Tips to Understand your Thyroid Profile Reports

Introduction

The Thyroid gland is located in the neck and produces thyroid hormones. This butterfly-shaped gland control many functions in the body like heart rate, metabolism, and other involuntary actions. Thyroid issues, in which the organ creates excessively or too little of the hormone, can impact many capacities in your body, from your heart rate to your metabolism.

If your specialist supposes you are experiencing an overactive or under-active thyroid, they may arrange thyroid profile tests.

Perusing the outcomes can appear like a mind-boggling task; but in case that you have an efficient approach and understand each test carefully, you can decide if you have a thyroid issue. Furthermore, you will be able to know more about the thyroid problem. However, you should remember that you are not a thyroid specialist at all. Even if you have read the reports efficiently, you must see a doctor and discuss it with them.

What are thyroid profile tests?

Thyroid tests or thyroid function tests are nothing but blood tests used to know the functioning of the gland. By taking a little amount of blood from the body, it is sent for the determination of hormones present in it. Generally, the amount of TSH, T3, and T4 are measured in the blood sample based on which the functioning of the thyroid gland is determined.

The thyroid gland releases to principle hormones namely T3 (triiodothyronine) and T4 (thyroxine). In case that the thyroid gland fails to produce a required amount of these hormones, you start to suffer. The symptoms include weight gain or loss, fatigue, mood swings, anxiety, etc. because of these factors; it is of prime importance that your thyroid gland works properly.

How to understand TSH results?

Verify whether your TSH perusing is in the normal range. The main thyroid test that is suggested by doctors is the TSH. TSH remains for “Thyroid Stimulating Hormone,” which is produced by the pituitary gland and animates the thyroid to make and discharge hormones T4 and T3. TSH can be thought of as the “motor” of the thyroid gland because it decides the measure of thyroid hormone that is synthesized and after that discharged from the thyroid into the body.

A typical incentive for TSH is between 0.4 – 4.0 mIU/L. If your TSH is in this range, it is a good sign; however, a typical TSH value does not totally rule out thyroid issues. Increased TSH values can indicate thyroid problems that may be growing in the gland. Most thyroid issues require at least two thyroid tests to identify and analyze. That’s why; your specialist may arrange more tests, regardless of whether your TSH is ordinary if they consider other symptoms of thyroid problems.

What does high TSH value indicate?

TSH advises the thyroid to deliver T4 and T3, which are the hormones discharged from the thyroid to act all through the body. In case that your thyroid is underactive, which means that it isn’t discharging enough amounts of T4 and T3, thus your pituitary gland will discharge more TSH to meet the T4 and T3 requirements. Therefore, a high TSH might be an indication of hypothyroidism (thyroid gland is delivering deficient measures of thyroid hormones). However, to confirm the condition of underactive thyroid, your blood sample requires further analysis.

What does low TSH value indicate?

If the thyroid test results indicate that the TSH levels are low, it may be your body controlling the pituitary gland to generate less TSH due to the presence of excess thyroid hormone (T3 and T4). And therefore, a low TSH might be an indication of hyperthyroidism or overactive thyroid (abundance generation of thyroid hormone). Again, more blood tests will be required to affirm such a conclusion. A TSH reading alone is not sufficient to completely identify the key issue. However, it can certainly guide the doctor towards right medication.

How to understand T4 and T3 results?

Check whether your T4 reading is normal. T4 is the most usually estimated hormone that is derived straight from the thyroid gland. From here it is released to circulate throughout the body. The value of free T4 ranges between 0.8 – 2.8 ng/dL in a fit person. The exact values may differ as it depends upon other factors like the lab and the particular type of test that is performed. However, most lab results will have a defined normal range which will be close to these values and hence you can clearly see if your T4 is in the normal range.

Once you have understood the T4 values, now it’s time to relate it with TSH values. If the TSH value is very high (which indicates hypothyroidism), a low T4 would bolster the determination of hypothyroidism. Also, if your TSH value is very low (which indicates hyperthyroidism), a high T4 would bolster the analysis of hyperthyroidism. But you should always remember that the outcomes are best deciphered in conjunction with the TSH values and under the direction of the thyroid specialist.

T3 values:

Survey the T3 values in instances of hyperthyroidism (overactive thyroid). T3 is another important hormone generated by the thyroid gland. But the quantities are significantly lower as compared to T4. T4 is the principle thyroid hormone utilized in the diagnosis of thyroid problems. There are some instances of hyperthyroidism when the T3 turns out to be essentially raised and the T4 stays in normal range and this is the point at which the T3 estimation turns out to be crucial.

T4 values:

In case that the T4 is in the normal range and the TSH is low, a high T3 can affirm the condition of hyperthyroidism. While the T3 can give significant data in diagnosing hyperthyroidism, it doesn’t analyze hypothyroidism. The nominal range of free T3 is between 2.3-4.2 pg/ml in adults. Just like T4 values, the exact figures may change contingent upon the lab and the particular type of test that is performed. Most lab results will have a defined normal range which will be close to these values and hence you can clearly check if your T3 is in the normal range.

Conclusion

The analysis of a person’s thyroid profile is very important as the hormone controls various body functions like heartbeat, metabolism, etc. Thyroid tests mainly include the measurement of TSH, T4, and T3 hormone levels. These are the main hormones released by the thyroid gland and pituitary gland. The results of various thyroid tests are hard to understand as no solid conclusion can be drawn by them about the condition (overactive or underactive) of the thyroid gland. However, if you follow the correct guidelines then you can probably determine the condition. But the consultation of a thyroid specialist is highly recommended.

You can combine the obtain results with the symptoms of the condition and if they match correctly then there are strong chances that you have correctly read the results. For example, if you have concluded from the thyroid test results that you have a condition of hyperthyroidism then you can check it with the symptoms of hyperthyroidism which include insomnia (difficulty sleeping), unnecessary sweating, short breathing, weight loss, etc. If you notice that you are facing above-mentioned problems then you can affirm the condition of hyperthyroidism.
