Kidney Function Checks

Blood testing for kidney function levels

Illnesses affecting the kidneys include nephritic syndromes, renal cysts, renal cancer, chronic kidney disease, urinary tract infections, nephritis, urinary tract obstruction and kidney stones.

Kidney Vital Functions

The kidneys serve several vital functions in the human body including maintaining the right amount of fluid and electrolytes in the body, removing excess water, regulating blood pressure, and cleansing toxins from the blood.

They serve as a natural filter of the blood and remove waste from the body. They also reabsorb water, glucose and amino acids, and produce regulatory hormones which control blood pressure, stimulate production of RBCs, and keep your bones healthy.

Test for Optimal Health

Our kidney function blood test looks into whether your kidneys are functioning optimally. They look at the levels of creatinine, urea and potassium in your system.

The most common things that can go wrong with the kidneys include disease and infection, stones, and cancer.


Preparing for test

Please arrive for your blood test well-hydrated.

During the test

The kidney function test requires a simple blood test. A needle is inserted into a vein, usually on the inner arm near the elbow, and a small amount of blood is drawn. You may feel a pricking or scratching sensation.

Type of sample taken:



If you had a consultation with one of our GPs they will give you a call to explain the results to you and suggest the next steps. After the discussion with your doctor you will receive the results by email. If you didn’t have a consultation we will email you the results as they arrive from the laboratory. You can take them to your own doctor for interpretation or you can book an appointment with us. In that case a consultation fee is applicable.


What happens when you have kidney disease?

The kidneys filter toxins and waste from your blood, and help to control blood pressure. When the kidneys are diseased, they stop being able to perform this function.

What are the symptoms of kidney disease?

In its early stages, kidney disease does not show symptoms, but instead is diagnosed through urine and blood tests. This is why it is important to be aware of the risk factors for kidney disease, which are diabetes, high blood pressure, cardiovascular disease, or genetic/family history of kidney disease.

How is kidney disease treated?

The earlier you are diagnosed, the better your chances of maintaining your kidney health. Treatment and management of kidney disease include medications to manage existing conditions and keep blood pressure and blood sugar levels healthy.
