Kidney Function Blood Test

The two kidneys act as a filter for the blood. They retain the products that the body needs and filter out waste products into the bladder as urine. Blood tests that measure how well the kidneys are working look at a number of elements - most commonly the waste products urea and creatinine as well as the filtration rate and the important salts, potassium and sodium.

A kidney function test is an important component of our patient health screens. Your doctor may recommend a health screen to investigate potential reasons as to why you are not feeling yourself. Do not worry about determining for yourself which if any blood test you need. This is something that your doctor will be able to determine and explain during your consultation.

All our blood tests are available same day with some of the fastest results in London. One of our doctors will take the time to explain to you what your test results mean and put in place any appropriate next steps based on those results.

This is only a small sample of the many blood tests which DocTap provide. Our expert doctors can advise you during your consultation on the most appropriate tests for your condition. View all blood tests.

* Please note that the lab results are estimates and can vary. Tests taken after 1pm will be classified as the following day for timing purposes. You will receive a written analysis of your results within 1 working day of them being available from the laboratory. It is often possible for the doctor who reviews your results to be the same doctor who requested them. This is considered medical best practice but will add an additional 1 working day to the timings. If you have multiple tests then we shall wait to report on them together unless the first results highlight any reason for concern. Sometimes the preliminary results will determine that additional tests need to be carried out on your sample. If this is the case then your results will take longer. There is no additional charge for this service.

Why Choose DocTap?

DocTap seek to provide the most convenient, fastest, effective and best value private blood testing service in London. With 9 blood test centres across London and same day appointments available 7 days a week, it has never been easier to book a kidney function test. We are proud to partner with The Doctors Laboratory (TDL) which has a worldwide reputation for excellence.

Unlike many organisations, you will see a UK accredited GP who will be able to offer their expert option on what test is most appropriate for you. Your results will also be accompanied by a written analysis of what they mean and what your doctor advises you to do next. Should additional treatment be required, or if you simply wish to discuss the results in more detail, then you can book a 15 minute follow up consultation for only £25. This can either be at any DocTap clinic or over the phone. When booking your follow up consultation you can request to see you original doctor if you wish (subject to their availability).

Should you require a full consulation before deciding to have a kidney function test then there may be insufficient time to also take a blood sample in the appointment. In that case you can choose to either go to our walk in laboratory by Oxford Street (£15 phlebotomy fee applies) or to make a second appointment for the doctor to take the bloods.

What does a Kidney Function Test measure?

As well as filtration, the kidneys have a vital role in retaining salt and water. This in turn affects blood pressure. 

Blood tests that measure how well the kidneys are working look at a number of elements:

What other kidney tests might I need?

These blood tests will not tell the Doctor exactly what the problem is - only that there is a problem. Further tests such as urine testing, ultrasound scans, special kidney function scans, and kidney biopsies may be necessary to diagnose the cause.
