In 250 cases of DTC patients, follow-up TgAb positive, TgAb negative group TgAb, Tg scattered point diagram do not show the Tg concentration increases with the concentration of TgAb linear trend. Tg, TgAb correlation analysis showed TgAb positive group, however, negative group or all of the 250 patients with DTC, Tg, TgAb concentration has no correlation. Therefore, you can't use the TgAb concentration prediction of Tg interference degree [7 ]. This study concluded that although other authors with the same conclusion, but we use the research methods and other authors of different, TgAb is endogenous autoantibodies, interference of Tg autoantibodies in the serum of Tg patients. Stanojevic.M 2009 were collected from 71 DTC patients of postoperative for at least 6 weeks, 131I removal before treatment to the patients, and the mapping of TgAb-Tg concentration diagram. At this time, because the operation is released into the blood in the Tg has not yet been fully metabolism, should not use the positive rate of Tg TgAb on Tg determination interference. Due to the current Tg, TgAb analysis sensitivity is limited, in 250 patients, only 83 cases of exact data for correlation analysis. So with the TgAb, Tg analysis sensitivity improvement, this study obtained view may change.
Jane's words, this study found that TgAb positive DTC patients, the positive rate of Tg was significantly lower than that in TgAb negative patients with DTC; serum Tg and TgAb concentration relationship. This is because of the positive and negative, TgAb TgAb in patients with DTC, the polyclonal TgAb fractions with different.
