RA Factor (Rheumatoid Factor) Report Format — Sample & Free Download
An RA Factor (Rheumatoid Factor) test measures an autoantibody associated with rheumatoid arthritis and other autoimmune conditions, typically using a latex agglutination or turbidimetric method to give a quantitative titre.
This is a real report generated by Dr.Lably LIS — not a mockup.

When is it ordered?
- Investigating joint pain, swelling, or stiffness suggestive of rheumatoid arthritis
- Supporting a rheumatoid arthritis diagnosis alongside anti-CCP and clinical findings
- Evaluating suspected Sjögren syndrome or other autoimmune conditions
- Monitoring known autoimmune disease activity over time
Test details
- Specimen type
- Serum
- Turnaround time
- Same day (6 hours)
RA Factor (Rheumatoid Factor) report format breakdown
| Parameter | Unit | Normal range | What it means |
|---|---|---|---|
| Rheumatoid Factor | IU/mL | 0 - 15 | Elevated RF is associated with rheumatoid arthritis and other autoimmune conditions like Sjögren syndrome, but it can also be negative in some rheumatoid arthritis patients (seronegative RA) and mildly positive in healthy people, so it's interpreted alongside symptoms and other tests. |
Frequently asked questions
What does an RA Factor report format show?
The report lists a single Rheumatoid Factor result with unit, reference range, and status, plus a clinical notes section — as shown in the sample report above.
Do I need to fast before an RA Factor test?
No fasting or special preparation is needed for an RA Factor test.
Does a positive RA Factor mean I have rheumatoid arthritis?
Not necessarily — RF can be mildly elevated in healthy people and in other autoimmune or chronic conditions, so it's interpreted alongside symptoms, anti-CCP antibodies, and a doctor's clinical evaluation.
How is RA Factor different from Rheumatoid Factor IgM?
RA Factor (latex agglutination) measures total rheumatoid factor, while the Rheumatoid Factor IgM test specifically isolates the IgM isotype using a more precise quantitative method — see the related report format below.
