Thyroid Function Free Sample Thyroid Stimulating Hormone (TSH) Test Kit (Fluorescence Immunoassay) Application It is suitable for quantitative determination of thyroid stimulating hormone (TSH) in human plasma or whole blood in vitro. Package 1 test/kit, 5 tests/kit, 25 tests/kit, 50 tests/kit. Clinical Significance TSH is one of the hormones secreted by the anterior pituitary, and its main function is to control and regulate the activity of the thyroid gland. Determination of thyroid-stimulating hormone in serum (plasma) is one of the important indicators for the diagnosis and treatment of hyperthyroidism and hypothyroidism, as well as for the study of the hypothalamus-pituitary-thyroid axis. It is an indispensable tool in the diagnosis of hypothyroidism and in the differential diagnosis of primary and secondary (hypothalamic or pituitary) hypothyroidism. In the treatment of hyperthyroidism and hypothyroidism, its TSH can be used as an indicator of curative effect. In addition, it can be used to observe the reserve function of pituitary TSH, and can further distinguish the lesions of the hypothalamus and pituitary. The TSH test is a primary screening test to find out thyroid function. Small changes in free thyroid concentrations can lead to significant adjustments in TSH concentrations in the opposite direction. 1. Elevated serum TSH: common in primary hypothyroidism, TSH-secreting tumor, iodine-deficiency endemic goiter, thyroid hormone resistance syndrome, etc. 2. Decreased serum TSH: common in primary hyperthyroidism, TSH gene mutation, various pituitary diseases (such as pituitary adenoma, pituitary inflammation, pituitary hemorrhagic disease or injury disease, etc.) affect the function of TSH cells. thyroiditis, and the clinical application of high-dose glucocorticoids, etc. Components The kit consists of thyroid stimulating hormone detection reagent card, detection buffer, ID card, and instructions. Thyrotropin Thyrotropin is a hormone secreted by the anterior pituitary gland. Its main function is to promote the synthesis and secretion of thyroid hormone by thyroid tissue. The thyroid stimulating hormone secreted by the anterior pituitary reaches the thyroid tissue through the pituitary and thyroid axis to promote thyroid hyperplasia and promote the synthesis of thyroid hormone required by the body, so as to meet the normal metabolic needs of the body. Thyroid diseases, including pituitary lesions, will affect the secretion of thyroid stimulating hormone; In hyperthyroidism, thyroid hormone is secreted too much. Through negative feedback to the pituitary, thyroid stimulating hormone is inhibited, and its secretion will be reduced銆?/p Thyrotropin is promoted by thyrotropin releasing hormone secreted by hypothalamus, on the other hand, it will be inhibited by thyroid hormone feedback mechanism. The main function of thyroid stimulating hormone is to control and regulate the proliferation of thyroid cells, regulate the synthesis and secretion of thyroid hormone, and control the inflow of thyroid hormone into the blood. The hormone content in serum is an index to diagnose human hyperthyroidism or hypothyroidism. Thyroid stimulating hormone (TSH): 1. Normal range: 2 ~ 10mu / L. 2. Examination introduction: thyroid stimulating hormone can promote the proliferation of thyroid follicular epithelial cells and the synthesis and release of thyroid hormone. 3. Clinical significance: increased: primary hypothyroidism, Hashimoto disease with hypothyroidism, exogenous thyrotropin secreting tumors (lung and breast), recovery stage of subacute thyroiditis. Ingestion of metal lithium, potassium iodide and thyroid stimulating hormone releasing hormone can increase thyroid stimulating hormone. 4. Reduction: pituitary hypothyroidism, hyperthyroidism caused by non thyroid stimulating hormone tumor, intake of aspirin, corticosteroids and intravenous heparin. 5. Special note: Hashimoto's disease, also known as Hashimoto's thyroiditis and chronic lymphocytic thyroiditis, is an autoimmune disease (that is, your immune system attacks your normal tissues and organs, causing the decline of normal function). It is more common in middle-aged women, often manifested as diffuse goiter and hypothyroidism in the late stage.Thyroid Function Free Sample website:http://www.modaivds.com/all-poct-products/thyroid-function/
