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 withdraw a sample of the fluid from your affected joint with a needle to test for the presence of crystals.

Imaging tests

X-rays of your affected joint often can reveal joint damage and crystal deposits in the joint's cartilage.
