What is the rheumatoid factor blood test?
A rheumatoid factor blood test measures rheumatoid factor, an antibody the immune system can produce that is often present in rheumatoid arthritis. It is one piece of a wider picture rather than a diagnosis on its own. Leyton Pharmacy provides the RF blood test in London for £45, reviewed by a clinician.
Rheumatoid factor is an antibody that binds to other antibodies in the blood. It is found in many people with rheumatoid arthritis, and in some people with other autoimmune conditions. It can also appear in people with no joint problems at all, and it becomes more common with age.
That cuts both ways. A raised result does not confirm rheumatoid arthritis, and a normal result does not rule it out — a proportion of people with the condition never test positive. Your pharmacist at Leyton Pharmacy explains what your result adds to the picture and, where joint symptoms need a proper assessment, advises you to see your NHS GP.

Why people get a rheumatoid factor test
People book a rheumatoid factor test when joints are the problem. Anyone searching for an RF blood test near me usually has morning stiffness that lasts, swelling in the small joints of the hands or feet, or a family history of autoimmune conditions. Leyton Pharmacy runs the test for £45.
- Your fingers or wrists are stiff for a long stretch first thing in the morning.
- You have swelling or warmth in the small joints of your hands or feet.
- Joint pain has moved between different joints rather than staying in one place.
- Autoimmune conditions run in your family and you want a marker checked.
- You are gathering information before a GP appointment about joint symptoms.
- You have dry eyes and a dry mouth alongside joint symptoms.
- Your GP has already started looking into joint pain and you want to track markers between reviews.
Signs it may be worth testing
Joint symptoms worth investigating tend to follow a pattern: stiffness first thing that lasts, swelling in the small joints, and the same joints affected on both sides. Anyone weighing up a joint pain blood test in Leyton can use the list below as a prompt to check, not as a diagnosis.
Symptoms alone diagnose nothing, and neither does this test on its own. Rheumatoid factor is read alongside how your joints behave, other blood markers and a clinical examination — which is why anything persistent belongs in front of your GP.

Get your result explained
Your blood sample goes to a UKAS-accredited laboratory. Results are often back the same day, and a pharmacist explains what your rheumatoid factor result adds to the picture.
The appointment itself is straightforward. A trained member of our pharmacy team checks your details, asks a few questions about medicines, supplements and recent illness, then takes a small blood sample from a vein in your arm using a fresh, single-use needle. Most people describe a quick scratch and nothing more. You sit for a moment afterwards, we put a small dressing on, and you are on your way. There is no need to book time off — most people fit it around a normal day.
How to prepare for a rheumatoid factor test
There is no fasting before a rheumatoid factor blood test. Eat and drink as normal, and have a glass of water beforehand so the sample is easier to take. What helps most before an arthritis blood test in East London is arriving with a clear description of your joint symptoms.
- 1Eat and drink normally. Fasting is not required for rheumatoid factor.
- 2Drink water in the hour before your appointment. Good hydration makes the vein easier to find.
- 3Note down which joints are affected, how long morning stiffness lasts and when it started. That context shapes how the result is read.
- 4Tell the pharmacist about any recent infection, because some infections can produce a temporary raised result.
- 5Mention any autoimmune or liver condition already diagnosed, and any immune-suppressing medicines you take.
- 6If you have had rheumatoid factor tested before, bring the previous result so we can compare.
- 7Wear a top with sleeves that roll up easily, and bring a list of your medicines.
Understanding your results
Your rheumatoid factor result comes back as a number in international units alongside a reference range from the laboratory that ran it. Ranges differ between UKAS-accredited laboratories, and the number carries meaning only next to your symptoms. A pharmacist at Leyton Pharmacy talks you through yours.
This is a test where context does most of the work. A raised rheumatoid factor turns up in people with no joint disease, particularly as they get older, and a normal result does not rule rheumatoid arthritis out. It adds to a picture rather than settling it.
If your result is outside the laboratory range, the pharmacist explains what it commonly means, what usually happens next, and why joint symptoms need a proper clinical assessment. Diagnosing an autoimmune condition sits with a GP and, where needed, a rheumatologist — never with a single blood test.
Leyton Pharmacy does not replace your NHS GP. Where a result warrants a full clinical assessment we will tell you clearly, advise you to book with your GP practice, and give you a copy of your report to take along. A blood test is one piece of information, not a diagnosis.
Your rheumatoid factor reference range
| Measure | Typical adult range | Units |
|---|---|---|
| Rheumatoid factor (adults) | — | IU/mL |
Reference ranges are confirmed with our laboratory and printed on your own report. Your pharmacist will read yours with you at the pharmacy or over the phone, whichever suits you better.
