It is common for physicians to carry out the TSH test. The test itself is simply a pituitary test (measuring communications pathway) and doesn’t establish what is really affecting the thyroid. When the person has hypothyroidism and the communication pathways are okay, the body’s TSH levels normally rise.
However, TSH elevations don’t usually occur with everybody having hypothyroidism. For instance, patients with Hashimotos’ could be having antibodies even before the levels rise. In such situations, central hypothyroidism manifests itself, suppressing the TSH levels, in turn covering what is really happening in the thyroid. The usual eventuality is a misdiagnosis.
The release of TSH hormones will depend on what is happening with the thyroid. Therefore, the person might have an overactive thyroid when the cells begin to break or in some cases normal thyroid activity. These fluctuations may give inaccurate results on the day the person tests.
TSH range has been a continuous debate. Previously, physicians set the standard range by using results obtained from measuring the average from people’s blood. TSH ranges that were as high as 8 – 9 was seen to indicate a healthy individual. However, this concept failed to account for the probability of thyroid diseases occurring in the so called healthy donors. In addition, the inclusion of the elderly in the exercise further rendered the result skewed because the functionality of the thyroid deteriorates with age. All this made the ranges obtained quite misleading.
Currently, looking at such ranges, they are pretty high especially for the young people. Recommended numbers range from 0.5 – 2.5. Nonetheless, the person’s symptoms should always be checked first. Even though the tests are important, they are the prime indicators of an autoimmune attack. Physicians recommend that the person undergo thorough thyroid antibody tests.
Persons with the autoimmune condition normally have their immune system make self antibodies and so does the immune system of normal individuals. The antibody test is therefore important.
