Understanding Psoriatic Arthritis: Symptoms, Diagnosis, and Management

Diagnosis of Psoriatic Arthritis

Diagnosing PsA can be challenging because its symptoms overlap with other forms of arthritis. There is no single test for PsA, so diagnosis typically involves a combination of:

• Medical History: A detailed medical history helps the physician understand the patient’s symptoms and any history of psoriasis.
• Physical Examination: A physical exam focuses on joint inflammation, skin lesions, and nail changes.
• Blood Tests: Blood tests are used to rule out other forms of arthritis, such as rheumatoid arthritis, and to assess inflammation markers. However, no specific blood test can confirm PsA.
• Imaging Studies: X-rays or MRI scans can be used to detect joint damage and inflammation, helping to differentiate PsA from other types of arthritis.
