TSH Test shows TSH value 0.32 L (low). What does this mean?

I took a TSH test last week. It shows"TSH value 0.32 L (low). What does this mean? I think it's supposed to be at 3. It seems really odd because on 11/29/07 it was 2.19 and then now 6/27/08 it's 0.32 L. Could anyone tell me maybe what's going on. I'm going to make an appointment tomorrow with the doctor. Also, the T4 FREE value is 1.59 H (high). What is this? I looked in the internet and I think it also has something to do with the thyroid. My calcium is low also and the cholesterol is high. Would all this have something to do with the thyroid being off? I've had thyroid surgery about 45 years ago for overactive thyroid. I take Levothroid 125 MCG once a day religiously and also the cholesterol 20 MG once a day religiously. But, they still seem to be off. Don't understand why. Also, the calcium is always low. I take calcium every day. What doctor (specialist) should I see? Sometimes, I think, your regular doctor doesn't seem to really know about thyroid problems. They just tell you "oh, everything is ok." Any help would be appreciated. Thanks.

Re: TSH Test shows TSH value 0.32 L (low). What does this mean?

Your low TSH and high FT4 mean you are hyperthyroid once again.
It may be because your Levothroid dose is simply too high. But you could have a more complicated issue where the remnants of your thyroid tissue have regrown or formed autonomous nodules that are spewing out extra hormone and making you hyper.

Your calcium could be low because your one or more of your parathyroids might have been damaged in the thyroid surgery. I don't know much more than that about blood calcium and what causes it to be off.

Low thyroid is the second leading cause of high cholesterol following poor diet. If you've been undermedicated for a long time, that could be a contributing cause. If your TSH was over 2 for a long time previous to the 11/07 test, you might be able to blame the high cholesterol on under-replacement of your thyroid hormone. My own LDL cholesterol fell by 16 points - if I remember right - after my dose was optimized. On the other hand, your cholesterol problem may be unrelated. Any symptom that can be attributed to thyroid problems can always have unrelated causes as well.

I think you should see an endocrinologist. At the very least, you need an ultrasound of your neck to see whether the thyroid has grown back. And you need to know how your parathyroid glands are working. I'm not an expert on hyperT, but I know it's more complicated than hypoT. You need more expertise than a general practitioner.

Let us know how it turns out!
