When you go for a thyroid diagnosis or screening, do you know what is a healthy TSH level ? Hypothyroidism may be a real problem, but are your diagnosticians fully aware of all the implications ? Read this article to find out some basic facts you will probably not find out from the medical industry.
Most Thyroid Tests Aren’t Accurate!
If you have had a family history of thyroid problems you have a good reason to be concerned about an incorrect TSH screening. It is very important to correctly interpret what is revealed in the test.
You should know that the “total T4″, “T7″, “total T3″, “T3 uptake”, “T3-by RIA” and FTI ( Free Thyroxine Index ) tests are not very reliable when it comes to determining the presence of hypothyroidism. A large majority of persons who truly have a problem with hypothyroidism are not discovered.
So…Which Tyroid Test Should I Choose?
The best test for measuring your TSH is the saliva test! Also, you can do a physical examination yourself to determine whether you have problems and is time for a test. This one is the easiest to do and you can do it yourself by just paying attention to your body. Usually, the symptoms are:
- mood changes
- eye brows are missing to the side
- very thin hair (you can literally see through it)
- very cold hands
- heavy periods
- weight gain
Most times women that do no get pregnant do not ovulate because they lack the tyroid hormone in their body.
Normal T3 and T4 Levels
If you have already taken one of the tests above that measure T3 or T4, here is an interpretation guide (as I said before, blood tests got problems and may not be relevant).
A normal T3 level is between 3-8. For T4, the range is 4-11.
If T3 and T4 levels are under 3, and 4, respectively, then your thyroid is sluggish (it’s not creating enough hormones for your body). In other words, you are dealing with hypothyroidism.
For those who have values above the normal ranges, it shows an overactive thyroid, also known as hyperthyroidism. The gland is making too much hormones.
Normal TSH Levels
The TSH levels should be at or below 2.0. If you have a level higher than 2.0 you are going to be one of those persons who have an increased risk of hypothyroidism. The tests mentioned above use levels of 4.0 together with the knowledge that the pituitary gland is hopefully already signalling the thyroid to increase its levels of hormone production. The pituitary gland is the “master” hormonal gland of the body, controlling the function of the other hormonal glands. It is apppropriately located in the middle of the brain. Hormones are important controllers of the functions of the body. If hormonal imbalances are suspected, there are many organic routes that can be taken to restore balance. Conventional drugs are usually not needed and their side effects can many times be worse on the body than the imbalance.
Many patients who have a level of 1.5 exhibit the symptoms of hypothyroidism. Clearly, new levels of reference are needed by conventional (alternative) medicine. If you are indeed getting a test, make sure to ask what are the normal values for TSH levels and if the answer is a number higher than 2.0, try to find a person with more experience.
If you do have hypothyroidism, you will need hormone replacement to get your hormone levels back to normal. Taking your replacements is a complicated process, and it is a long-term treatment (usually for the rest of your life). It will correct your problems, including the lack of energy, that results from a hormone imbalance.
How Test Results are Interpreted
Once your TSH levels are measured, the following table is used to interpret the results:
|Interpretation of Test Results|
|TSH (high), T4 (normal), T3 (normal) = Mild Hypothyroidism|
|TSH (high), T4 (low), T3 (low/normal) = Hypothyroidism|
|TSH (low), T4 (normal), T3 (Normal) = Mild Hyperthyroidism|
|TSH (low), T4 (High/Normal), T3 (High/Normal) = Hyperthyroidism|
|TSH (low), T4 (low/normal), T3 (low/normal) = Non-thyroidal illness or rare pituitary hypothyroidism|
A piece of advice…Do Not Stop Here!
Do additional tests to make sure you do not have other issues with your thyroid. Generally, if the doctors find something, they must do additional test for other hypothyroid disorders at play. If they don’t, it is your responsibility to take action. Graves disease is an auto immune disorder that has devastating effects and it goes beyond just a low T3 and T4 level. Hashimoto’s thyroiditis is another disease that consists of symptoms of both hypothyroidism and also hyperthyroidism.
