Thank you for your post.Can you please let me know what your question is?If the level of your FT4 is high or low it does not matter a great deal.The most important thing to look at first is the TSH.If the TSH is normal. FT4 would usually not carry much significance.Let me know if you have more questions.Rate me when you are done asking.Regards
