Introduction
The five common kidney function tests typically include uric acid, serum creatinine, blood urea nitrogen, cystatin C, and microglobulin. Different medical institutions may vary in their specific test panels. These indicators can effectively reflect the status of kidney function. Additionally, when undergoing kidney function tests, it is important to avoid strenuous exercise to prevent abnormal test results.
Renal function tests typically include five items: uric acid, serum creatinine, blood urea nitrogen (BUN), cystatin C, and microglobulin. Different medical institutions may vary slightly in their testing panels, but these indicators effectively reflect the status of kidney function.
1. Uric Acid
Uric acid is a metabolic byproduct of purines. When kidney function is impaired, uric acid levels are often elevated.
2. Serum Creatinine
Serum creatinine is a metabolic waste product from muscle metabolism and is commonly used to assess whether kidney function is normal.
3. Blood Urea Nitrogen (BUN)
BUN represents protein metabolism byproducts in the body and is frequently used to evaluate kidney function.
4. Cystatin C
Abnormal cystatin C levels are usually caused by decreased kidney function and can effectively indicate whether kidney damage is present.
5. Microglobulin
Microglobulin is a clinical marker used to assess renal tubular function. Elevated microglobulin levels typically indicate impaired reabsorption function in the renal tubules.
In addition, when undergoing kidney function tests, individuals should avoid strenuous exercise, as it may lead to abnormal test results.
