Why are both my TSH and T4 levels high? I understand that a high TSH usually means hypothyroidism, so why is my T4 also high? Is this a serious problem? I am really worried. Please check my report and help me understand.

TSH and T4 being high at the same time is not typical and may sometimes result from a lab variation, timing of the test, or an underlying condition like thyroid hormone resistance, which is rare. The best next step is to repeat the thyroid profile at the same lab, preferably in a fasting state in the morning. This will help confirm the result and guide further evaluation if needed.

Question

I have been taking thyroid medication since the age of 11 and have never missed a dose. I am now 23, and my menstrual cycles have always been regular. My TSH is currently below 1, and it has been maintained below 5 for several years. Will this affect my ability to get pregnant? Also, does this increase the risk of miscarriage?

Question

My wife weight is 70 kgs and height is 5 feet 1 inch. Her T3 and T4 are normal but her TSH is on the higher side. Pictures of the report are attached. Can you please let me know what needs to be done along with a description of its complications? The test report was done from Thyrocare lab. Is it okay or should I get the test done from another lab? I am awaiting an urgent response from an endocrinologist. Thanks a lot in advance.
