Re: lab results are in...
Your FT4 is too low for you to feel well. Just being within the range isn't good enough to be considered 'optimum'.
Yes, you have the right to all the tests it takes to get a diagnosis. Meep has described the method to get what you want. First, politely ask for the tests you want. If the MD tries to talk you out of them, use a little humor and say, "Please, just humor me." If he still refuses, with continued good manners, ask that he put your request and his refusal in the written record. Ask for photocopies for yourself and your insurance company. Tell him you plan to appeal his decision. Usually, by that time, he'll back down and order the tests. Of course, if he didn't see the need for them in the first place, it isn't likely he'll know how to interpret them when they do come back. You still might have to go elsewhere to find satisfaction.
