My tsh levels at 28 weeks of pregnancy is 3.4.do i need to take medications or not required?

Level is high: If a standardized laboratory test was done, then a level of 3.4 in the third trimester would be abnormally elevated. What to do next depends on why the test was done, and the results of other tests. Other thyroid testing is needed to determine if you are hyper or hypo thyroid, and a history and physical would also be prudent. Ask your physician about your result.
