Every year before the Chinese New Year, it is a small peak of physical examination in major companies, and when many people get the physical examination report, they will be very worried when they look at the small arrow marked on it, for fear that they will have some disease.
But many people don't know much about some of the above tips, such as low-density lipoprotein, triglycerides, total cholesterol, uric acid, glycosylated hemoglobin, and so on.
In fact, the above are basically some routine items that will appear in the physical examination report, mainly reflecting the blood sugar, blood lipids, blood pressure, etc., and preventing chronic diseases such as diabetes, gout, and hyperlipidemia as soon as possible.
At the same time, some of these indicators can reflect kidney health, so which indicators are abnormal and can reflect kidney problems?
How to read the three indicators of kidney function in the physical examination report?
Generally speaking, the three indicators of kidney function in the physical examination report, namely serum urea nitrogen, serum creatinine and uric acid, are important indicators to evaluate the health of the kidney.
Knowing the normal range and abnormalities of these indicators can help us better understand whether there is a problem with the kidneys and take appropriate measures in time. Next, we will analyze in detail the kidney problems represented by these three index abnormalities.
1. Serum urea nitrogen (BUN):
Serum urea nitrogen is an indicator of the ability of the kidneys to excrete urea, which is a metabolite of urea produced by liver metabolism that is excreted in the kidneys.
Normally, the reference range for serum urea nitrogen is 7 to 20 mg dl. When serum urea nitrogen is above the normal range, it may indicate the following kidney problems:
1.Renal insufficiency: impaired filtration of the kidneys, resulting in inefficient excretion of urea, resulting in an increase in serum urea nitrogen. Common causes include chronic kidney disease, acute kidney injury, etc.
2.Dehydration: Dehydration leads to hemoconcentration, decreased excretion of urea, which leads to an increase in serum urea nitrogen.
3.High-protein diet: Consuming too much protein increases the amount of urea produced by the liver, resulting in an increase in serum urea nitrogen.
2. Blood creatinine (CR):
Blood creatinine is an indicator of glomerular filtration function, which is a metabolite produced by muscle metabolism and excreted by the kidneys.
Normally, the reference range for serum creatinine is 06-1.2 mg dl (male) and 05-1.1 mg dl (women). When blood creatinine is above the normal range, it may indicate the following kidney problems:
1.Renal insufficiency: impaired glomerular filtration, resulting in an inability to excrete serum creatinine effectively, resulting in an increase in serum creatinine. Compared with serum urea nitrogen, serum creatinine is a more accurate indicator of changes in glomerular filtration.
2.Muscle damage: Muscle damage leads to an increase in the release of blood creatinine, which causes an increase in blood creatinine. Therefore, when interpreting serum creatinine abnormalities, it is important to consider whether there is an element of muscle damage.
3. Uric acid:
Uric acid is a purine metabolite that is excreted mainly through the kidneys. Normally, the reference range for uric acid is 24-7.0 mg dl (male) and 14-5.7 mg dl (women). When uric acid is above the normal range, it may indicate the following kidney problems:
1.Hyperuricemia: The kidneys' ability to excrete uric acid decreases, causing uric acid to accumulate in the body, causing an increase in uric acid. Hyperuricemia is one of the main causes of gout.
2.Decreased glomerular filtration: Decreased glomerular filtration leads to decreased excretion of uric acid, which can lead to an increase in uric acid.
Conclusion:
Through the analysis of the three indicators of kidney function in the physical examination report, we can preliminarily understand whether there is a problem with the kidney.
Elevated serum urea nitrogen and serum creatinine may indicate renal insufficiency, while elevated uric acid may indicate hyperuricemia or decreased glomerular filtration.
However, abnormalities in these indicators do not identify specific ** and require a comprehensive analysis in combination with clinical symptoms and other examination findings.
If you find that your kidney function is abnormal, it is recommended that you consult a doctor in time and receive further examinations and**, once you find that there is a problem with your kidneys, it is recommended that you do it in time** to avoid causing more serious problems.
