Why RF IgG Testing Important
RF antibody testing is often ordered by doctors, when any patient is suspected of having any form of arthritis. After evaluating the signs and symptoms of the patient, the RF serum testing result can play an important role in both diagnosis of rheumatoid arthritis and the disease prognosis. Actually RF testing result is usually regarded as an important indicator in the diagnosis of rheumatoid arthritis.
RA and RF
Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting primarily the joints and periarticular tissues. Several abnormal proteins circulate in the blood of RA patients. These proteins, because of their obvious correlation with the disease, became known as rheumatoid factor (RF). Rheumatoid factor is detected in 60-80% of cases of diagnosed rheumatoid arthritis. And, the higher the RF concentration in serum, the higher the possibility of the rheumatoid arthritis illness.
