Which laboratory tests are performed to assess and monitor kidney function?

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

Most people with kidney malfunctions do not have any symptoms until a more advanced phase is reached. Therefore, it is essential to diagnose and treat nephrological conditions from an early stage since a severe disorder can lead to kidney failure if left untreated.

The tests that can assess kidney function are:

  • blood tests: check the glomerular filtration rate (GFR)
  • urinalysis: check for the amounts of albumin in the urine (ACR)

These assessments 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.

Complementary tests to monitor kidney function

Kidney function tests are regular procedures using blood or urine to help identify kidney issues. Further investigations may be advised for assessing the size, shape, and anatomy of kidneys:

  • additional blood tests: serum creatinine, electrolytes, and blood urea nitrogen (BUN)
  • imaging tests: renal ultrasounds, MRIs, or CT scans may be required to determine the causes of kidney disease

The results evaluate your overall kidney health and establish a treatment plan for your particular condition.
