The kidney function blood test is a crucial tool used by healthcare professionals to evaluate your kidneys' health and performance. These organs play a key role in filtering waste, balancing electrolytes, and regulating blood pressure. This test, essential for assessing overall health, influences treatment decisions and measures your 'estimated glomerular filtration rate' (eGFR) to gauge filtering capacity.

Symptoms like decreased appetite or nausea can indicate kidney issues, but not all deviations from the normal range require immediate intervention. Nevertheless, discussing your test results with your GP for a comprehensive evaluation is highly recommended.

Harness the power of One Day Tests for your renal health with our highly accurate blood test for kidney function. With rapid results from our CQC lab, comprehensive biomarker analysis, and the convenience of home testing, we provide the insights you need with the speed and accuracy you deserve.

About the Kidney Function Blood Test

The kidneys are pivotal in executing several critical functions, such as expelling waste products from the bloodstream, managing blood pressure, and ensuring the balance of electrolytes within the bloodstream. They are, however, susceptible to harm from infections, both inherited and acquired diseases, toxins, and certain medications. Often, kidney disease remains asymptomatic in its initial stages, making it challenging to detect early on.

This assessment determines your 'estimated glomerular filtration rate' or eGFR, a crucial indicator of your kidneys' efficiency. The eGFR calculation considers creatinine levels alongside factors like age, ethnicity, and gender, to gauge kidney performance.

An eGFR above 90 is deemed normal, while values above 60 are usually acceptable. An eGFR below 60 typically indicates kidney disease. Although kidney disease can exist with a normal eGFR, a standard result provides peace of mind. It's important to note that eGFR can naturally decrease with age, so a lower score might not always signal a significant health issue. Understanding your eGFR is vital as it can influence medication choices and dosages, as well as inform strategies for managing cardiovascular risk and blood pressure.

SPECIAL INSTRUCTIONS

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Kidney Function Blood Test.

Please ensure you’re well-hydrated before taking this test.

If you have recently taken the antibiotic trimethoprim (usually for a urinary tract infection), delay taking this test for a couple of weeks.

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

Drink plenty of water about an hour before the appointment.
Avoid coffee/tea/energy drinks. Water is good!
That’s it! We’ll do the rest.

Home test kit for Kidney Function Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

Full printed instructions will arrive with your kit - please read them carefully.
Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.

FREQUENTLY ASKED QUESTIONS

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

What does it mean if my eGFR is low?

A low eGFR can occur for lots of reasons. eGFR can fall in the short term due to acute illnesses, particularly illnesses that result in dehydration such as diarrhoea and vomiting, or sometimes due to using some medications (for example, the antibiotic trimethoprim can cause a falsely low eGFR). A persistently low eGFR may represent a gradual decline in kidney function as part of ageing or underlying kidney disease. So, a low eGFR is normally repeated and, if it remains low, further investigations are usually started.

What are common causes of kidney diseases?

There are numerous types of kidney disease but common causes of kidney disease are poorly controlled diabetes and high blood pressure.

Can this test tell which kidney has a problem?

No, this test provides an overall assessment of kidney function. Often, if there is a problem with one kidney, the other kidney can adequately compensate. For example, people who have donated a kidney to someone else often have healthy kidney function.

WHY TAKE THE TEST?

Hi, I am Nader Eldarf, I am a Biomedical Scientist in our laboratory and here is why it's important to take this test.

As part of an overall assessment of your health
To check for unrecognised kidney disease
To monitor kidney function if you already have a condition that might harm the kidneys, such as diabetes

IS THIS TEST RIGHT FOR YOU?

Hi, I am Sandeep Patel, I am the Laboratory Director at One Day Tests. Here are the symptoms that you may wish to address with this test.

Given the crucial roles the kidneys play in maintaining overall health, incorporating a kidney blood test into any general health assessment proves to be immensely beneficial.

Kidney disease frequently presents no symptoms during its initial stages, making early detection challenging. This test, however, offers a proactive means to identify any potential issues at an early juncture.

This examination is particularly pertinent for individuals with a family history of kidney disease, providing an essential tool for early intervention and management.
