Is it possible to have psoriatic arthritis and test negative for arthritis?

Is it possible to have psoriatic arthritis and test negative for arthritis?

Psoriatic arthritis: Hi Sharon, Psoriatic arthritis is under the umbrella of spondylo-arthritis. This group of arthritis has a genetic test for Human Leukocyte Antigen B27 (HLA B27). A positive test means HLA-B27 is present. About 50% of patients with psoriatic arthritis test positive for HLA B27, therefore a negative test does not exclude the diagnosis. I hope that is helpful. Thank you, Nisha ...Read more

Mild Psoriasis sufferer, chronic pain right forarm & elbow. Blood tests 80 titre ana, positive anticentromere. Psoriatic arthritis or scleroderma?

Symptoms have to be put into context and better described than elbow and forearm pain. This one you should see a rheumatologist about. Dermatology would be useful as well. Best of luck! ...Read more
