Kidney Function
If you’ve been feeling more tired than usual, experiencing swelling in your legs or ankles, or noticing changes in how often you urinate, it could be worth checking in on your kidney health. Our Kidney Function Blood Test measures key markers - including creatinine, urea, and eGFR - to assess how well your kidneys are filtering waste from your body. These tests can help detect early signs of kidney stress, even before symptoms become obvious. Whether you’re managing an existing condition, taking certain medications, or just want peace of mind, this test gives you valuable insight into your kidney function and overall health.

Essential information about your test
What's in the test
What we measure:
- Creatinine - Creatinine is a waste product produced by muscles during everyday activity. It's released into the bloodstream and filtered out by the kidneys, making it a reliable indicator of how well your kidneys are functioning. Monitoring creatinine provides important insight into your body’s ability to clear waste effectively.
- Urea - Urea is formed when your body processes protein, with the liver breaking it down into this waste product. It’s then carried through the bloodstream to the kidneys, which remove it and pass it out in urine. Checking urea levels in the blood can offer useful clues about how well your kidneys are clearing waste and how efficiently your liver is handling protein metabolism. However, because your body can often compensate with just one healthy kidney, results may appear normal even if some kidney function is impaired.
- eGFR - Estimated glomerular filtration rate (eGFR) is a key measure of how efficiently your kidneys are filtering waste from your blood. It reflects the function of tiny filtering units in the kidneys called glomeruli. When these filters aren’t working properly, waste can build up in the body.
