General Information About the Test
Test Process and Preparation
No. Although an elevated Rheumatoid Factor is seen in a large portion of rheumatoid arthritis patients, it can also be positive due to chronic infections (hepatitis, tuberculosis), advancing age, and sometimes even in completely healthy individuals. Therefore, it must be supported by the Anti-CCP test and clinical examination for a diagnosis.
In about 20% of patients, although Rheumatoid Arthritis is clinically present, the RF test in the blood may be negative (normal). This condition is called "Seronegative Rheumatoid Arthritis."
Fasting is not mandatory for the RF test. It can be performed on a blood sample taken at any time of the day.
