This is a single-marker test measuring thyroid-stimulating hormone (TSH). It can be ordered as part of a custom panel.
TSH (thyroid-stimulating hormone) is the hormonal signal sent from the pituitary gland to the thyroid to tell the thyroid how much hormone to synthesize and release.
TSH is part of a sensitive hormonal feedback loop and is the most common thyroid test ordered by physicians.
The Thyroid Stimulating Hormone (TSH) test is a blood test commonly performed to determine the TSH levels and whether the thyroid gland is working correctly.
The ideal TSH can vary widely based on a person’s age, gender, and stage of life.
The conventional reference range provided by most labs is around 0.45-4.12 mlU/L.
Yet there is growing consensus that a narrower TSH range of 0.5 to 2.5 mlU/L may be more optimal for most healthy adults.
A physician may request a TSH test to determine the hormone levels, which will provide information about whether an individual’s thyroid gland is functioning normally.
The TSH test is usually requested with other thyroid tests, like the free T3, the free T4, and the anti-TPO antibody.
The blood TSH test may be used to:
