What is T3T4 in medicine

T3 and T4 are the main indicators for diagnosing thyroid function.

Because you are checking for heart disease, the doctor wants you to do this test in order to be more clear**, because if you have hyperthyroidism, you may have the following symptoms.

There are many types of hyperthyroidism, and the most typical clinical manifestations are hypermetabolic symptoms (mainly frequent fatigue and weakness, heat intolerance, excessive sweating, ** warm and humid, weight loss, low-grade fever [high fever only in crisis]), goiter (and tremor or vascular bruit, which is known by palpation and auscultation), ocular signs (there may be exophthalmos, or exophthalmos is not obvious, and there are manifestations such as decreased vision and blurred vision). However, the above manifestations are the most typical manifestations of hyperthyroidism, and not all symptoms must be present to be hyperthyroid. In addition, some patients with hyperthyroidism may have mental symptoms such as hyperactivity and irritability, and may also have cardiovascular symptoms such as palpitations, chest tightness, and shortness of breath, or symptoms such as hyperphagia but weight loss and increased stool frequency.

Diagnosis of hyperthyroidism is a complex process. In the actual diagnosis process, if you are a typical case, we will ask you about your medical history in detail, and the diagnosis can be made based on clinical manifestations; If your clinical manifestations are not obvious, we will diagnose your thyroid function by doing thyroid function tests and other necessary special tests (e.g. FT3, FT4, TT3, TT4, STSH).

It's also quite famous, and many people prefer it, mainly because it's more formal.

In medicine, T3T4 is the two hormones secreted by the thyroid gland. It is tetraiodothyronine (abbreviated as T4, which is commonly referred to as thyroxine) and triiodothyronine (abbreviated as T3), which are collectively called thyroid hormones.

T3 serum total triiodothyronine, which is judged by a.

A common indicator of hyperactivity or hypothyroidism.

T4 serum total thyroid volume is a common indicator for judging hyperthyroidism (commonly known as "hyperthyroidism") or hypothyroidism (commonly known as "hypothyroidism"), and it has application value for disease severity assessment and efficacy monitoring.

It is a two-name name for testing thyroid function.

T3 and T4 are thyroid tests, and the test is to check if your thyroid function is normal.

T3 and T4 represent BAI thyroid function, and T3T4 is the main indicator of DU thyroid function.

T3 is also known as the tri-DAO iothyroid version.

Orthoaminothenic acid T4 is also known as tetraiodothyronine.

They are a group of iodine-containing tyrosines, which are synthesized in thyroid gland cells using iodine and tyrosine as raw materials.

When the thyroid gland is affected by TSH and releases thyroid hormones, the glandular epithelial cells first swallow the thyroglobulin in the follicular cavity into the glandular cells through swallowing, and under the action of lysosomal proteolytic enzymes, the thyroglobulins are broken down and the T4 and T3 are released [1].Because it can resist the action of deiodinase, the molecule is small and can enter the blood circulation through the capillaries. The amount of T4 on the thyroglobulin molecule far exceeds that of T3, so the secretion of hormone T4 accounts for about 90% of the total amount, and the secretion of T3 is less, but its activity is large, 5 times that of T4.

The total daily secretion of T4 is about 96 g, and T3 is about 30 After being released into the blood, part of it binds to plasma proteins, and the other part is transported in the blood in a free state, and the two can be transformed into each other to maintain the dynamic balance of T4 and T3 in the blood, because only the free type can enter the cell to play a role. After T3 is released into the bloodstream, it mainly exists in the free form because of its small affinity with plasma proteins. About 50% of T4 deiodization is converted to T3 every day, so the role of T3 cannot be ignored.

T3 and T4 are the main indicators for diagnosing thyroid function. In order to be more clear, the doctor wants you to do this examination for thyroid disease, you must choose a regular hospital, so as not to cause unnecessary damage due to non-standard and poor service.
