摘要 目的采用免疫化学发光法(CLIA)、酶联免疫吸附法(ELISA)检测25羟维生素D[25(OH)D3]在常见甲状腺相关疾病患者外周血中的表达水平,并对两种检测方法的结果进行比较。方法应用CLIA及ELISA法同时测定97例健康人群(NC组)、57例Graves病(GD组)、69例桥本甲状腺炎(HT组)及73例亚急性甲状腺炎(SAT组)患者血清中的25(OH)D3水平,同时检测四组人群中的血钙、血磷水平及甲状腺功能相关指标。结果 CLIA法及ELISA法检测结果均显示,四组甲状腺相关疾病患者血清间25(OH)D3水平差异存在统计学意义,两两组间比较示NC组血清中25(OH)D3的水平最高(63.46±17.28 ELISA法及57.28±16.36 CLIA法,P<0.05),GD组大于HT、SAT组(47.26±13.63 ELISA法及46.86±11.64CLIA法,P<0.05)。ELISA法检测的25(OH)D3值高于CLIA法,但差异无统计学意义(P>0.05)。GD及HT组中,25(OH)D3与血清游离三碘甲状腺原氨酸(FT3)及游离甲状腺素(FT4)存在正相关性与促甲状腺激素(TSH)及抗甲状腺过氧化物酶体(TPOAb)存在负性相关,而NC组及SAT组中25(OH)D3与甲状腺功能指标间不相关。结论与健康人群相比,甲状腺相关疾病各组患者血清中25(OH)D3水平明显降低,CLIA法及ELISA法检测25(OH)D3结果相关系数高,均适用于临床检测外中血中25(OH)D3。
