About Kidney function tests

What is the kidney function test?

The kidney function test is a comprehensive test of both kidney and liver function. The kidneys filter the blood, remove waste and regulate fluid balance, whilst the liver metabolises fats, carbohydrates, proteins, ammonia, produces cholesterol and processes bilirubin. The waste products of liver metabolism are transported to the kidneys before being excreted in the urine. Normal kidney and liver function can be measured by looking at biological markers such as creatinine, a waste product that must be filtered and excreted by the kidneys and bilirubin, a substance processed by the liver.

Why take this test?

This test measures the level of proteins and substances in the blood related to kidney and liver function. It can be used to investigate kidney and liver diseases.
