About this test

Rheumatoid factor is an antibody found at raised levels in a majority of people with rheumatoid arthritis, but the provider's own description notes it also shows up in other conditions and in a small percentage of healthy people, so a raised result is not on its own conclusive.

It scores well for value for money, since £72.25 sits below the median price we see for similarly sized inflammation and autoimmunity tests, and for clarity, since the listing sets out the biomarker, turnaround and collection options. Clinical depth is more middling, since a single marker sits around the middle of the inflammation tests we track, and collection convenience is limited to a venous draw at a clinic or a nurse home visit.

Results are reviewed by a doctor and come back within 5 days. Blue Horizon Medicals works with UKAS ISO 15189 partner labs and has traded since 2009.

Who is it for?

This suits people who, alongside a GP, want a rheumatoid factor result as one part of investigating joint symptoms, rather than a stand-alone answer, since the marker also appears in other conditions and in some healthy people. If you have joint symptoms, discuss them with a GP who can advise on the right combination of tests.

We do not have a directly comparable named rheumatoid factor test from another provider in our data, so we cannot point you to a cheaper or broader named alternative.

How it works

This is a blood test taken by venous draw, either at a clinic or with a nurse home visit; there is no at-home collection option. The sample is analysed for rheumatoid factor, with results back within 5 days and reviewed by a doctor before you receive them.
