About This Test
About This Test
Symptoms
Your kidneys are responsible for filtering your blood and removing waste products through your urine. They also manage water retention and control ion concentrations and the acid balance in your blood.
Symptoms of acute kidney failure may include:
Chronic fatigue
Urinating less frequently or producing a reduced volume of urine
Nausea
Irregular heartbeat
Shortness of breath
Seizures
Fluid retention
Swelling in the legs, ankles, and feet
Chest pain
When to test
This test will indicate how your kidneys are performing by measuring levels of urea, creatinine, and eGFR. High levels of urea, creatinine and a low eGFR can indicate acute or chronic kidney disease.
You should take the test if:
You have a high protein diet
You have used or are using performance enhancing drugs
You are taking anti-inflammatory medication
You suffer from high blood pressure
You suffer from diabetes
You have suffered an acute injury
You have persistent urinary tract diseases
You have a kidney disease or a family history of one
You have kidney stones or a family history of them
The sample must be collected in the morning, on Monday - Friday and returned on the same day.
It is recommended that protein-heavy meals are avoided before taking this test, as high protein intake can affect these test results. This includes foods such as red meat, protein shakes and supplements.
What's measured
Urea
Urea is a waste product formed from the breakdown of proteins and is passed out in your urine. A high level of urea ('uremia') indicates that the kidneys may not function optimally or that you are dehydrated.
Creatinine
Creatinine is a waste product made by your muscles and dietary protein. Creatinine passes into the bloodstream and is usually passed out in urine. A high blood level of creatinine indicates that the kidneys may not be working properly.
eGFR (Estimated Glomerular Filtration Rate)
eGFR (estimated glomerular filtration rate) is a calculation that determines how well your kidneys are filtering blood.
