What it checks
What does a CRP blood test check?
CRP (C-reactive protein) is a marker of inflammation. Our packages use a high-sensitivity version — hs-CRP — which can measure lower levels of inflammation than a standard CRP test. This makes it useful for cardiovascular risk awareness when interpreted in context, although levels can also rise with infection, injury or recent intense exercise.
hs-CRP is included in our Optimal Health Check and our Men’s and Women’s Cancer Marker Health Checks. It is not currently included in our Essential or Advanced Health Checks.

Which packages include it
hs-CRP testing in our packages
Three of our five packages include hs-CRP. It is not included in our Essential or Advanced Health Checks.
Optimal
£189
Includes hs-CRP alongside thyroid function, full lipid profile, full blood count and our most comprehensive standard health check.
Men’s Cancer Marker Check
£249
Includes hs-CRP alongside PSA prostate testing, FIT bowel screening and a 47-marker panel.
Women’s Cancer Marker Check
£249
Includes hs-CRP alongside CA125 testing, FIT bowel screening and a 47-marker panel.
Single blood tests start from £99, with some specialist tests priced higher. For better value, many patients choose a health check package instead, which includes a broader blood panel, on-the-day checks and a clearer picture of their results.
What results may indicate
Understanding hs-CRP results
hs-CRP is a non-specific marker of inflammation. Results need careful interpretation in context, since many short-term factors can affect levels.
What CRP measures
CRP (C-reactive protein) is a marker of inflammation produced by the liver. Levels rise when there is inflammation in the body — from short-term causes such as infection or injury, or longer-term low-grade inflammation.
Why hs-CRP rather than standard CRP
High-sensitivity CRP (hs-CRP) measures the same protein but at much lower concentrations than standard CRP. This makes it more useful for assessing low-grade chronic inflammation, which has been studied in the context of cardiovascular risk awareness.
What raised hs-CRP can indicate
Raised hs-CRP can flag patterns linked to inflammation from many causes: a recent infection, injury, intense exercise, smoking, obesity, or chronic conditions. Because it is non-specific, hs-CRP is most useful when read alongside other markers and in context with lifestyle, family history and other clinical information.
When the test is most useful
hs-CRP is generally not useful as a standalone test. It supports broader assessment of inflammation and cardiovascular risk, and is most informative as part of a wider health screening package that also covers cholesterol, blood pressure, lifestyle and other markers.
hs-CRP testing is for screening and risk awareness, not diagnosis. Raised levels can have many non-serious causes including recent infection or injury. If results suggest medical follow-up — or if you have current symptoms — please speak to your GP.
