Laboratory Testing for Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an autoimmune disease that can lead to the destruction of joints and loss of mobility.1,2

The intra-articular bone erosion usually occurs early during disease progression with 30 percent of RA patients having radiographically confirmed erosions at diagnosis and 70 percent three years later.2

Diagnosis: Early diagnosis of rheumatoid arthritis (RA) is important, because it has been recognized that early initiation of disease-suppressing therapy may improve clinical outcomes and reduce the accrual of joint damage and disability.1

TOPLAB’s testing menu offers a wide variety of tests for rheumatoid arthritis, designed to answer important clinical questions in the areas of screening, risk prediction, diagnosis, prognosis, monitoring.
