After application of contrast media a rise in FT4 concentration was detected by use of the ultrafiltration method (Amicon) and the Dow-Lepetit method, especially after injection of Biliscopin, whereas the determination of FT4 concentration with the Amerlex method revealed a significant drop in FT4 concentration after contrast medium application. The results obtained with the Dow-Lepetit test have to be regarded as correct. The decrease detected by the Amerlex test is probably the result of a changed affinity of albumin to the labeled T4. Within 1 hr after application of contrast media blood for the determination of FT4 should not be collected.
使用造影剂后，通过超滤法（密理博）和道 - 勒佩蒂法检测到游离甲状腺素（FT4）浓度升高，尤其是在注射必利显影后；而采用阿美雷克法测定FT4浓度时，发现造影剂应用后FT4浓度显著下降。道 - 勒佩蒂试验所得结果应被视为正确的。阿美雷克试验检测到的下降可能是白蛋白与标记T4亲和力改变的结果。应用造影剂后1小时内不应采集用于测定FT4的血液。
