【摘要】 目的探讨脂血标本对时间分辨荧光免疫分析法检测游离雌三醇水平的影响。方法收集男性呈正常和乳糜样外观的不同水平脂血标本,与不同水平的游离雌三醇定值血清混匀,制成混合血清,用时间分辨荧光分析法测定其游离雌三醇水平以评价不同乳糜样和正常外观脂血标本对游离雌三醇水平的影响。结果对于乳糜样外观标本,轻度脂血可使游离雌三醇水平增高,中度及高度脂血则使游离雌三醇水平降低,且对游离雌三醇水平的影响十分接近。外观正常的中度脂血对游离雌三醇水平无显著干扰。结论乳糜样外观脂血对时间分辨荧光分析法测定游离雌三醇存在不同的影响,进而影响唐氏筛查的准确度。更多还原

【Abstract】 Objective To investigate the effect of different degree lipidemia on time-resolved fluoroimmunoassay(TRFIA)for determination of unconjugated estriol(uE3).Methods Mixed serum was prepared by collecting different levels of lipidemia samples which were normal and chylous appearance from male and by mixing with definite value serum of uE3.The levels of uE3 in the samples were measured by TRFIA and the effect of lipidemia on TRFIA for determination of uE3 was evaluated.Results For the appearance of chylous specimens,mild lipidemia increased uE3,mid-or hiper-lipidemia samples reduced uE3 and the effect of both was considerable.Conclusion The chylous lipidemia has variant degree of influence to TRFIA for determination of uE3,then the results effect accuracy of Down′s screening.更多还原
