Understanding Blood Tests for Thyroid Function in Pregnancy
As soon as you find out that you are pregnant, there is a long list of tests and checkups that you have to go through. One of the most important health factors that they check in every pregnant woman is her thyroid function. The reason behind that is because your thyroid has a direct impact on the development of your baby, especially during the first trimester. If you have an underactive or overactive thyroid during pregnancy, it can cause serious complications for both you and your baby.
That is why it is important to understand what thyroid function is, and how the blood tests work to monitor it during pregnancy.
What is Thyroid Function and Why is it Important During Pregnancy?
Thyroid function relates to the production of hormones by a gland in your neck called the thyroid gland. These hormones regulate your metabolism and energy level, among other things. Specifically during pregnancy, thyroid hormones have an essential role in the formation and growth of your baby's brain and overall development. So, it is important to keep your thyroid levels in check to ensure that it is functioning at the optimal level to maintain your own health and that of your baby.
What are the Blood Tests for Thyroid Function?
When you go for your prenatal blood tests, your doctor will request a thyroid stimulating hormone (TSH) test. This test measures the level of TSH in your bloodstream, which is a hormone that is released by your pituitary gland and that signals your thyroid to produce more or less thyroid hormones. If your TSH levels are above normal, it indicates that your thyroid is underactive (hypothyroidism). Conversely, low TSH levels indicate that your thyroid is overactive (hyperthyroidism).
Your doctor might also request another blood test called free thyroxine (FT4). This test measures the level of thyroxine, which indicates how much of the hormone is available for your body to use. If your FT4 levels are low, it indicates that your thyroid is underactive.
When Should You Get the Tests Done?
It is recommended that you get the blood tests for thyroid function done as early as possible during your pregnancy. Your thyroid function can change during pregnancy, and it's important to catch any irregularities in your thyroid function early. In some cases, your doctor may even recommend blood tests before you become pregnant if you have any prior history of thyroid disease.
Conclusion:
In conclusion, it is essential to understand thyroid function and the tests done to evaluate it during pregnancy. Maintaining proper thyroid function is essential for the optimal health and development of your baby, and the blood tests can help detect any issues early on so that they can be addressed. So, if you're pregnant or planning to be, make sure to have your thyroid levels checked regularly and work with your doctor to ensure your thyroid function is optimal. Your health and that of your baby depend on it.
