甲亢病人应做哪些实验室检查

    One, the determination of serum thyroid hormone in 1 serum free thyroxine ( FT4 ) and three free triiodothyronine ( FT3 ). FT3, FT4 is circulating thyroid hormone activity, from the blood of TBG changes, directly reflect the functional state of the thyroid gland. Its sensitivity and specificity were significantly more than the total T3 ( TT3 ), T4 ( TT4 ). Normal values of each laboratory has difference. 2 serum total thyroxine ( TT4 ). Determination of thyroid function is the most basic screening index. More than 99.95% of the T4 and serum protein binding, mainly TBG, TBG affected by pregnancy, estrogen, viral hepatitis and other factors and elevated, androgen, hypoalbuminemia ( severe liver disease, nephrotic syndrome ),得甲亢會出現哪些癥狀
prednisone, affect and drop. Three 3 of total serum triiodothyronine ( TT3 ). 99.5% combined with serum protein, also by TBG, the variation of its concentration is often associated with TT4 changed in parallel, but in early recurrence of hyperthyroidism, early rising quickly, measuring TT3 for the diagnosis of this disease is a sensitive index; the disease early, in the treatment of recurrence after curative effect observation and treatment of aura, as sensitive, especially for the diagnosis of type T3 hyperthyroidism specific index. 4 - T3. Diagnosis of low T3 syndrome is important index. In two,

            TSH immunoradiometric determination analysis ( IRMA method). Can measure the normal lower limit, has the very high sensitivity, so it is also called STSH ( SensitiveTSH ). Widely used in hyperthyroidism and hypothyroidism diagnosis and treatment monitoring. Three, thyrotropin releasing hormone ( TRH ). Exciting test such as the intravenous injection of TRH200μg TSH increased, can be excluded from this disease is not increased; such as TSH ( no response ) supported the diagnosis of primary hyperthyroidism. Care should be taken not to increase also visible in normal thyroid function in Grave''s ophthalmopathy, pituitary disease with TSH secretion deficiency. This experiment with fewer side effects, on coronary heart disease or hyperthyroid heart disease than T?? 3 inhibition test for safety. Four, 131 rate of iodine uptake of thyroid. Diagnostic accordance rate was 90%, iodine deficiency goiter can also be raised, but generally no peak fronting, can be used for T3 inhibition test in the differential. This method can not reflect the severity and treatment of disease changes, 得了甲状腺结节哪里治好？
but can be used for the identification of different etiologies, such as hyperthyroidism, subacute thyroiditis. ?? Five, three triiodothyronine inhibition test (T3 inhibition test ). For differentiating hyperthyroid and simple goiter. Six, thyroid stimulating antibody ( TSAb ) determination. The positive rate of up to 80%～ 90%, contribute to the etiological diagnosis.
