Comparative Study Between Immunoturbidimetric and Latex Agglutination Methods for the Detection of Rheumatoid Factor
Jornal Brasileiro de Patologia e Medicina Laboratorial(2013)
摘要
Introduction:The rheumatoid factor (RF) is the most common antibody found in patients with rheumatoid arthritis.It is an inflammatory chronic disease characterized by articular involvement, inflammation of synovial fluid, tissue infiltration by leucocytes and joint destruction, which ultimately determine articular deformities.The rheumatoid factor is found in 70%-80% of the adult population and in 10% of the young population.Objective: The aim of this research was to compare immunoturbidimetric and latex agglutination methods for the detection of RF in serum.Results: The immunoturbidimetric method displayed sensitivity (95.2%), specificity (89.4%) and high positive correlation (R 2 = 0,8077) with the latex agglutination method in positive serum samples.Conclusion: The study allowed to demonstrate that both immunoturbidimetric and latex agglutination methods equally discriminate between negative and positive serum samples for RF.
