The total thyroxine test is usually seen in the five-item thyroid function test. Only elevated total thyroxine in the five-item thyroid function test is not enough to determine that it is hyperthyroidism, and it is necessary to combine with the symptoms, and it is recommended that the thyroid function be rechecked on a regular basis.
The five indicators of thyroid function are thyrotropin (TSH), free thyroxine (FT4), free triiodothyronine (FT3), total thyroxine (T4), total triiodothyronine (T3) can be used to check whether the thyroid function is normal or not, and whether there is hyperthyroidism or hypothyroidism and other conditions.
Normal human total thyroxine is T4, there are two states, one is the free state, the other is the non-free state, the role of the main free thyroid hormone, known as FT4. If the TSH significantly lower, FT4, FT3 significantly higher, while the patient has excessive sweating, irritability, emaciation, and other symptoms, it may suggest that there is the existence of hyperthyroidism.
If TSH is significantly elevated and FT4 and FT3 are significantly lowered, accompanied by symptoms such as emotional apathy, facial edema, and weight gain, this may indicate the presence of hypothyroidism.
If the total thyroxine is high and the other items are normal, we should be cautious of hyperthyroidism, but it is not enough to determine that it is hyperthyroidism. It is recommended to check the thyroid function regularly and consult the endocrinologist for further treatment.
If the total thyroxine is high and the other items are normal, it is recommended to go to the hospital for treatment under the guidance of the doctor.
