Not unusual : Many patients with psoriatic arthritis (approximtely 50%) will have either normal or near normal ESR and or CRP levels (inflammatory markers). Patients with psoriatic arthritis will usually have negative rheumatoid factors and ccp antibodies and antinuclear factors.

Psoriatric Arthritis: There is no lab test specifically for psoriatic arthritis. Patients thought to have psoriatic arthritis often will have labs drawn to make sure they do not have rheumatoid arthritis or gout. Patients with psoriatic arthritis will often have an elevated inflammatory marker known as the sedimentation rate (ESR) but a negative rheumatoid factor (rf).
