What Is the RF Blood Test?

The Rheumatoid Factor (RF) test looks for specific antibodies produced by your immune system. High levels may suggest:

  • Rheumatoid arthritis
  • Other autoimmune inflammatory conditions
  • Ongoing or past infections

This test is a useful starting point if you’re noticing joint pain, stiffness in the mornings or swelling.

Why Choose Us for Your RF Test?

  • Fast results in around 15 minutes — ideal for peace of mind.
  • Pharmacist-led support to help explain what your result could mean.
  • No long waits — easy online booking.
  • Simple finger-prick sample taken in our Neath clinic.

What Your Result Means

RF levels can vary from person to person. A positive result doesn’t always mean rheumatoid arthritis, and a negative result doesn’t always rule it out. Your pharmacist will guide you on:

  • Whether further blood tests may help (e.g. CRP, ESR, Anti-CCP)
  • Whether to follow up with your GP or rheumatology services
  • Ways to support joint health while awaiting further assessment

Symptoms This Test Can Help Investigate

  • Morning stiffness lasting more than 30 minutes
  • Joint swelling or heat
  • Persistent joint pain
  • Fatigue or feeling generally unwell
  • Family history of autoimmune disease
