ABSTRACT:
The present invention relates to a method aiding in the assessment of rheumatoid arthritis. The method especially is used in assessing the absence or presence of rheumatoid arthritis in vitro. It can be best practiced by analyzing biochemical markers, comprising measuring in a sample the concentration of anti-CCP and serum amyloid A and correlating the concentrations determined to the absence or presence of rheumatoid arthritis. To further improve the assessment of RA in a method of this invention the level of one or more additional marker may be determined together with anti-CCP and serum amyloid A and be correlated to the absence or presence of RA. The invention also relates to the use of a marker panel comprising anti-CCP and serum amyloid A in the diagnosis of rheumatoid arthritis and it teaches a kit for performing the method of the invention.
