A survey of 42 hospitals revealed that the frequency of synovial fluid analysis was low (mean 3.9 per month). The mean was skewed upward by a higher frequency in 3 teaching hospitals, such that the overall median was 1.5 per month, with 15 hospitals studying 1 or less per month. There did not appear to be any consensus regarding what constitutes a routine synovial fluid analysis. Technical errors occurred, including dilution with acetic acid for cell counts and inappropriate use of automated cell counters. Twenty-six laboratories studied 4 "unknown" fluids for crystals. In 50 opportunities to detect each crystal type, calcium pyrophosphate was detected only 6 times, and sodium urate was detected 39 times. The white blood cell count reported for a single fluid ranged from 2,467-12,000/mm3 (mean +/- SD 6,683 +/- 1,992). The proportion of neutrophils identified varied from 0-30% (mean +/- SD 13.8 +/- 8.6). The majority of respondents believed that training and reference materials related to synovial fluid analysis should be improved.
对42家医院的一项调查显示，滑液分析的频率较低（平均每月3.9次）。3家教学医院的较高频率使平均值向上偏移，因此总体中位数为每月1.5次，有15家医院每月检测1次或更少。对于什么构成常规滑液分析似乎没有达成共识。出现了技术错误，包括用乙酸稀释进行细胞计数以及自动细胞计数器使用不当。26个实验室研究了4份用于检测晶体的“未知”液体。在50次检测每种晶体类型的机会中，焦磷酸钙仅被检测到6次，尿酸钠被检测到39次。一份液体报告的白细胞计数范围为2467 - 12000/mm³（平均±标准差6683±1992）。鉴定出的中性粒细胞比例从0%到30%不等（平均±标准差13.8±8.6）。大多数受访者认为，与滑液分析相关的培训和参考资料应该得到改进。
