  Graves’ disease is the most common cause of hyperthyroidism. […] Failure to diagnose Graves’ disease in a timely manner can predispose thyroid storm which carries high morbidity and mortality. […] Early diagnosis and management of Graves’ disease can also prevent severe cardiac complications such as atrial flutter, atrial fibrillation, and high output cardiac failure. […] Diagnosis of Graves disease starts with a thorough history and physical examination. History should include a family history of Graves disease. […] The initial test for diagnosis of hyperthyroidism is the thyroid-stimulating hormone (TSH) test. If TSH is suppressed, one needs to order Free T4 (FT4) and Free T3 (FT3). […] Graves diagnosis can be obvious with a careful history and physical examination. […] Measurement of TSH receptor antibody (TRAb): There are two available assays, the thyroid stimulating immunoglobulin (TSI) and thyrotropin-binding inhibiting (TBI) immunoglobulin or thyrotropin-binding inhibitory immunoglobulin (TBII).

  Graves disease is the most common cause of hyperthyroidism in countries with sufficient iodine intake. […] Diagnosis is mostly clinical. The combination of elevated TSH receptor antibodies (or elevated radioactive iodine/technetium-99 uptake by the thyroid if TSH receptor antibody testing is unavailable or diagnosis is uncertain); suppressed TSH; and elevated levels of circulating thyroid hormones (free T4 and total or free T3) is the standard for diagnosis of Graves hyperthyroidism. […] Diagnosis is mostly clinical and is usually confirmed by laboratory evidence of thyroid dysfunction, most commonly hyperthyroidism and the presence of circulating TSH receptor antibodies. […] The first tests to order include thyroid-stimulating hormone (TSH), serum free or total T4, serum free or total T3, and TSH receptor antibodies (TRAb). […] Tests to consider include calculation of total T3/T4 or FT3/FT4 ratio, radioactive iodine or technetium-99 uptake, thyroid scan (scintigraphy), thyroid peroxidase antibodies (TPOAb), thyroid ultrasound, CT or MRI scan of orbit, and skin biopsy.

  https://www.aafp.org/pubs/afp/issues/2005/0815/p623.html

  The proper treatment of hyperthyroidism depends on recognition of the signs and symptoms of the disease and determination of the etiology. The most common cause of hyperthyroidism is Graves disease. […] The diagnostic workup begins with a thyroid-stimulating hormone level test. […] Graves disease is the most common cause of hyperthyroidism, accounting for 60 to 80 percent of all cases. […] An undetectable TSH level is diagnostic of hyperthyroidism. […] Antithyroid antibodies are elevated in Graves disease and lymphocytic thyroiditis but usually are not necessary to make the diagnosis. […] Thyroid-stimulating antibody levels can be used to monitor the effects of treatment with antithyroid drugs in patients with Graves disease. […] Radionuclide uptake and scan easily distinguishes the high uptake of Graves disease from the low uptake of thyroiditis and provides other useful anatomic information.

  https://www.ncbi.nlm.nih.gov/books/NBK285548/

  Diagnosis of the classic form of Graves disease is easy and depends on the recognition of the cardinal features of the disease and confirmation by tests such as TSH and FTI. […] The diagnosis of Graves disease is usually easily made. The combination of eye signs, goiter, and any of the characteristic symptoms and signs of hyperthyroidism forms a picture that can hardly escape recognition. […] The diagnosis of Graves Disease does not only depend on thyrotoxicosis. Ophthalmopathy, or pretibial myxedema may occasionally occur without goiter and thyrotoxicosis, or even with spontaneous hypothyroidism. […] The physician applying any of these forms of therapy to the control of thyrotoxicosis should also pay heed to the patients emotional needs, as well as to his or her requirements for rest, nutrition, and specific antithyroid medication.

• #5 Graves’ Disease: What It Is, Causes, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/15244-graves-disease

  Graves disease is an autoimmune disease that affects the thyroid gland. […] Graves disease is an autoimmune disease in which your immune system attacks healthy tissue in your thyroid gland for unknown reasons. Its the most common cause of hyperthyroidism, a condition in which your thyroid gland makes too much thyroid hormone. […] Your healthcare provider will ask about your symptoms and medical history, including your family history of thyroid disease, and perform a physical exam. They may also order the following tests to confirm a Graves disease diagnosis: […] Thyroid blood tests: These blood tests check the level of thyroid hormone in your blood and amounts of thyroid-stimulating hormone (TSH). A low TSH level indicates that your thyroid gland is producing too much hormone. The overproduction causes your pituitary gland to make less TSH.

  https://www.merckmanuals.com/professional/endocrine-and-metabolic-disorders/thyroid-disorders/hyperthyroidism

  Graves disease (toxic diffuse goiter), the most common cause of hyperthyroidism, is characterized by hyperthyroidism and one or more of the following: […] Graves disease is caused by an autoantibody (TSI) against the thyroid receptor for thyroid-stimulating hormone (TSH); unlike most autoantibodies, which are inhibitory, this autoantibody is stimulatory, thus causing continuous synthesis and secretion of excess T4 and T3. […] The cause can often be diagnosed clinically (eg, the presence of signs specific to Graves disease). […] TSH receptor antibodies can be measured to evaluate for Graves disease. […] Most patients with Graves disease have circulating antithyroid peroxidase antibodies, and fewer have antithyroglobulin antibodies. […] The most common etiology of hyperthyroidism is Graves disease, caused by autoimmune-stimulated excessive hormone synthesis by the thyroid gland.

• #7 Graves’ Disease

  https://www.thyroid.org/graves-disease/

  The diagnosis of hyperthyroidism is made on the basis of your symptoms and findings during a physical exam and it is confirmed by laboratory tests that measure the amount of thyroid hormones (thyroxine, or T4, and triiodothyronine, or T3) and thyroid-stimulating hormone (TSH) in your blood. […] Clues that your hyperthyroidism is caused by Graves disease are the presence of Graves eye disease and/or dermopathy, a symmetrically enlarged thyroid gland and a history of other family members with thyroid or other autoimmune problems, including type 1 diabetes, rheumatoid arthritis, pernicious anemia or painless white patches on the skin known as vitiligo.

  The 3rd generation TBII assays have a sensitivity of 97.4% and specificity of 99.2% for GD diagnosis. Thus, depending on the availability, we recommend that TRAbs can be used as sensitive and specific tools for differential diagnosis of thyrotoxicosis, and also for the rapid and accurate diagnosis of GD in all patients with clinical and biochemical thyrotoxicosis. […] R3. Baseline levels of TRAbs, along with other clinical indicators, can help in predicting treatment response to therapy in Graves Disease. […] R4. Baseline levels of TRAbs can help in predicting prognosis and recurrence of Graves Disease, especially in young individuals. […] After 24 months of therapy with methimazole (MMI), 63.3% of patients with baseline TRAbs values of 10 IU/L were observed to attain remission, and the mean time of entering remission was 16.4 months; the corresponding values for patients with baseline TRAbs 10 IU/L were 39.4% and 21.5 months respectively. Higher baseline TRAbs levels were associated with greater risk of GD relapse, independent of age, sex, race, smoking status, and TPOAb levels; the association was more apparent among younger patients but was not significant in patients aged 57 years.

  https://blogs.the-hospitalist.org/content/how-graves-disease-diagnosed-and-evaluated

  Graves disease diagnosis mainly is clinical, but also is supported by elevated free levels of thyroid hormones (mainly triiodothyronine [T3]) and suppressed TSH levels. Anti-thyrotropin receptor antibodies generally are present. Imaging in Graves disease is characterized by increased radioiodine uptake, as well as increased perfusion by Doppler ultrasonography. […] The classic presentation of Graves disease is a suppressed TSH and elevated serum T3 and T4 levels. Generally, T3 is higher than T4, which also occurs in toxic multinodular goiter, solitary hyperfunctioning nodule, and iodine-induced hyperthyroidism. Most patients with Graves disease also have anti-thyroid antibodies, although these are not required for the diagnosis. […] A thyroid radioiodine-uptake study provides a measure of iodine uptake, as well as an image of functioning thyroid tissue; the imaging is done 24 hours after the intake of iodine-123 or iodine-131. Generalized increased uptake is characteristic of Graves disease.

  Graves disease is an autoimmune condition caused by immune cells attacking the thyroid gland, which responds by secreting an excess amount of thyroid hormone. […] Approximately one-third of patients with Graves disease have some signs and/or symptoms of TED, while only 5% have moderate-to-severe TED. […] In patients with Graves disease who undergo treatment with radioactive iodine therapy, it is important to closely monitor thyroid levels afterwards as untreated hypothyroidism (low thyroid hormone levels) can worsen TED. […] The diagnosis of TED is usually made clinically. To determine the severity of TED, your physician may perform the following tests to assess your vision and the changes in the tissues around your eyes: vision testing, visual fields testing, eyelid measurements, checking the optic nerves, and sometimes photographs. Laboratory finding are performed to evaluate for hyperthyroidism. CT or MRI scans can be performed in individuals who have moderate to severe eye disease to assess the risk of further complications.
