The diagnosis of joint infections is an inexact science using combinations of blood inflammatory markers and microscopy, culture, and sensitivity of synovial fluid (SF). There is potential for small molecule metabolites in infected SF to act as infection markers that could improve accuracy and speed of detection. The objective of this study was to use nuclear magnetic resonance (NMR) spectroscopy to identify small molecule differences between infected and noninfected human SF.

受感染和未受感染的滑液之间的差异。

关节感染的诊断是一门不精确的科学，结合了血液炎症标志物和显微镜检查，培养以及滑液敏感性（SF）。被感染的SF中的小分子代谢物有可能充当感染标记，可以提高检测的准确性和速度。这项研究的目的是使用核磁共振（NMR）光谱法确定感染和未感染的人SF之间的小分子差异。
