How is GCA diagnosed?
Often, a biopsy of the temporal artery is needed to confirm the diagnosis. For this biopsy, a small piece of the temporal artery is removed and looked at under a microscope. Your doctor may also order blood tests to check for inflammation of the arteries and to rule out other conditions.
How is PMR diagnosed?
Your doctor will likely perform a physical exam and ask about your symptoms. He or she may order a blood test, which can help detect inflammation of your arteries and check your blood count. Your doctor may also order a muscle biopsy to check for PMR.
