Creatinine is a metabolic product produced by creatine and phosphocreatin in muscle and its daily production is constant. Little creatinine is produced from meat -based foods obtained from the daily diet. Creatinine is carried through the blood to the kidneys. The kidneys filter out creatinine and excrete it in the urine.
Before it is excreted from the body through urine, creatine must first be filtered by the kidneys. Serum creatinine concentration levels should not change if kidney function is working properly.
If the kidneys have problems, creatinine levels can rise and accumulate in the blood. As a result, various diseases of the kidneys and other urinary system (urology) can also appear.
Therefore, screening is needed to test creatinine levels, both in the blood and urine. That way, you can find out how well your kidneys function in filtering or commonly called glomerular filtration rate (GFR).
Creatinine level testing may be necessary if you or someone close to you has symptoms caused by kidney disease, such as:
You may also need this examination if the blood or urine test results show that there is a problem with the kidneys.
In addition, there are several other conditions that can also affect kidney function that may require a creatinine test, which are:
