1. Function of the kidney
The kidney is usually considered to be the "organ that produces urine".

Kidneys are the organs on the left and right sides of the spine on the back of the human body. It is like a broad bean, and although relatively small (about 11 cm x 5 cm), it is a very important organ.
filters the body's garbage to make urine
As we all know, the most important function of the kidney is to remove the body's garbage to make urine. Creatinine is one of the body garbage.
The kidney has the function of filtering harmful substances in the glomerular part, absorbing 99% of the filtrate in the renal tubular part, and expelling the rest into the body as urine.
Other renal functions
According to the guidelines for kidney disease patients, "protect the kidneys" translated by the Japanese Society of Nephrology. In addition to filtering and producing urine, the kidneys also have the following functions.
· By expelling urine, the moisture in the human body is kept balanced.
· Maintain the balance between minerals and sodium, potassium and other compounds.
· Regulates the salt in the body and maintains blood pressure stability.
· It also plays a role in red blood cell production and bone maintenance.
2. The value of creatinine

creatinine value is one of the clues to discover whether renal function is abnormal.
What is creatinine?
The substance called Chrysanitine phosphate is an important source of energy for muscle movement. Creatinine is the human body waste generated after metabolism. Since creatinine is filtered by the kidney and excreted as urine, an increase in serum creatinine concentration means a decrease in renal function.
In addition, creatinine is usually abbreviated as Cr.
creatinine value
creatinine value is expressed in units of mg/dl (mg per deciliter). Standard value:
(male) Standard range: 1.00 or below Warning: 1.01-1.29 Abnormality: 1.30 or above
(female) Standard range: 0.70 or below Warning: 0.71-0.99 Abnormality: 1.00 or above
If the creatinine level is very high, there may be problems with the kidneys. Suspected acute kidney disease, chronic kidney disease, heart failure , etc. (When heart failure occurs, blood is difficult to flow to the kidneys, and the garbage in the body cannot be excreted.)
In recent years, the number of chronic kidney disease has increased. According to the "2012 CKD Clinical Practice Guide " compiled by the Japanese Society of Nephrology, there are 13.3 million chronic diseases of renal insufficiency in Japan, and they will experience symptoms such as nocturia, discomfort, swelling and shortness of breath. When subjective symptoms appear, it can be said that the disease has progressed very seriously. Regular health checks are essential for prevention.
creatinine is a common method for checking kidney function, but its value depends on the number of muscles. Therefore, it varies greatly between men and women. Unless the kidney function drops to about half, it will not show a very high value.
