TSH- (Thyrotropin):
TSH is synthesized by the Pituitary gland to stimulate the thyroid for controlling the energy used by the body. This test is used for screening the TSH level of the blood for detecting thyroid disorders like hypothyroidism and hyperthyroidism. This test used to detect congenital hypothyroidism in newborns.
CLINICAL INFORMATION :
The values reflect if the thyroid gland is abnormal if it is overactive (hyperthyroidism) or under-active (hypothyroidism). Hence with the presenting signs and symptoms, the thyroid disorder can be screened and detected by diagnostic methods like hormone assays.
High levels of TSH mean thyroid hormones are not secreted in optimal levels hence low thyroid hormones trigger positive feedback to secrete more TSH hormones. While on the other hand low TSH levels values in the blood mean thyroid hormone is secreted in excess hence negative feedback mechanism prevents TSH release.
This test is usually done for altered levels of thyroid hormone secretions. This test is suggested in patients with symptoms for hyperthyroidism present with signs and symptoms of increased appetite, nervousness, restlessness, inability to concentrate, weakness, irregular heartbeat, sleeping difficulties, fine and brittle hair and on the contrary patients with hypothyroidism present their signs and symptoms of feeling tired, weight gain, feeling cold, weakness and aches in muscle and joints, hair loss, itchy and dry skin, depression, trouble concentrating or remembering, constipation and heavy or irregular periods in females. Other associated tests include radioimmunoassay, ELISA, spectrometric method, etc.
