In this process, your body takes free T4 and turns it into free T3. One of the most important (if not the most important) lab test to look at when it comes to your thyroid is known as free T3.ДЇree T3 is the ACTIVE thyroid hormone and it is created through a process known as thyroid conversion. While your TSH and free T4 are important measures of thyroid function they do not test every facet of thyroid function in your body. Lastly, it's possible that you may not be seeing the 'whole picture' when it comes to your thyroid. If you suspect that you may have Hashimoto's you can easily check for this condition with a blood test which checks for thyroid antibodies. When in doubt, make sure that you always look at your body and your symptoms and don't focus solely on your lab tests. In fact, many patients with Hashimoto's are not treated sufficiently because their symptoms do not always correlate with their lab results. It is well known that this thyroid condition can cause changes to thyroid lab tests which are not considered to be 'normal' (4). You may have Hashimoto's Thyroiditis.ДЄnother possibility is that you have an autoimmune disease known as Hashimoto's thyroiditis.

The chances of your lab tests being inaccurate are very low, but it's worth going through this song and dance if you don't have any symptoms and feel great. The best thing to do is to simply re-test your TSH and free T4 within 1-2 weeks. So what should you do if you feel that your results are not accurate?

If there is something wrong with the machine for one test or the calibration is not done accurately, then some of the lab tests may not be accurate. This inaccuracy stems from the fact that lab testing machines must be calibrated to normal each and every day.

This is as high as 1 in 20 lab tests and if you get a full panel of lab tests you can count that at least a few of those results are not 100% accurate. It is estimated that up to 5% of all lab tests may be inaccurate or spurious. This one is rare but it certainly does happen. This is seen as your body is attempting to compensate for the early problems described above but it does NOT mean that this is 'normal'.Д®ventually, your thyroid will be unable to meet the demand and you will experience severe symptoms (if you aren't already). So this early rise in TSH can be used as a sensitive marker for early thyroid GLAND dysfunction.Д«y the way, you may find that both your free T3 and free T4 stay 'normal' despite having a very high TSH. We also know that a high TSH is not necessary to produce adequate thyroid hormones. We know this because we know what a HEALTHY TSH level is supposed to be (3). This usually indicates an early problem with the thyroid gland itself.Д«ecause your thyroid gland is getting the stimulus from the brain to produce more thyroid hormone (hence the high TSH) but it's only capable of producing a 'normal' amount of T4. The rise in your TSH is a normal physiologic response for lower than normal free thyroid hormones and it indicates that everything is working properly.Д«ut as TSH rises it means that your thyroid gland is no longer responsive to the lower doses of TSH that it once was. Your thyroid gland is struggling but still able to keep up. Several things may account for this phenomenon.

So, while TSH tells you how responsive your thyroid gland is to thyroid hormone it doesn't give information on your free thyroid hormone levels. This rise in TSH is almost always seen as an early and sensitive marker for thyroid dysfunction! This process is how your brain and your thyroid gland regulate thyroid hormones in your blood.ДЄs thyroid hormones drop your TSH will rise to compensate to tell your gland to produce more. If your TSH is elevated this means your brain is trying to increase the 'stimulus' to your thyroid gland in an attempt to compensate for decreased thyroid hormone (1). Its job is to act on your thyroid gland (in your neck) to tell your thyroid to produce more thyroid hormone. TSH (also known as thyroid stimulating hormone) is a hormone that is produced by the pituitary gland. In order to understand this concept, you have to understand how TSH functions in your body. The first thing you should know is that having a high TSH, even if accompanied by a normal T4, is never a normal sign.ДЄ high TSH is a marker that the connection between your brain and your thyroid may not be functioning at 100%.
