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.

The clearing creatinine test measures the amount of creatinine that has been excreted from the blood into the urine over a 24 -hour period.

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).

What is the function of creatinine screening?

Creatinine testing serves to test the ability of the kidneys to filter blood and urine. When kidney function is disturbed, the rate of kidney cleansing will also be disturbed.

The creatinine test is usually also performed in conjunction with other kidney function tests, including the blood urea level (BUN) test. Therefore, a creatinine test is often recommended when a person performs a routine examination.
