Service Providers for T3
T3 (Triiodothyronine) is a thyroid hormone that helps regulate metabolism, growth, and energy production. It is more active than T4 but is present in smaller amounts. The T3 test is used to evaluate thyroid function, particularly in cases of suspected hyperthyroidism (excessive thyroid hormone) or hypothyroidism (insufficient thyroid hormone). High T3 levels may indicate conditions like Graves' disease or thyroiditis, while low T3 levels can suggest hypothyroidism, malnutrition, or illness. T3 testing is often performed alongside T4 and TSH (Thyroid Stimulating Hormone) for a complete thyroid assessment.
