  • Conjugated bilirubin

About this test

Conjugated (direct) bilirubin is a breakdown product of red blood cells that the liver processes and excretes in bile. Measuring it gives a focused check on liver function and how well your body is processing bile, rather than a full liver panel.

As a single-marker test, it places in the lower band for the number of biomarkers among the liver and kidney tests we track. On price, though, at £49 it costs well below the typical liver and kidney test of similar size in our tracking, and it can be done at home with a finger-prick kit as well as at a clinic.

The listing is clear about what you're buying: it sets out the biomarker, sample type, turnaround and collection options up front, though it doesn't describe the report format. On trust signals, Medichecks scores well, with a 4.5 Trustpilot rating from over 2,400 reviews, UKAS ISO 15189 accredited partner labs, doctor review built in as standard, and a trading history back to 2001. Collection convenience scores highly too, since you can do the whole thing at home if you prefer.

Who is it for?

This test suits you if you want a quick, low-cost check on one specific liver marker, for example to monitor bile processing over time or alongside advice from a healthcare provider, without paying for a full liver panel. It is not designed to give a complete picture of liver health on its own.

Because it can be done entirely at home with a finger-prick kit, it also suits people who would rather avoid a clinic visit or nurse appointment.

How it works

You can collect your own sample at home with a finger-prick kit, or choose an in-store clinic, home nurse visit or venous draw at a clinic instead. Once your sample reaches the lab it is tested for conjugated bilirubin, and a doctor reviews the result before your report is sent to you, typically within 3 days.

Pros & cons

Pros

  • Can be done entirely at home with a finger-prick kit, no clinic visit needed.
  • A doctor reviews your result before your report is sent.
  • Priced well below the typical liver and kidney test of similar size we track.
  • Results are typically back within 3 days.

Cons

  • Checks a single marker only, not a broader liver panel.
  • The provider does not describe what the final report looks like.

Our editorial score

Compare Health Test Score Low-cost single marker with at-home collection
Editorial confidence: 10.0/10

This blood test checks conjugated bilirubin, a liver function marker, for £49, and can be done with an at-home finger-prick kit or at a clinic. Every result is reviewed by a doctor, and against other liver and kidney tests of similar size that we track, it is priced well below the typical cost. The main caveat is that it checks only one marker rather than a full liver panel.
