What to know
When to collect your sample
The sample must be collected using the home collection kit* provided in the morning on a Monday - Thursday and returned on the same day. This ensures that your sample reaches the lab as soon as possible.
It is recommended that protein-heavy meals are avoided before collecting your sample, as high protein intake can affect these test results. This includes foods such as red meat, protein shakes, and supplements.
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
Who should be tested
This 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 infection.
You should be tested 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 infections
You have a kidney infection or a family history of one
You have kidney stones or a family history of them
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.
