Hello Steffi! Thank you for asking at

The laboratory results you mentioned are the results for examining thyroid function. The thyroid is a gland located in the neck area that functions to produce thyroid hormones. Thyroid hormone will be circulated by the blood throughout the body to regulate metabolism and keep organs in the body, such as the brain, heart and muscles, working properly. The main thyroid hormone in the human body is called thyroxine or T4. The T4 hormone can be converted to triiodothyronine or T3.

The release of the T4 hormone in the body is regulated by another hormone called TSH. In the body, T3 and T4 bind to a protein that regulates the entry of T4 to various organs of the body. The T4 that does not bind to the protein is also called free T4 or in your results it is written as T4 (B). T4 (B) acts on an organ and exerts an effect on that organ. The T4 (B) test shows how T4 works in the body. T4 (B) levels will increase in people with hyperthyroidism (excess thyroid hormone in the body) and decrease in people with hypothyroidism (lack of thyroid hormone in the body). T3 levels are also elevated in people with hyperthyroidism and are helpful in determining the severity of hyperthyroidism. TSH examination is important to determine the diagnosis and the possibility of hyperthyroidism / hypothyroidism. The normal level of the test will depend on the laboratory, but in general, the following are normal test results:

TSH: 0.5 - 6.0 µU / mL T4: 4.6-12 µg / dL T4 (B): 0.7-1.9 ng / dL T3: 80-180 ng / dL Symptoms of palpitations can indeed occurs in patients with hyperthyroidism. However, other possible causes, such as anemia, heart rhythm disorders, and the use of certain drugs, cannot be ruled out. In patients with hyperthyroidism, palpitations are usually accompanied by rapid weight loss, easy sweating, and trembling hands. Patients also sometimes experience restlessness and increased appetite.

We recommend that you bring the results of these examinations to consult with a specialist in internal medicine. You will undergo a series of examinations, from a physical exam to a heart record examination to determine what disease you have. The doctor will also provide treatment based on the diagnosis of the disease. Abnormal thyroid function tests also need to be repeated after 3-6 weeks.

That is all that I can say. May be useful.
