People who suspect to have thyroid problems undergo thyroid tests to be able to determine if they are suffering from a thyroid disorder and which thyroid disorder they have. A physician uses the tests as basis for diagnosis. Thyroid tests also known as thyroid function tests are tests done to check an individual’s thyroid function in the body. It also checks the level of thyroid stimulating hormones or TSH in the body. High levels of TSH indicate that they thyroid gland is failing in producing thyroid hormones due to hypothyroidism. The thyroid gland functions normally if the test shows a normal level of TSH.

Thyroid Blood Test

One of the tests that physicians conduct to gauge an individual’s thyroid stimulating hormones in the body is the thyroid blood test. Thyroid blood test shows undetected imbalances that go with other limited assessments. It only does not help diagnose hypothyroidism and hyperthyroidism but also points sub-clinical manifestations found in other thyroid dysfunctions. Thyroid blood tests assess the following:

  • Free thyroxine (T4)

  • Anti-thyroglobulin antibodies (anti-TG)

  • Free triiodothyronine (T3)

  • Hypersensitive stimulating hormones (TSH)

After the blood is sent to the laboratory for analysis, a diagnosis is then given to an individual to know more about which thyroid disorder one is suffering from.

Thyroid Test Ranges

The reference range determines the validity of a thyroid stimulating hormone test. After submitting one’s self for a thyroid test, results will be assessed and checked if it within the normal thyroid hormone range. It serves as a clear indication that a person is suffering from a thyroid disorder if thyroid hormone levels are higher or lower than the normal hormone range. Numerous problems arise when one’s thyroid gland is dysfunctional which leads to having individuals experience symptoms of hyperthyroidism, hypothyroidism and even cancer. The earlier the thyroid problem is diagnosed the better chances of having it treated.

Thyroid Test t4

Thyroid tests help physicians evaluate a person’s thyroid function. There are two types of thyroid tests that a person may undergo. These are the total t4 test and the free t4 test. Physicians use total t4 test to be able to provide a diagnosis whether a person is suffering from hypothyroidism or hyperthyroidism. However, at times, diagnosis becomes difficult since protein levels in the body affect the result of this test. This is where the free t4 test comes in. This test provides accurate results and diagnosis since it is not affected by a person’s protein level in the body.

Thyroid Test Results

Thyroid test results are the ones used by physicians to be able to provide diagnosis. Prior to getting the thyroid test results, blood samples are first sent to the laboratory for examination. Basing on the thyroid test result, a physician can then inform the individual on which thyroid disorder he/she may be suffering from. Physicians will then discuss appropriate treatment options.
