What does TSH 3rd generation test for?

Third-generation thyroid-stimulating hormone (TSH) assays are generally the most sensitive screening tool for primary hypothyroidism. If TSH levels are above the reference range, the next step is to measure free thyroxine (T4) or the free thyroxine index (FTI), which serves as a surrogate of the free hormone level.

What should my TSH 3rd generation be?

According to the ATA, >95% of the normal population will have a TSH level below 2.5 mIU/L with an average TSH level of approximately 1.5 mIU/L. 4 Spectra has validated a TSH reference range of 0.300-3.000 mIU/L, which is also the range recommended by the American Association of Clinical Endocrinologists (AACE).

What does high TSH 3rd generation mean?

If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism. That’s because it indicates your pituitary gland is producing more TSH in an effort to stimulate your thyroid to produce thyroid hormone, according to the Mayo Clinic.

What is normal TSH level for female?

TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.

What does the TSH 3rd generation test mean?

The thyroid stimulating hormone (TSH) 3rd generation test is a blood test that measures the amount of thyroid stimulating hormone in the bloodstream. It is used to check for hypothyroidism and hyperthyroidism.

How does the TSH ultrasensitive blood test work?

The TSH Ultrasensitive test is one of the most significant and consistent tests to appraise functioning of thyroid in an individual. Simply, a blood test is conducted for Primary Hyperthyroidism, Hypothyroidism, estimating TRH or to monitor patients going through thyroid replacement therapy.

What can a TSH test tell you about your health?

A TSH test measures the amount of the hormone in the blood. Doctors can use the results to diagnose thyroid conditions, such as hypothyroidism and hyperthyroidism.

Is the TSH test the gold standard for thyroid disease?

The TSH test is the “gold standard” in diagnosing and monitoring thyroid disease, but as with any medical test, there are exceptions and variations to what the test may mean, as well as situations in which the test may be inaccurate. If your TSH levels don’t seem to reflect how you are feeling, speak up.
