What does Cha Jia Gong mean

The thyroid gland is a very important organ. The hormones it secretes are essential substances for the body and play an extremely critical role in the normal functioning of body functions. This organ ability is also called thyroid function, or thyroid function for short. In modern life, many people suffer from hypothyroidism due to various reasons, which seriously threatens their health. Let’s take a look at what it means to check thyroid function.

As the largest endocrine organ in the human body, the thyroid gland continuously produces and secretes thyroid hormones T3 and T4 every day to maintain normal body functions. After thyroid hormone enters the blood, it is transported to various organs throughout the body.

Thyroid function tests include the following:

TSH: thyroid stimulating hormone

FT3: Free triiodothyronine

FT4: serum free thyroid hormone

TT3: serum total three-point thyroxine

TT4: serum total thyroxine

If you have abnormal thyroid function and are taking medication, it is best to check the following five items:

For some patients who have abnormal thyroid function when they first see the doctor, such as patients with Hashimoto's thyroiditis who have been diagnosed with hyperthyroidism, hypothyroidism or are in the hyperthyroidism or hypothyroidism stage, and patients who have undergone partial or complete thyroidectomy and have been taking Euthyrox to supplement thyroid hormone, doctors usually ask patients to check five thyroid function tests.

This is because TT3 is more sensitive to mild hyperthyroidism, early hyperthyroidism and recurrence of hyperthyroidism after treatment. Under the premise of normal TBG, the serum TT3 of hyperthyroidism patients can be 4 times higher than that of normal people. Through this indicator, patients with hyperthyroidism can be detected more easily.

In addition, when patients have autoimmune inflammation, such as Hashimoto's thyroiditis, T3 antibodies and T4 antibodies will appear in the serum, which will interfere with the results of FT3 and FT4. At this time, other tests, such as TRH stimulation test, are usually needed to make further auxiliary judgments.

It can be seen from this that whether it is TT3, TT4 or FT3, FT4, they will be affected by other factors in the serum. To be cautious, doctors will evaluate patients' thyroid function more comprehensively and in detail. For patients with abnormal thyroid function, they will still recommend checking five thyroid function tests.
