高通量ELISA法与电化学发光法测定血清癌胚抗原的比较

摘要

目的：探讨高通量ELISA法和电化学发光（ECLIA）法测定血清癌胚抗原（CEA）的可比性。方法分别用ECLIA法和高通量ELISA法对标本中的血清CEA浓度进行定量检测，并对检测结果进行比较。结果2种检测方法均能相对准确地反映血清中CEA浓度，检测结果差异无统计学意义（P＞0．05）。高通量ELISA法CEA检测结果在线性范围内与ECLIA法高度相关（r＝0．9228，P＜0．01）。结论高通量ELISA法可准确检测血清中CEA浓度。%Objective To compare the performance of high‐throughput ELISA and ECLIA in the determination of carcinoembry‐onic antigen (CEA) .Methods The CEA concentration of serum samples were respectively determinate by high‐throughput ELISA and ECLIA ,and the results were compared .Results Two kinds of detection methods could both accurately reflect the concentration of serum CEA .There was no significant difference between the results of two methods (P> 0 .05) .Within the linear range ,the CEA result of high‐throughput was correlate closely with that of ECLIA (r=0 .922 8 ,P<0 .01) .Conclusion High‐throughput ELISA can accurately detect the serum CEA concentration .
