TSH levels are thus often used by doctors as a screening test, where the first approach is to determine whether TSH is elevated, suppressed, or normal. [25] Elevated TSH levels can signify inadequate thyroid hormone production (hypothyroidism) Suppressed TSH levels can point to excessive thyroid hormone production (hyperthyroidism) Because a ...
Hashimoto's thyroiditis is thought to be due to a combination of genetic and environmental factors. [5] [8] Risk factors include a family history of the condition and having another autoimmune disease. [3] Diagnosis is confirmed with blood tests for TSH, Thyroxine (T 4), antithyroid autoantibodies, and ultrasound. [3]
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.
Women, people with another autoimmune condition (like type 1 diabetes), and people between the ages of 30 to 60 are all at a greater risk of developing Graves’ disease, per Mayo Clinic.

Stress suppresses TSH, [5] and alterations in thyroid hormone levels may arise in psychiatric illness. In major depressive disorder, an NTIS-like phenotype may be observed, with reduced T3 and increased rT3. T4 may be elevated, and TSH is usually normal, although TSH's normal circadian rhythm may be disrupted. [2]
Subclinical hypothyroidism, a milder form of hypothyroidism characterized by normal thyroxine levels and an elevated TSH level, is thought to occur in 4.3–8.5% of people in the United States. [8] Subclinical hypothyroidism has been associated with an increased risk of atrial fibrillation (AF) and is the most frequent thyroid abnormality in ...
