Cardiff's private GP clinic offering expert kidney function checks. Convenient, confidential care in the heart of Cardiff from Mayfield Clinic’s private medical team.
Our Kidney Function Test measures how effectively your kidneys filter waste from your blood. It’s a clear, non-invasive way to check kidney health and detect potential issues early. The test is especially important for individuals with high blood pressure, diabetes, or those taking medications that may affect kidney function. Regular checks can help you maintain optimal health and avoid complications. If you’re searching for a kidney test UK options or a private kidney function test, this service offers a fast and convenient private pathway.

You don’t need to prepare for anything special beyond wearing comfortable clothing. Your GP will take a small blood sample and assess the results in the context of your medical history and current treatments. Our Cardiff private GP service prioritises clear communication, so you’ll receive straightforward explanations and practical next steps.
A standard blood test typically takes a few minutes to complete in-clinic, with follow-up results discussed at a later appointment. Urgent results are usually available the same day.
If abnormal results are found, your GP may recommend lifestyle changes, additional tests or referrals to a kidney specialist. We tailor follow-up to your needs.
