Yes: A significant number of patients with rheumatoid arthritis will have a negative rheumatoid factor at the time of initial evaluation. There is no single blood test which allows one to make a definitive diagnosis of ra. The diagnosis of RA is made on the basis of clinical, historical and laboratory criteria.

YES!: Blood work is only one tool in the diagnosis and is not 100% accurate.
