Kidney Function Test

A kidney function test, also called a renal function test, is a group of tests that help measure how well your kidneys are working. Your kidneys filter wastes and excess fluid from your blood. They also make hormones that help control blood pressure, red blood cell production, and the balance of minerals in your body. To find out how well your kidneys are working, your doctor may order one or more of the following tests:

-A creatinine test measures the level of creatinine in your blood. Creatinine is produced when muscle tissue breaks down. High levels of creatinine may mean that your kidneys are not filtering waste products from your blood as they should.

A kidney function test, also called a renal panel or a serum creatinine test, measures the level of creatinine in your blood. Creatinine is produced by the muscles and released into the bloodstream. A high level of creatinine may indicate that your kidneys are not working properly. A kidney function test, also called a renal function test, measures the amount of waste products in your blood and urine.

Waste products in the blood can come from many sources, including the breakdown of red blood cells, the metabolism of protein, and the digestion of food. When your kidneys aren't working properly, these waste products can build up and cause health problems. A kidney function test usually includes a measurement of creatinine in the blood and urine. Creatinine is a waste product that is created when muscle tissue breaks down. It's a good indicator of how well your kidneys are removing wastes from your body. The higher the creatinine level, the less well your kidneys are working.
