However, these parameters are difficult to use in clinical practice. In this study, the prevalence of T3-toxicosis was not as high as expected in newly diagnosed untreated patients with thyrotoxicosis. Either T3 or T4 can provide diagnostic value for the diagnosis of thyrotoxicosis. T3 is an active form of thyroid hormone that is deiodinated from T4 by type 1 iodothyronine deiodinase D1 as well as type 2 D2.
In humans, the thyroid expresses both D1 and D2 [16]. High expression of D2 in Graves' thyroid tissue and in some thyroid adenomas has been reported to contribute to relatively high serum T3 levels [17]. Also, the frequency of T3-toxicosis was higher in those with iodine deficiency. This study had a lower prevalence of T3-toxicosis than a previous study [9] , which might be due to differences in the selected study population.
We collected subjects only for newly diagnosed thyrotoxicosis, and included patients from every clinic in the hospital. In contrast, the previous study included only patients from the endocrine clinic, who usually represent only severe cases with high T3 levels [9].
In an era of economic crises, cost-effectiveness is one of the most important health management concerns. In summary, a higher ratio of FT3 to FT4 suggests that the patient may have Graves' disease, and a very low ratio supports a diagnosis of subacute thyroiditis.

Abstract Background The measurement of free thyroid hormone, instead of the total form, is more commonly used in current practice. Keywords: Thyroid function tests, Thyrotoxicosis, Graves' disease, Subacute thyroiditis, Sensitivity and specificity.
Introduction Thyrotoxicosis is a common thyroid dysfunction. Materials and methods 2. Results 3. Demographic data A total of patients with newly-diagnosed of thyrotoxicosis were recruited for the final analysis. Open in a separate window. Sensitivity and specificity of thyroid hormones for diagnosis of thyrotoxicosis The areas under the ROC curves of FT3 and FT4 for the diagnosis of Graves' disease were 0. Discussion The ratio of total T3 to total T4 is commonly used for differentiating the etiology of thyrotoxicosis between Graves' disease and subacute thyroiditis.

Thyroiditis FAQs. The course of thyroiditis depends on the type of thyroiditis. Silent thyroiditis, Painless thyroiditis Anti-thyroid antibodies, autoimmune disease Thyrotoxicosis followed by hypothyroidism.
Post partum thyroiditis Anti-thyroid antibodies, autoimmune disease Thyrotoxicosis followed by hypothyroidism. Thyroid function tests, thyroid antibody tests Often continues as long as the drug is taken Radiation induced Follows treatment with radioactive iodine for hyperthyroidism or external beam radiation therapy for certain cancers.
Occasionally thyrotoxicosis, more frequently hypothyroidism.. Thyroid function tests Thyrotoxicosis is transient, hypothyroidism is usually permanent Acute thyroiditis, Suppurative thyroiditis Bacteria mainly, but any infectious organism Occasionally painful thyroid, generalized illness, occasional mild hypothyroidism Thyroid function tests, radioactive iodine uptake, fine needle aspiration biopsy Resolves after treatment of infectious cause, may cause severe illness. Treatment depends on the type of thyroiditis and the clinical presentation.
Thyrotoxicosis — Beta blockers to decrease palpitations fast heart rate and decrease tremors may be helpful. As symptoms improve, the medication is tapered off since the thyrotoxic phase is temporary. Antithyroid medications see Hyperthyroid brochure are not used for the thyrotoxic phase of thyroiditis of any kind since the thyroid is not overactive.
In patients who are symptomatic with the hypothyroid phase of subacute, painless and postpartum thyroiditis, thyroid hormone therapy is also indicated. If the hypothyroidism in these latter disorders is mild and the patient has few, if any, symptoms, then no therapy may be necessary.
If thyroid hormone therapy is begun in patients with subacute, painless and post-partum thyroiditis, the treatment should be continued for approximately months and then tapered to see if it is required permanently. Thyroidal pain — The pain associated with subacute thyroiditis usually can be managed with mild antiinflammatory medications such as aspirin or ibuprofen.
Occasionally, the pain can be severe and require steroid therapy with prednisone. A primary care physician may make the diagnosis of hyperthyroidism, but help may be needed from an endocrinologist, a physician who is a specialist in thyroid and other endocrine diseases.
The best test to determine overall thyroid function is the thyroid stimulating hormone TSH level. TSH is produced in the brain and travels to the thyroid gland to stimulate the thyroid to produce and release more thyroid hormone. A high TSH level indicates that the body does not have enough thyroid hormone. A TSH level lower than normal indicates there is usually more than enough thyroid hormone in the body and may indicate hyperthyroidism. When hyperthyroidism develops, free thyroxine T4 and free triiodothyronine T3 levels rise above normal.
Other laboratory studies may help identify the cause of hyperthyroidism. Thyroid-stimulating immunoglobulins TSI can be identified in the blood when Graves' disease is the cause of hyperthyroidism. Thyroid peroxidase antibodies and other anti-thyroid antibodies are also seen in some disorders leading to hyperthyroidism. Currently, there are several effective treatments available for hyperthyroidism depending on the cause, severity, and several other factors.
The most common treatments for hyperthyroidism include antithyroid medications, radioactive iodine, and thyroid surgery. Antithyroid medication most often methimazole decreases thyroid hormone production. Antithyroid medicine does not cure the disease but works while the patient takes the medication.
