About this test

The CRP Blood Test measures high-sensitivity C-reactive protein, a protein produced by the liver in response to inflammation. It is commonly used as one factor, alongside others such as cholesterol and blood pressure, in assessing long-term heart disease risk, and can also flag general low-grade inflammation.

At £49, it costs about 45% less than the £89 median for the 26 similarly sized inflammation tests we track, though as a single-marker test its Clinical Depth score places it in the lower third of that wider set. There is no named comparison group of directly equivalent CRP-only tests in our data to benchmark it against more precisely.

It scores highly on Collection Convenience and Trust Signals, reflecting the choice of collection method and doctor review of every result, and its value for money score is strong given how far below the broader market median it sits.

Who is it for?

This suits you if you want a low-cost check of one inflammation marker, for example as part of tracking heart disease risk factors over time. If you want a broader inflammation or gut symptom workup rather than a single marker, Selph's Complete Gut Health Test & Symptom Screen or Calprotectin Test cover different, more specific ground.

How it works

You collect a sample at home with a finger-prick kit included in the price, or pay more for the Tasso EasyDraw device, a clinic visit or a nurse draw at home or work; a self-arranged venous draw is also included. A Selph doctor reviews your CRP result and provides a written report, typically within 1 to 2 days.

Pros & cons

Pros

  • About 45% below the £89 median price for similarly sized inflammation tests we track.
  • Four collection options, including a nurse visit at home or work.
  • Results reviewed by a doctor within 1 to 2 days.

Cons

  • A single-marker test, so it cannot show what is causing any raised result on its own.
  • CRP levels can be raised by recent infection, injury or exercise, which limits what one reading tells you.

Our editorial score

Compare Health Test Score Single CRP marker priced well below the market median
Editorial confidence: 10.0/10

This CRP test measures a single marker, high-sensitivity CRP, for £49, around 45% below the £89 median for the 26 similarly sized inflammation tests we track. Because it is a single-marker test, its clinical depth sits in the lower third of inflammation tests we track, even though CRP itself is a widely used marker. The main caveat is that CRP levels are affected by many things, including recent infection or exercise, so a raised result on its own says little without context.

Score breakdown

  • Clarity and documentation 9.0/10

    The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.

  • Clinical depth 6.4/10

    1 biomarkers, placing it in the 32nd percentile of inflammation tests we track.

  • Collection convenience 10.0/10

    A finger-prick sample you take at home; with a venous or clinic option as well; a home nurse visit is offered; results in around 2 days, well ahead of the inflammation norm of 4.

  • Results and follow-up 7.0/10

    Results are reviewed by a doctor; the provider does not describe the report format.

  • Trust signals 10.0/10

    Trustpilot 4.9 from 71,592 reviews; accredited lab (UKAS ISO 15189 partner labs (Inuvi, TDL)); CQC registered; doctor review as standard.

  • Value for money 8.7/10

    £49.00 against a median of £89.00 for the 26 similarly sized inflammation tests we track (-45%).
