  2. Hyperthyroxinemia - Wikipedia

    en.wikipedia.org/wiki/Hyperthyroxinemia

    Thyroxine or tetraiodothyronine (T4) is produced by the thyroid gland. The term is sometimes used to refer to hyperthyroidism, but hyperthyroidism is a more general term. [2] When the level of thyroxine (T4) in the blood exceeds normal range, it can lead to symptoms such as irritability and unexplained weight loss. [3] Types include:

  3. Hyperthyroidism - Wikipedia

    en.wikipedia.org/wiki/Hyperthyroidism

    People with hyperthyroid will typically "take up" higher than normal levels of radioiodine. Normal ranges for RAI uptake are from 10 to 30%. In addition to testing the TSH levels, many doctors test for T 3, Free T 3, T 4, and/or Free T 4 for more detailed results. Free T 4 is unbound to any protein in the blood.

  4. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    Free T4 levels should be measured in the evaluation of hypothyroidism, and low free T4 establishes the diagnosis. T3 levels are generally not measured in the evaluation of hypothyroidism. [13] Free T4 and total T3 can be measured when hyperthyroidism is of high suspicion as it will improve the accuracy of the diagnosis. Free T4, total T3 or ...

  5. Thyroid function tests - Wikipedia

    en.wikipedia.org/wiki/Thyroid_function_tests

    Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy.

  6. Thyroid hormone binding ratio - Wikipedia

    en.wikipedia.org/wiki/Thyroid_hormone_binding_ratio

    Thyroid hormone binding ratio (THBR) is a thyroid function test that measures the "uptake" of T3 or T4 tracer by thyroid-binding globulin (TBG) in a given serum sample. This provides an indirect and reciprocal estimate of the available binding sites on TBG within the sample.

  7. Thyroid-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Thyroid-stimulating_hormone

    The therapeutic target range TSH level for patients on treatment ranges between 0.3 and 3.0 μIU/mL. [18] For hypothyroid patients on thyroxine, measurement of TSH alone is generally considered sufficient. An increase in TSH above the normal range indicates under-replacement or poor compliance with therapy.

  8. Thyrotoxic myopathy - Wikipedia

    en.wikipedia.org/wiki/Thyrotoxic_myopathy

    To understand how high levels of thyroxine can be toxic and lead to thyrotoxic myopathy physiologically, consider basic neuromuscular junction function. Under normal circumstances, muscle contraction occurs when electrical impulses travel down descending axons from the brain or spinal cord towards the neuromuscular junction.

  9. Thyrotoxic periodic paralysis - Wikipedia

    en.wikipedia.org/wiki/Thyrotoxic_periodic_paralysis

    The abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant. Treatment of the low levels of potassium in the blood, followed by correction of the hyperthyroidism, leads to complete resolution of the attacks.
