* Thyroid lab values are in the optimal range (see the thyroid scale below) with TSH = 1.5 (optimal), FT4 = 1.26 (optimal), FT3 = 322 (optimal). Example 2: * George had a thyroidectomy to remove a cancerous tumor. He was healthy otherwise.

A free T4 test may be used along with or following a TSH test and sometimes with a free T3 test to: 1  Help detect too much or too little thyroid hormone (hyperthyroidism and hypothyroidism) and diagnose the cause. 2  Distinguish between different thyroid disorders. 3  Help diagnose pituitary disorders.

For example, if the normal height for a man is between 5’3” and 6’ and normal weight is between 130 lbs and 200 lbs., scanning the results column of a lab or other report (for flagged abnormal values) would declare a man who is 5’3” tall weighing 200 lbs to be just as normal as a man 6’ tall weighing 135 lbs.

TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism. Triiodothyronine (T3) and thyroxine (T4) are needed for normal growth of the brain, especially during the first 3 years of life. A baby whose thyroid gland does not make enough thyroid hormone (congenital hypothyroidism) may, in severe cases, be mentally retarded.

If you go by TSH normal ranges your score is normal, however TSH alone does not give a full picture of thyroid health. Insist on testing for Free T4, Free T3, Reverse T3, thyroid antibodies, ferritin and D3 as the first step. One test is just not enough to get a full picture.

Thyroid-Stimulating Hormone (TSH). Guide. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.

If the T4 is in the low (but still ‘normal’) range and the T3 is to the right of it in the low but normal range, it means that the T4 is converting to T3 at a high rate (more T3, less RT3). This is typically found when the thyroid gland is unable to keep up T4 production to meet the body’s needs.

Speaking roughly, normal levels of thyroid-stimulating hormone (TSH) are in the range of 0.4 to 4.0 mIU/L. However, each laboratory and test manufacturer identifies its own normal TSH range. This is based on the test, the equipment being used, and the patients being tested. The American Association of Clinical Endocrinologists has proposed a range of 0.3 to 3.0 for normal TSH levels. Using these cutoff values would lead to more people being diagnosed with an underactive thyroid (hypothyroidism).

In the cases of Free T4 (FT4) and Free T3 (FT3), the optimal zone is roughly half way between the usual lab normal Low-High values. Note that the normal range for these hormones may change a bit from lab to lab. In the case of TSH, the optimal zone is skewed far toward the low end of the standard lab Low-High range.

TSH stimulates the production and release of T4 (primarily) and T3 from the thyroid gland. Most of the T4 and T3 circulates in the blood bound to protein, while a small percentage is free (not bound). Blood tests can measure total T4, free T4, total T3, or free T3. The total T4 test has been used for many years, but it can be affected by the amount of protein available in the blood to bind to the hormone. Free T4 is not affected by protein levels and is the active form of thyroxine. The free T4 test is thought by many to be a more accurate reflection of thyroid hormone function and, in most cases, its use has replaced that of the total T4 test.
