Liver and Kidney Function Test

£49.00

This comprehensive test assesses the health of your liver and kidneys — two vital organs responsible for detoxifying your body, balancing fluids, and filtering waste.

It measures key biomarkers including:

  • Liver markers: ALT, AST, ALP, Total Bilirubin, Albumin, Total Protein, GGT and Globulin — helping detect liver inflammation, damage, or bile flow issues.
  • Kidney markers: Urea, Creatinine, and eGFR — used to evaluate how well your kidneys are filtering waste.

Ideal for monitoring ongoing health, managing long-term conditions, or checking for early signs of organ dysfunction.

This test can be done on a finger-prick sample as well as a phlebotomy sample.

What can I expect from Liver and Kidney Function Test?

Liver Function Tests are a group of blood tests that are used to check how well your liver is working. The liver is an important organ that helps with digestion, filters toxins from the blood, and stores energy.

These tests can help to diagnose liver diseases, monitor the progression of liver conditions, and check for any potential side effects of certain medications.

The tests measure levels of different enzymes, proteins, and other substances in the blood that can indicate how well the liver is functioning. Abnormal results from these tests can indicate liver damage, inflammation, or other problems. 

The kidney function test measures various parameters such as creatinine, blood urea nitrogen (BUN), and estimated glomerular filtration rate (eGFR). These parameters help in evaluating the filtration rate and waste removal, in the kidneys.

You may have several reasons for taking this test including monitoring kidney health, diagnosing kidney disease and as part of an assessment of your overall health. It is also necessary to check when starting certain medications and to monitor the effects some medications may have on your liver and kidneys

What gets tested?

Liver Function (8 health indicators)

The liver is responsible for many of the body's essential functions such as regulating blood sugar levels, fighting infections and detoxifying your blood. Good liver function is vital to your overall health and wellbeing.

Kidney Function (4 health indicators)

Your kidneys play a vital role in keeping your body functioning including the removal of waste products, releasing hormones to regulate blood pressure and controlling the production of red blood cells. A healthy kidney function is vital to your overall health and wellbeing.

How do I read my results?

Laboratory results are provided with reference ranges which are based on the normal test results of a large group of healthy people from the same age group and gender as yourself.

Sometimes, healthy people get results outside the reference range, while people with health problems can have results in the normal range. If your results fall outside the reference range, or if you have symptoms despite a normal result, you may require more testing or wish to discuss the result with your GP.

For simplicity, we provided your results graphically, so they are easy to understand. Any result flagged amber is outside of the standard range. Normal results are in green.

If you see ‘invalid result’ on any of your report pages, it’s nothing to worry about. Please call our Customer Service team on 020 7183 3718 and if required we will be able to arrange another blood test appointment free of charge or post you a home testing kit which you can post back to our laboratory
