18 Φεβ 2024 · Characteristic laboratory findings of hypothyroidism include elevated TSH levels and low free T4 levels. Today, the diagnosis of hypothyroidism is easily made by the use of simple blood tests and can be treated with exogenous thyroid hormone.
Low thyroid hormone levels cause the body’s functions to slow down, leading to general symptoms like dry skin, fatigue, loss of energy, and memory problems. Hypothyroidism is diagnosed by a simple blood test for thyroid-stimulating hormone (TSH).
The finding of an elevated TSH and low FT4 or FTI indicates primary hypothyroidism due to disease in the thyroid gland. A low TSH and low FT4 or FTI indicates hypothyroidism due to a problem involving the pituitary gland. A low TSH with an elevated FT4 or FTI is found in individuals who have hyperthyroidism.
15 Μαΐ 2021 · Low-end normal TSH is 0.4 mIU per L. 2, 5 – 7 The upper-end normal range is from 4.0 to 4.5 mIU per L. 2, 5 – 7 FT 4 level is used to distinguish clinical (low FT 4) from subclinical...
• Hypothyroidism: normalization of TSH within age-specific reference range • Thyroid cancer: undetectable to 0.5 -2 mIU/L, depending on disease status and clinical risk
Treatment with levothyroxine, with TSH based dose adjustments, has been shown to frequently result in levels of FT4 and Free T3 (FT3) that are insufficient to achieve symptom relief and metabolic normality (5, 9). Symptomatic change correlates best with serum thyroid hormone levels, not TSH (6, 10).
