. Can not accurately determine the initial renal disease, serum creatinine blood creatinine clearance rate can provide a supplementary basis.
Endogenous creatinine clearance rate is to check how many ml of glomerulus within 1 minute of blood filtration, to determine whether the normal renal function is an important indicator. Inspection method with a short time method and 24 hours two, generally using a short time method. Women are taller than men, but after they age, their kidney function declines and their values decrease.
