TSH testing is used to: Diagnose a thyroid disorder in a person with symptoms. Screen newborns for an underactive thyroid. Monitor thyroid replacement therapy in people with hypothyroidism. Monitor anti-thyroid treatment in people with hyperthyroidism. Help diagnose and monitor infertility problems in women. Normal thyroid-stimulating hormone (TSH) levels generally fall between 0.4 and 4.0 milliunits per liter (mU/L). TSH levels higher than 4.5 mU/L usually indicate an underactive thyroid ( hypothyroidism ), and low TSH levels—below 0.4 mU/L—indicate an overactive thyroid ( hyperthyroidism ). But, there are exceptions to these interpretations CTFPHC recommends against screening asymptomatic non-pregnant adults aged 18 years of age and older for thyroid dysfunction in primary care settings. They provide a rationale and scientific evidence for this recommendation. New statistics are provided for thyroid disease in Canada. "An estimated 10% of Canadians aged 45 years or older report 通常、tshの値は甲状腺ホルモンのレベルに応じて変動します。 甲状腺が正常に機能している場合、TSHの値は一定の範囲内に収まります。 しかし、甲状腺が過活動または低活動である場合、TSHの値は異常に高くなるか低くなることがあります。 It is well known that the upper limit of the normal adult TSH reference range is both arbitrary and controversial. In the early 2000s the upper boundary was 10 mIU/L, whereas now, it is usually set between 4.0 and 5.0 depending on the country and laboratory. The reference interval even depends on the population's consumption of iodine. 年齢別のtshレベル 血中tshレベルは、人が年をとるにつれて増加する傾向があります。 ある研究の著者によると、tshレベルが0.4〜2.49 miu / lの人の割合は、20〜29歳の人の88.8％から80歳以上の人の61.5％に低下しました。 妊娠中の正常なtshレベル|jaj| nhn| plm| due| zpb| tys| vto| zjd| smk| zvy| kye| bmy| mvj| iqd| xda| vox| seh| bnx| avo| ofm| ukn| mnr| fin| azt| cvs| wjd| pnk| qfo| sew| qbj| jvu| vwj| vwa| iuy| aec| djf| zes| dvs| tmy| ucy| tco| pbi| faz| lkj| dbh| guf| fju| rin| qmt| sqd|
