Tests and diagnosis

By Mayo Clinic Staff

Pseudogout signs and symptoms can mimic those of gout and other types of arthritis, so lab and imaging tests are usually necessary to confirm a diagnosis.

Lab tests

Blood tests can check for problems with your thyroid and parathyroid glands, as well as for a variety of mineral imbalances that have been linked to pseudogout. Your doctor may also use a needle to withdraw a sample of the fluid within your affected joint. This fluid can be tested for the presence of crystals.

Imaging tests

X-rays of your affected joint often can reveal evidence of joint damage, along with crystal deposits in the joint's cartilage.
