正常TSH值的範圍在0.5~5.0 mU/L;free T4在0.8~1.8 ng/dL之間,一般篩檢應先測量TSH 值,若是過高則再次測量TSH及free T4來判斷,反之則不檢查。若TSH過高(通常>10 mU/L3)且free T4過低,則認定是甲狀腺低下,應開始給予補充治療。劑量與療效監測則依所測量到的血清T4濃度進行調整。 藥物治療 主要治療藥品為口服...
由於TSH的敏感度遠高於T3、T4,因此一般體檢主要是以TSH來做篩檢。如果TSH偏低或偏高,而T3、T4正常,就稱為隱藏性甲狀腺機能亢進(低下)。此時患者並不會有上述甲狀腺 ...。

Objective: To evaluate the association of TSH, free T3 (FT3), free T4 (FT4), and conversion (FT3:FT4) ratio values with incident hypertension. Materials and methods: The study included data from participants of the ELSA-Brasil study without baseline hypertension. Serum TSH, FT4 and FT3 level...
Serum levels of free T3 are associated with ApoA1 and ApoA2, whereas free T4 levels are associated with ApoB and LDL-cholesterol in euthyroid cardiovascula... There are a few papers reporting the association between thyroid hormones, cholesterol and lipoprotein in euthyroid cardiovascular patients....
Aim: Thyrotropin (TSH), thyroxine (T4) and triiodothyronine (T3) levels in serum are important for diagnosis of thyroid dysfunction. Thyroid function tests have considerable biological variations. Evaluation of the components of biological variation is essential to assess the usefulness of reference valu...
A 40-yr-old man who had acromegaly and hyperthyroidism due to a GH/TSH-secreting pituitary adenoma is described. Serum free T4 was 2.8 ng/dl, free T3 was 1.1 ng/dl, and TSH was 1.2-1.5 microU/ml; the latter was measured in an immunoradio... BECK-PECCOZ PAOLO,P Piscitelli,AMR SAN...
TSH with Reflex to Free T4 - This test may be useful in assessing thyroid dysfunction when pituitary disease is not suspected. In patients with clinical suspicion of hyperthyroidism or hypothyroidism, testing thyroid stimulating hormone (TSH) is the init
After three months, there was a fall in TSH to 12.74 μIU/ml, however, with unexpectedly high free T4 (FT4) - 6.8 ng/ml and free T3 (FT3) - 6.7 pg/ml concentrations [reference range (rr): 0.8-1.9 ng/ml and 1.5-4.1 pg/ml (SiemensW), respectively]. At this stage L-T4 was ...
