Psoriatic Arthritis Tests And Diagnosis
Erythrocyte sedimentation rate (sed rate or ESR) gives a rough idea of how much inflammation is in your body, which could be caused by psoriatic arthritis. But higher levels can come from other autoimmune diseases, an infection, a tumor, liver disease, or pregnancy, too.
X-Rays: These can show cartilage changes or bone injury that suggest arthritis in your spine and joints in your lower back and hands. Psoriatic Arthritis Tests usually looks different on X-rays than rheumatoid arthritis does.
Rheumatoid factor (RF) and anti-CCP antibody tests can rule out rheumatoid arthritis. People with that condition may have higher levels of these in their blood.More than half of people who have psoriatic arthritis with spine inflammation will have the genetic marker HLA-B27. You can get Psoriatic Arthritis Tests to find out if you do. People with psoriatic arthritis tests may have mild anemia, or not enough healthy red blood cells.
Bone Density: Because psoriatic arthritis may lead to bone loss, your doctor may want to measure your bone strength. You could be at risk for osteoporosis and fractures.
