What should be the normal standard value of T3\T4?

1. Total T3 and T4: \ x0d \ Normal reference value: T31.34 ~ 2.73 nmol/L \ x0d \ T4 78.4 ~157.4 nmol/L \ x0d \ Meaning: ①T3 and T4 reflect thyroid function. \x0d\② Auxiliary diagnosis of hyperthyroidism (including hyperthyroidism recurrence) and hypothyroidism; \x0d\③ Determine the classification of hyperthyroidism; X0d is an effective index for doctors to evaluate curative effect and adjust medication when treating hyperthyroidism. ⑤ Serum TBG concentration affects the determination of T3 and T4. Therefore, the analysis of the results should be combined with clinical practice. \ x0d \ x0d \ 2。 Free T3(FT3) and free T4(FT4) \x0d\ Normal reference values: FT3 3.67 ~10.43mmol/L \ x0d \ FT4 7.5 ~ 21.1pm. The determination results of FT3 and FT4 are not affected by the change of TBG concentration, which can better reflect thyroid function. \ x0d \ \ x0d \ 3。 Thyrotropin \x0d\ Normal reference value: 0.34~5.60 mIU/L \x0d\ Significance: ①TSH is an important index for thyroid function determination; \x0d\② It can help diagnose hyperthyroidism, hypothyroidism and thyroiditis; \x0d\③ is an effective index for doctors to evaluate curative effect and adjust medication; ④ Simultaneous determination of T3, T4 or f T3, FT4 can diagnose thyroid diseases more accurately and comprehensively. At present, scholars at home and abroad agree that the combined detection of TSH, FT3 and FT4 is obviously superior to the detection of TSH, T3 and T4. \ x0d \ \ x0d \ 4。 Thyrotropin receptor antibody (TRAb) \x0d\ Normal reference value:
