Common Thyroid Test Types You Must Understand
Found in the neck’s front portion, thyroid is a butterfly-shaped gland. It is important that you get a thyroid test in case there is an issue with the thyroid function. Ignoring abnormal thyroid function could mean tampering with the greater endocrine system. There are a number of reasons why you need a thyroid test. It is important to perform tests so as to get a quality diagnosis of the ailment.
- Specialists use these tests to analyze the thyroid gland performance.
- The tests also help in the diagnosis of the factors causing thyroid disorders: hypothyroidism and hyperthyroidism.
- Thyroid tests are useful in getting the outright treatment options.
Thyroid gland tests
Four common types of tests are used to detect the efficiency of the thyroid gland. They are as highlighted below:
1. TSH test: This type of thyroid test is used to check the working status of the gland. It assesses the overall amount of TSH that is produced by the pituitary gland. The test gives accurate results on the levels of TSH in the blood. If TSH poorly responds to the pituitary gland, there are likely body abnormalities. This test helps in understanding the status so as to know the next examinations.
2. T3 test: This type of thyroid test is useful in case of hyperthyroidism signs. The test works best when the FT4 level is normal. Even during normal FT4 levels, hyperthyroidism could occur.
3. T4 test: This type of test is very useful. T4 is secreted in the blood in two different forms:
- T4 that is meant to match blood and body proteins.
- FT4 that is the active form of the gland. It is available to enter the tissues when required.
Hyperthyroidism results from high T4 and FT4 levels. However, this is not the case for pregnant women: T4 is more during pregnancy.
4. TSI test: This test is meant for antibody in people having the Grave’s disease. It comes with excessive thyroid secretion in the body. TSI (Thyroid Stimulating Immunoglobulin) test detects the TSI level in the blood.
Another test is the Anti-thyroid Antibody test
These are present in the blood and help in detecting the Hashimoto disease. The chief anti-thyroid antibodies are:
- Anti-TPO – attacks the enzymes of the thyroid cells.
- Anti-TG – attacks the thyroglobulin protein in the thyroid.
Thyroid tests are affected by a number of factors. The above tests are sure ways of diagnosing thyroid disorders and useful in recommending the best treatments.
