About this test

This test measures four markers used to assess kidney function: creatinine and eGFR, which reflect how well the kidneys are filtering waste from the blood, and sodium and urea, which relate to fluid balance and waste handling. These markers are commonly used to keep an early eye on kidney health, particularly if you have high blood pressure, diabetes, or a family history of kidney disease.

There is no named comparison group for this exact test in our data. Against the wider set of similarly sized liver and kidney tests we track, its £39 price is around 32% below the roughly £57 median, and it can be completed with an at-home finger-prick rather than a clinic visit, which is not always the case for tests in this category.

The scores reflect this combination of low price and convenience. Collection convenience scores the maximum, since the test can be done at home as well as via a venous draw, with a home nurse visit also offered and results within two days. Value for money scores well given the below-median price, and clinical depth scores solidly too, with four biomarkers placing it in the upper third of liver and kidney tests we track.

Who is it for?

This suits people who want a straightforward, low-cost check on kidney function, particularly if you have high blood pressure, diabetes, or a family history of kidney disease, or simply want to monitor your kidneys over time. The at-home finger-prick option makes it easy to repeat periodically.

We do not have comparable named tests in our data for this specific panel, so we cannot point to a cheaper or deeper alternative. If you have symptoms such as changes in urination, swelling or persistent fatigue, see your GP rather than relying on this test alone.

How it works

You can collect your own sample at home with a finger-prick kit, or choose a venous draw at a clinic or a home nurse visit. Once the sample reaches the lab, results are typically ready within two days, and every result is reviewed by a doctor as standard.

Pros & cons

Pros

  • Can be done at home with a finger-prick sample, no clinic visit required.
  • Priced around 32% below the median for similarly sized liver and kidney tests we track.
  • Fast turnaround of around two days.
  • Includes a doctor's review of your results as standard.

Cons

  • Covers only four markers, so it will not catch every kidney-related issue on its own.
  • No comparable peer tests in our data, so value cannot be checked against named competitors.
