Overview
The thyroid is a small, butterfly-shaped gland in the front of your neck that makes thyroid hormones. Thyroid hormones control nearly every organ in your body works—even the way your heart beats.Sometimes the thyroid makes too much or too little of these hormones. Too much thyroid hormone is called hyperthyroidism and can cause many of your body’s functions to speed up. “Hyper” means the thyroid is overactive. Too little thyroid hormone is called hypothyroidism and can cause many of your body’s functions to slow down. “Hypo” means the thyroid is underactive. If you have thyroid problems, you can still have a healthy pregnancy and protect your baby’s health by having regular thyroid function tests and taking any medicines that your doctor prescribes.A physical exam and a blood test will help to check for thyroid conditions. The blood test measures the levels of thyroid hormones and thyroid stimulating hormone (also called TSH) in your body. TSH is a hormone that tells your thyroid gland to make thyroid hormones.

The new recommendations for TSH levels during pregnancy are the following: First trimester: less than 2.5 with a range of 0.1-2.5. Second trimester: 0.2-3.0.Third trimester 0.3-3.0.For third trimester, the reference range for TSH, fT3, and fT4 are 0.47-5.78 (uIU/mL), 0.24-3.61 (ng/100 mL), and 0.47-5.1 (ng/100 mL), respectively.
