近日,国际杂志 《Clinical Chemistry》上在线发表一项关于美国和欧洲多中心前瞻性研究新型敏感全自动免疫降钙素测定的分析性能和临床验证的研究。

这是一项针对9个美国和欧洲转诊机构进行的基础血清CT浓度的多中心前瞻性研究。本研究的目的是验证和证明新型电化学发光免疫测定(ECLIA)用于测定甲状腺髓样癌(MTC)患者和甲状腺不同疾病患者血清降钙素(CT)以及钙稳态的临床相关性。此外,经刺激的CT浓度通过在50名健康志愿者静脉内给予钙(2.5mg/kg体重)后测量。

研究总共包括1929名患者和健康对照。ECLIA的空白,检测和定量限制分别为0.3,0.51 ng/L。最高的外部和内部变异系数分别为7.4%(CT浓度,0.8 ng/L)和7.0%(1.1 ng/L)。783例健康对照组血清CT浓度中位数(间隔)女性和男性的分别为0.8ng/L<0.5-12.7)和3ng/L<0.5-18)(分别为97.5百分位数,6.811.6ng/L)。女性/男性的诊断敏感性和特异性分别为100/97.1%和96.2/96.4%。原发性甲状旁腺功能亢进,肾衰竭和神经内分泌肿瘤患者CT浓度大于第97.5个百分位点(男性/女性)分别在33/ 4.7%,18.5/ 10%和8.3/ 12%。在钙治疗(男性和女性分别为161.7111.8 ng/l;P < 0.001)后,血清CT浓度达到2分钟

研究发现,在非MTC患者中,其分析性能好,个体差异性低,混杂因素影响较小,表明该检测方法具有临床应用价值。钙刺激的CT结果表明,由于个体差异性较小,测试适用性很好。
