TSH and Antibodies

The Thyroid Stimulating Hormone (TSH) test is a pituitary test done to determine what takes place in the thyroid gland by measuring the communication pathways. If the thyroid is underactive yet the communication pathways are normal, there’ll be an elevation in TSH.

Nevertheless, this is not always the situation because at times central hypothyroidism occurs resulting in TSH suppression and this covers what is going on in the thyroid hence inaccurate results. For instance, in patients with Hashimotos the antibodies may be present 10 to 15 years before the TSH is elevated.

Therefore doctors should not only rely on the TSH test since the TSH hormone is released depending on what’s going on. Initially, a person may have an overactive thyroid and when cells breakdown, the thyroid becomes underactive thus the results may be inaccurate depending on the day one is tested.

TSH Range

In the 1950s, doctors wanted to determine the normal TSH levels. This was done by measuring the average from people’s blood and setting normal ranges based on the outcome though they didn’t take into consideration that most donors who seemed healthy had thyroid disease. Individuals who had ranges of TSH as high as 8 or 9 were regarded as healthy based on obtained information.

However, it’s now known that healthy individuals without thyroid disease should have a TSH of between 1.0 and 2.0. For example, a young person in his or her twenties should be closer to a 1.0.

It is recommended that everybody should get thyroid antibody test to establish when the body begins making antibodies to the thyroid gland such as thyroid peroxidase.

In addition to, one should get a copy of their labs and get tested fully since the TSH test does not reflect directly what takes place in the thyroid.
