Trichomoniasis Testing

The thyroid-stimulating hormone (TSH) test is often the test of choice for evaluating thyroid function and/or symptoms of a thyroid disorder, including hyperthyroidism or hypothyroidism.
TSH is produced by the pituitary gland, a tiny organ located below the brain and behind the sinus cavities. It is part of the body's feedback system to maintain stable amounts of the thyroid hormones thyroxine (T4) and triiodothyronine (T3) in the blood and to help control the rate at which the body uses energy.
Clinical Significance
    For differential diagnosis of primary, secondary, and tertiary hypothyroidism. Also useful in screening for hyperthyroidism. This assay allows adjustment of exogenous thyroxine dosage in hypothyroid patients and in patients on suppressive thyroxine therapy for thyroid neoplasia.
Alternative Names
    Thyrotropin,Thyroid Stimulating Hormone
TSH testing is used to:
    Diagnose a thyroid disorder in a person with symptoms
    Screen newborns for an underactive thyroid
    Monitor thyroid replacement therapy in people with hypothyroidism
    Monitor anti-thyroid treatment in people with hyperthyroidism
    Help diagnose and monitor infertility problems in women
    Help evaluate the function of the pituitary gland (occasionally)
    Screen adults for thyroid disorders, although expert opinions vary on who can benefit from screening and at what age to begin
