Triiodothyronine (T3) is the one of the two main hormones released by the thyroid gland. It's primary role is to regulate your body's metabolism as part of your endocrine hormone system.
This test measures the biologically active unbound form in the blood - Free T3 (FT3).
Increased or decreased levels indicate an imbalance and should be interpreted alongside other thyroid markers.
By buying a laboratory test kit with professional nurse or clinic collection, you can accurately measure Triiodothyronine for total reassurance.
Professional analysis in an accredited laboratory ensures rapid result delivery.
The Vitall Thyroid Function nurse or clinic test kit includes a Triiodothyronine test and is available for just £59.00.
Tests which include a Triiodothyronine test:
High free T3 can be associated with an overactive thyroid gland (hyperthyroidism).
Many medications, including certain contraceptive birth control pills and large doses of aspirin, can interfere with total T3 test results. In general, free T3 concentrations are affected much less by these medications.
A high T3 level is often interpreted alongside other thyroid function results such as thyroid stimulating hormone (TSH) and thyroxine. Taking thyroxine (thyroid hormone replacement) can influence T3 levels.
A low free T3 result can be linked to an underactive thyroid gland (hypothyroidism).
Many medicines, including certain contraceptive birth control pills and large doses of aspirin, can interfere with total T3 test results. Free T3 concentrations are generally affected much less by these medicines.
A low T3 level is sometimes associated with hypothyroidism, but interpretation is usually made alongside other thyroid function results such as thyroid stimulating hormone (TSH) and thyroxine. Thyroxine (thyroid hormone replacement) can also influence T3 levels.
