What is rheumatoid arthritis zero positive? - KeithD - 04-02-2023
Rheumatoid arthritis zero positive refers to a person who has no evidence of rheumatoid factor (RF) in their blood but still has symptoms consistent with rheumatoid arthritis (RA). Rheumatoid factor is a type of protein that is often present in the blood of people with RA, but some individuals with RA may test negative for it. The diagnosis of RA is based on a combination of clinical symptoms, imaging results, and laboratory tests, and a negative RF test does not rule out a diagnosis of RA.
