Tests & Diagnosis
A diagnosis of chondrocalcinosis 2 is often suspected based on characteristic signs and symptoms. Specialized testing, such as synovial fluid analysis, can then be ordered to confirm the diagnosis. In synovial fluid analysis, a small sample of the fluid that surrounds affected joints is removed and examined to determine if calcium pyrophosphate dihydrate crystals are present. In most cases, x-rays can be used to identify calcium deposits in the cartilage of joints.
