Seronegative and Seropositive Rheumatoid Arthritis (RA) | Rheumatologist Dr. Micah Yu

Seropositive rheumatoid arthritis and seronegative rheumatoid arthritis are two different classifications of rheumatoid arthritis (RA) based on certain blood tests. Seropositive RA is characterized by the presence of specific autoantibodies in the blood, particularly rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies. These antibodies indicate an immune response that is often more aggressive and may lead to more severe joint damage in some cases.

On the other hand, seronegative RA refers to cases where these autoantibodies are not detected in the blood. While the absence of these antibodies might suggest a milder form of the disease, seronegative RA can still cause significant joint inflammation and damage. It's important to note that the absence of these antibodies doesn't necessarily mean the condition is less severe; it's just a different subset of RA.

The distinction between the two classifications helps healthcare providers tailor treatment plans and predict potential disease progression in some cases, but the overall management approach remains centered on improving the patient's quality of life. Don't forget to comment your thoughts about Seronegative RA and seropositive RA.
