Which laboratory tests are performed to assess and monitor the function of kidneys?

In order to asses and monitor the kidney functions imaging tests such as ultrasound, MRI or CT scans may be advised, as well as blood tests and urine tests.

A majority of people with kidney malfunctions do not have any symptoms until a more advanced stage is reached. The tests that can assess kidney health are blood and urine tests. The blood test checks the glomerular filtration rate (GFR) and the urine test checks for the amounts of albumin in the urine.

These tests can also be done to evaluate the progression of kidney disease. Monitoring of kidney functions may be done by keeping track of the GFR and urine test results regularly. Control of blood pressure levels at the advised limit maintains kidney functions.

Other blood tests such as serum creatinine, electrolytes, and blood urea nitrogen (BUN) may be performed.

Imaging tests such as a renal ultrasound may be advised for assessment of the size, shape, and anatomy of kidneys. MRI or CT scan may be required to evaluate the causes of kidney disease.
