How do I know if there is a tophi?

Topaths can be diagnosed by B-ultrasound examination, blood uric acid determination, synovial fluid examination, etc. The specific analysis is as follows:

1. B-ultrasound examination

can observe whether there is abnormality in the affected joint part through B-ultrasound examination. If "double track sign" is found in B-ultrasound examination, it can be preliminarily diagnosed at this time.

2. Blood uric acid determination

can also be checked by blood uric acid determination. If the patient's blood uric acid index is abnormal, it can further assist in the diagnosis of tophith.

3. Synovial fluid examination

can also be examined by puncture synovial fluid examination. If urate crystals are found, it can be definitely diagnosed at this time.
