Kidney Function Blood Test

Kidney Function Blood Test: Comprehensive Assessment for Renal Health

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.

How Many Attempts to Collect the Blood Sample?

  • Please take note of the following in our Phlebotomy policy: Each staff member is permitted only two attempts to collect a blood sample from a patient.
  • However, if a patient's veins are difficult to access, another phlebotomist may take over the collection, or the patient will be rebooked to be attended by our Senior Registered Manager, with the patient's consent.
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.

Online Booking System

We provide a same-day blood result service for some blood tests (Monday – Friday, excluding Bank Holidays). A £ 35 fee for Phlebotomy + Courier charge will be applied for all Bloods.

Frequently Asked Questions 

  1. What is a blood test for kidney function?
A Kidney Function Blood Test is a test done in a lab that checks how well your kidneys are working by looking for certain markers in your blood that show how well your kidneys are doing their job.
  1. What markers are looked at in a blood test for kidney function?
The test usually looks at things like creatinine, urea (blood urea nitrogen), and estimated glomerular filtration rate (eGFR) to see how well your kidneys are filtering.
  1. Can medications change the results of blood tests for kidney function?
Yes. Some medications, like pain relievers, blood pressure medications, and antibiotics, can change kidney markers. Always tell the doctor about any vitamins or medicines you are taking.
  1. Is a blood test for kidney function a good way to check your health on a regular basis?
Yes. Kidney function tests are often part of general health check-ups, especially for people over 40 or those who have high blood pressure or diabetes.
  1. Can there be kidney problems even if you don't notice any symptoms?
Yes. Early kidney problems don't always show up with clear signs, which is why blood tests are important for finding them early and stopping them from getting worse.
  1. Is this test helpful for keeping an eye on chronic kidney disease?
Of course. Kidney function blood tests are very important for keeping an eye on the progress of a disease and seeing how well treatment plans are working over time.
