Why TSH Testing Is Unreliable in Pregnancy

I want someone's TSH closer to 1.1.3 but what happens, especially in early mid pregnancy, is your TSH is very, very influenced by your HCG hormone, so it becomes unreliable. And what's sad is OB gyns are still very much using TSH to gauge the thyroid status of their patients, which is not enough. Guys. In non pregnant patients it's not enough. But it is vastly less reliable in pregn pregnant patients. So you need a full thyroid panel. How are we going to know what someone's T4 is if we're not checking? How are we going to know what their T3 is if we're not checking in? Their TSH is so heavily influenced by HCG. Not that you can gauge someone's T4 or T3 by TSH alone outside of pregnancy either, but still very, very important. So full thyroid panels all the way is emphasis number one.
