<p>In pregnancy, subclinical hypothyroidism (SCH) diagnosis relies on elevated TSH levels above trimester-specific reference ranges while T4 levels remain within the normal range. Guidelines, such as the European Thyroid Association&#39;s 2014 publication and the American Thyroid Association&#39;s 2017 recommendations, emphasize the need for locally-derived TSH reference ranges, with suggested upper limits at 2.5-3.5 mIU/L for different trimesters. In the absence of specific local ranges, the upper limit is advised to be around 4 mIU/L for the first trimester, allowing for adjustments throughout pregnancy. Factors like weight, ethnicity, and location must also be considered for accurate TSH interpretation.</p>
