Is There A Blood Test for Psoriatic Arthritis?

  1. Joint fluid test (laboratory test). In this test, a small sample of fluid is taken from the affected joint (typically from the affected knee) which then will be analyzed to determine whether the problem is caused by gout or psoriatic arthritis.
  2. Imaging tests (such as with MRI ‘Magnetic Resonance Imaging’ and X-rays). These tests are usually needed to help provide detailed images of the affected joints.

It may take some time for your doctor to make the diagnosis. But if you joints are affected along with unusual symptoms that affect your nails and skin, a concrete diagnosis can be made easier.

Are there any crucial things you need to prepare before taking the test?

You tend to first discuss your symptoms /signs with your GP or family doctor. Then she /he can refer you to a specialist or rheumatologist.

Before making an appointment with a specialist, it’s better to prepare the answers of the following checklists:

  1. About the symptoms of the problem that you have – and whether there are certain activities /positions that make the symptoms get worse!
  2. Do you have a family history of the problem (psoriasis or/and psoriatic arthritis)?
  3. Are you taking medicines /supplements?

Since it’s not always easy to remember anything, it’s better to invite your parent /family members or a friend when you see a specialist.
