Serum Creatinine Test

Serum Creatinine Test

The serum creatinine test is used to measure the levels of creatinine in your blood.

What is Creatinine?

Creatinine is a waste product from the breakdown of creatine found in your muscles. This test is performed to see how well your kidneys are working.

Each kidney is made up of tiny blood-filtering structural units called nephrons. The nephrons filter blood constantly through a very small cluster of blood vessels called glomeruli. These filter waste products, excess water, and impurities of blood. These toxins are stored in the bladder and removed through urination. Creatinine is eliminated through a kidney from our body. Hence measuring the level of creatinine in the blood indicate your kidney function. High levels of creatinine in blood show kidney impairment.

Why creatinine test is recommended?

This test may be recommended to you as a part of your regular medical checkup. It is usually given with routine blood tests.

Factors like age, gender, race, health history and glomerular filtration rate (GFR) are also considered in measuring the functioning of the kidney. Usually, blood urea nitrogen (BUN) is also done along with your serum creatinine test.

Creatinine level depends on the muscle mass you have. It varies in men, women, and children depending on their age. Your test results may not always indicate a problem with your kidney. Ask your healthcare provider about your results.
