I. Promotion of thyroid hormone (TSH)
TSH is a very sensitive specific indicator of testing the thyroid function. The tiny changes in free thyroid hormone concentration will cause significant changes in the TSH concentration.
TSH is an important indicator of monitoring monitoring of thyroxinxin inhibitory treatment after thyroid cancer. It is also one of the important monitoring indicators of hypothyroidism.
[TSH increases clinical significance]
Primary hypothyroidism, pituitary TSH tumor, subacute thyroid gland Inflammation recovery period, sub -clinical thyroid dysfunction, chronic lymphocytic thyroiditis, etc.
【TSH reduces clinical significance】
hyperthyroidism, sub -clinical hyperthyroid ) Oracle, drugs (glucocorticoids), Ku Xin syndrome, limb hypertrophy, etc.family The main hormone of the organs.
TT3 is an important indicator of detecting early hyperthyroidism and monitoring recurrence of hyperthyroidism.TT3 determination can also be used for detection of T3 hyperthyroidism and the diagnosis of pseudo -thyroid disease.
【TT3 height clinical significance】
hyperthyroidism, T3 hyperthyroidism, high TBG blood disease, medical source source source source Sexual hyperthyroidism, hyperthyroidism and early hypothyroidism and early hypothyroidism TT3 are relatively high, and sub -acute thyroiditis.
[TT3 reduction]
hypothyroid Heart, kidney, liver, lung failure, chronic consumer diseases, etc.), low TBG hematicmark, etc.
Three, Teta iodine -like gonadine (TT4)
TT4 is the most secrete hormone secretion. The metabolic regulation of TT4 is also controlled by the mound brain-pituitary prefix-thyroid gland axis.The biological activity of TT4 is lower than TT3.
[TT4 height clinical significance]
hyperthyroidism, T4 hyperthyroidism, high TBG hemophilia (pregnancy, pregnancy, pregnancy, pregnancy, pregnancy, Oral estrogen and oral contraceptives, family), sub -acute thyroiditis, thyroid hormone non -sensitive syndrome, drugs (amine iodine, contrast agent, etc.), altitude reaction.
[TT4 reduces clinical significance]
hypothyroidism, local thyroid monopoly, low TBG hemidmore ( Nephrine syndrome, chronic liver disease, protein loss of bowel disease, hereditary low TBG seria, etc.), chronic lymphocytic thyroiditis early stage, critical patients.
Fourth, free thyroxine (FT4)
free thyroid hormone is a true reflection of thyroid metabolism, Including FT3, FT4.
FT3 and FT4 determination is not affected by the concentration of protein concentration and characteristics of the characteristics of the characteristics of the FT4, so there is no need to determine the combination parameters. The indicator.
TSH, FT3 and FT4 three joint inspections, which are often used to confirm hyperthyroidism or nail low, and tracking efficacy.
【FT4 height clinical significance】
hyperthyroidism, T4 hyperthyroidism, hyperthyroidism, thyroid hormone does not not Sensitive syndrome, painless thyroiditis, low T3 syndrome, drugs (iodone), non -thyroid disease (acute fever, critical patients, etc.).
[FT4 reduces clinical significance]
hypothyroidism, sub -clinical hypotemoli, hyperthyroidism, kidney disease during hyperthyroidism, kidney disease, kidney disease, kidney disease Syndrome, drugs (glucocorticoids, etc.).
Five, free iodine metainetine (FT3)
[FT3 increases increase Clinical significance]
hyperthyroidism, sub-clinical hyperthyroidism, T3 hyperthyroidism, thyroid hormone unspented syndrome, , etc.
【FT3 reduces clinical significance】
hypothyroidism, low T3 syndrome, hyperthyroidism, drugs, drugs, drugs, drugs (Glucocorticoids, dopamine, etc.).
