简介：摘要目的鼻咽癌病人多项免疫功能及EB病毒PCR检测的综合研究。方法本文选取我院于2014年04月~2015年04月收治的18例鼻咽癌患者，对其免疫功能及其EB病毒PCR检测方式之间存在的关系加以有效研究和探讨，进一步对鼻咽癌患者血液中EB病毒抗体、其他氧化物活性等多项指标值进行测定。结果鼻咽癌患者患者的锌离子、铜离子、钙离子微量元素指标大小结果分别是（16.09±5.17）umol/l、（17.40±5.13）umol/l、（2.19±0.17）umol/l，和正常人群的三项微量元素指标大小结果对比存在显著性差异（P<0.05），具有统计学意义。结论鼻咽癌患者采用通过开展免疫功能及其EB病毒PCR检测方式的有效探索，发现鼻咽癌患者血清中含有多种微量元素及其EB病毒抗体等物质成分，这对于通过血液指标含量来测定鼻咽癌疾病奠定了坚实的条件。
