RA Factor (Turbidimetric) Test

The RA Factor (Turbidimetric) Test measures the level of rheumatoid factor (RF) in the blood. Rheumatoid factor is an autoantibody produced by the immune system that can attack healthy joint tissues, leading to chronic inflammation, pain, and joint damage.

This test is primarily used for:

• Diagnosis of Rheumatoid Arthritis (RA)

• Screening of autoimmune disorders

• Monitoring disease progression and treatment effectiveness

High levels of rheumatoid factor are most commonly associated with:

• Rheumatoid Arthritis

• Sjögren’s Syndrome

• Systemic Lupus Erythematosus

• Chronic infections and liver disease

However, it is important to note that:

• Some healthy individuals may also show low RF levels

• Some people with autoimmune diseases may test RF negative, especially during early stages

Because of this, the RA Factor test is usually interpreted along with:

• Anti-CCP (if recommended)

• ESR

• hs-CRP

• Clinical symptoms and imaging

This test plays a crucial role in early detection of autoimmune arthritis, helping doctors initiate timely treatment to prevent irreversible joint damage, deformities, and disability.

This is a turbidimetric blood test used to measure rheumatoid factor (RF), an autoantibody produced by the immune system that mistakenly attacks healthy tissues.
