The development of a rapid, simple technique for the specific identification of urate crystals in gouty synovial fluid also resulted in the discovery of non-urate crystals in the affected joints of two patients (1). One case displayed the typical clinical features of acute gouty arthritis except for a normal serum urate level. This finding led us to examine microscopically numerous fluids from arthritic joints; we succeeded in finding non-urate crystals in six additional cases. Fluid from one of these patients, a known gouty arthritic, also showed urate crystals. The seven (non-gouty) patients showed clinical and roentgenographic similarities.
Crystals from six
